Cooler acceleration program. What programs are suitable for cooling a laptop?

A fan or cooler (as it is also called) is designed to cool computer parts that heat up during operation. However, it happens that overheating of parts is not observed, but the cooler works too actively, causing too much noise. The opposite situation also happens: when the PC is heating up, but the fan does not want to work at all. In this article we will figure out how to increase or, conversely, decrease the rotation speed of the cooler on a laptop.

You can increase or decrease the fan speed programmatically

The fan rotation speed itself is determined by the motherboard based on the settings in the BIOS. It just so happens that these settings are not always optimal, and this, in turn, leads to the fact that the laptop either makes noise as if it is trying to take off, or gets so hot that you can get burned. You can solve this problem directly in the BIOS or using third-party programs. Let's consider all the methods.

Setting up through the BIOS may not seem very convenient, since this method does not always work as well as we would like. And if you need to configure everything manually, on the fly and quickly, then the BIOS is not a help at all. If you do not have a laptop, but a desktop computer, then the cooler may not be connected to the motherboard, which makes configuration via the BIOS completely impossible.

The most convenient option is to use special software to adjust the fan speed. There are plenty of similar software products, there are even plenty to choose from.

A simple, good, and most importantly, free program, Speedfan, perfectly solves the problem; in this article we will analyze this utility in more detail because of its convenience and popularity. Its interface is quite simple to understand, and therefore even the absence of Russification is unlikely to create any difficulties when working with it.

The Speedfan installation is standard, we won’t dwell on it. Immediately after installation, the utility will collect all the necessary information about the fans installed on the computer and show it to you in the form of a list.

Areas that you should pay attention to are highlighted in red. The top block indicates the rotation speed of each cooler in RPM (revolutions per minute), and the bottom block shows their parameters, which can be adjusted. As for the top block, CPU Usage shows the processor load level (a separate scale for each core). If you check the Automatic fan speed checkbox, the rotation speed will be set automatically. It is not recommended to use this function due to its ineffectiveness. In the end, the program was installed not for automatic, but for manual configuration. The window may also look like:

If the fan is connected not to the motherboard, but to the power supply, then the values ​​will not be displayed. This is not your fault, it was done by default. If you want the parameters to be displayed and all coolers to be detected, you will have to reconnect them to the motherboard.

You can adjust the rotation speed of each fan in the Speed ​​parameters block. Just use the arrows to set the percentage values. It is highly not recommended to turn off any coolers, as this can lead to overheating and damage to the laptop.

In the event that you do not know which cooler is working incorrectly, you need to change the Speed ​​value for each until you notice the difference by ear. Please note that the percentage value you set will be constant, that is, it will not change depending on the load level.

A separate story is the video card fan. It is this part of the laptop that often heats up the most, which means that the correct operation of the cooler is especially important here. The MSI Afterburner program is well suited for setting up the fan on a video card. It works with all video cards, which makes it very convenient. This utility has automatic speed adjustment enabled by default. This feature should be disabled.

Use the slider to set the required speed value. The graph next to it will display all changes in work. Thanks to this, it will be convenient for you to choose the optimal settings.

How to increase the speed of the cooler on a laptop if over time it starts to work a little slower, more noisy and sometimes even overheats. Overheating is one of the most inconvenient and harmful incidents for a computer because it causes additional wear and tear on the hardware and increases the chances of failure.

To eliminate this situation, you can replace the thermal paste and increase the cooling. If replacing thermal paste is not a very difficult matter, then in order to strengthen the cooling system (CO), you need to either buy a cooling pad or increase the speed of the cooler. The cooling pad is quite noisy, costs extra money, and takes up space, but you can speed up the standard cooling system absolutely free.

There are two options for how to speed up the cooler speed on a laptop:

1. Using the software
2. Using BIOS\UEFI

Before overclocking

First, let's determine what the speed of the cooler will affect:

• The higher it is, the more noise the laptop makes when operating, the faster it discharges (slightly), but at the same time the temperature of the CPU and the system as a whole is lower, which means there are fewer freezes and slowdowns due to throttling (lowering the processor frequency to reduce the thermal load). The power supply design is High Performance.
• The lower, the quieter the laptop runs, the slower the battery discharges, but under high loads there is a possibility of the device overheating. The power supply scheme is Energy Saving.

In most cases, cleaning the cooling system and replacing the thermal interface solves the problems of overheating and throttling. But if these manipulations are difficult to perform due to the complexity of disassembling or the warranty of the laptop (which prohibits disassembling the device), then to obtain the desired cooling it is better to speed up the cooler.

Overclocking a cooler via software

One of the most popular programs for monitoring and tracking system temperature - Speedfan - will answer the question of how to increase the speed of the cooler on a laptop. You can download the program on the website or via a direct download link.

Please note that not all laptops are supported by this program. It is likely that very old devices, or, conversely, new generation devices, may not display information on temperature and cooler speed. You can view the list of supported buses or axles (BUS) on the utility website.

Install and open the SpeedFan application. The main window will display main information on the temperature and rotation speed of the coolers. Click on Configure, which will open the configuration window. Select the required tracking component - for example, this is the CPU (CPU) and set the desired temperature, the cooling system will work with priority at this parameter.

The next parameter in the Speeds tab determines the speed of the coolers.

1. Minimum value – minimum value (%)
2. Maximum value – maximum value (%)
3. Automatically varied – automatic selection based on temperature

After using the utility, check the temperature readings; if they have not changed within a few minutes\hours, try changing them through the BIOS.

How to increase the fan speed on a laptop via BIOS

BIOS allows you to configure various device parameters - from boot parameters to login password and regulation of processor or memory frequency. Not all laptops have the ability to overclock CO, so you need to check this option on your laptop.

To enter the BIOS\UEFI of your computer when rebooting, press the corresponding key:

If you have a classic BIOS, open the Power tab and select Hardware Monitor

Then, if you have the ability to control the minimum cooler speed or set a target temperature value, set the necessary settings.

• For temperature - the lower the better – 40-55 C°
• For speed - it is better to test on your device - select from 100% to 35% in steps of 5-10% to determine the acceptable noise level and temperature.

For owners of laptops with UEFI, the interface is slightly different, but the functionality is much richer.

The desired settings will be in the Monitor, Hardware or Advanced tabs. Settings may vary depending on manufacturer and UEFI version.

Additionally

How else can you increase the speed of the cooler on a laptop:

• For older devices, special utilities AMD OverDrive or Riva Tuner may be suitable. The list of supported devices is extremely small and mostly consists of outdated laptops based on Windows XP, Vista or sometimes version 7.
• There have been cases where dust interfered with the cooling system so much that the bearings needed to be lubricated
• Don't rule out the possibility of replacing the cooler if the speed is very different from the advertised speed.

Have a great day!

Good day, computer users. The topic of our conversation today worries many: how to make the cooler much quieter.

Often the main reason for the loud operation of the cooler is the presence of a layer of dust on it. This is easy to check without even removing the cover from the system unit. It is enough to give the PC a small load, and the cooler starts spinning at maximum speed (and no drop in temperature is observed).

You should clean the dust in the entire system yourself or order subscription service for your computers. If cleaning does not help, you should find out if the cooler has any mechanical damage.

These simple steps can often help reduce noise, but in some situations they are not enough. If you are completely sure that the noise is not due to dust, then you are faced with a problem that needs to be solved by other methods. Most likely, the matter is in the rotation parameters, namely, in the given torque. It turns out that even during normal loading of the PC, a lot of noise appears, which means that the speed is high. In this article you will learn how to correctly set the optimal fan speed.

So, let's begin.

Correct cooler speed: how to achieve it? Speed ​​fan

Fan adjustment is done using the motherboard. The required speed is calculated based on the temperature data and the settings specified in the Bios. The motherboard independently regulates the rotation speed by changing the voltage/resistance, which allows it to control the speed based on user-specified settings. In addition, the temperature of the PC inside the case is taken into account.

But these actions do not always lead to setting the correct cooler rotation speed, despite “smart” technologies. In most cases, there is a choice of either the maximum rotation speed or the minimum. The first option causes excessive noise, the second ─ the cooler is much quieter, but the speed is not enough for normal cooling. There are at least 3 options to solve the problem:

• attempt to enter the required values ​​using Bios;
• physical impact on the operation of the cooler with the subsequent connection of various physical. devices capable of changing the rotation speed;
• installation of specialized software for speed control.

The first option may seem the simplest, but it is not suitable in all cases. No one can guarantee that all coolers are powered by motherboards. boards , which means Bios may not even be aware of their presence. This often applies to case fans. In reality, everything looks like this: they work at full capacity, which is unnecessary, and produce unnecessary noise.

Physical intervention can help, but for this the owner must have the necessary knowledge of physics and electronics, and understand how the rotation speed can be changed. And besides, there is no guarantee that your intervention will not lead to damage to the fan, and cutting the wires itself is not an easy task. Ultimately, you can end up with a cooler whose rotation speed is forced to change, and it will not be possible to increase it if necessary.

The solution may be to buy a reobass. You need to connect everything through it and easily change the rotation speed. However, this is quite expensive, and many people do not like this method because they have to change the set speed each time, which can only be done manually.

Having analyzed the two methods, we smoothly moved on to the most important thing - installing special programs for adjusting the speed. If you try, you can even find free programs, among which the highest quality is Speed ​​fan. This utility completely copes with the adjustments and will be your salvation. The only problem is that this program is in English, but the interface is quite simple and you will quickly figure it out. Installing a program is several times easier than installing a game.

When you launch the utility for the first time, the following window may appear:

Click on the “Do not show again” checkbox, then “Close”:

So, let's figure it out. Regardless of whether it is a new version of the program (picture above) or an old one (picture below), the principle of operation is the same. The only difference is the different value signatures.

“Cpu Usage” ─ this field with indicators shows how much the processor and its cores are currently loaded. “Configure” opens the program settings, “Minimize” minimizes it.

“Automatic fan speed” ─ it makes no sense to enable this checkbox, because then the cooler will rotate at the original speed, which will reduce the benefit of the utility to zero. It makes no sense to install a program and not change the speed. If you don’t want to waste your own time, order computer repairs in Butovo at a time convenient for you.

IMPORTANT! There is a 100% guarantee that the coolers in your PC are installed in the right places, so when choosing CPU or Fan1 for the first time, you need to remove the cover of the system unit and observe which cooler will work slower (faster) when changing parameters in the program. This is worth dealing with from the very beginning, since the program may incorrectly read information about coolers, and they may be connected to the motherboard sockets incorrectly.

Next is a set of indicators of the rotation speeds of certain fans (on the left) and the temperatures of components (on the right) at the current moment. So which is which? Let's look at the example of rotation speed, which is measured in RPM (rpm):

• SysFan (Fan1) ─ shows the rotation speed of the fan plugged into the SysFan socket on the motherboard. A chipset cooler or any other cooler connected here by mistake can be connected here (each motherboard connector has a specific signature);
• CPU0 Fan (Fan2) ─ parameter showing the speed of the fan on the processor, provided that it is plugged into the CPU_Fan slot;
• Aux0 Fan (Fan3) ─ provides information about the current rotation speed of the cooler plugged into the AUX0 connector;
• CPU1 Fan (Fan4) ─ similar to CPU0, works if there is a second processor or a connector for a cooler labeled CPU1_Fan;
• Aux1 Fan (Fan5) ─ similar to Aux0, shows the rotation speed of the knob connected to the AUX1_Fan connector;
• PWR Fan (Fan6) ─ indicates the speed of the cooler located in the power supply? or the speed of any fan connected to the PWR_Fan connector on the motherboard.

Particular attention should be paid to the fact that these parameters completely coincide with the motherboard connectors, into which you can connect absolutely any cooler from the listed ones, and the indicator will be in the corresponding column of the utility. This is only possible if the cooler is connected via a small 3-pin connector on the motherboard. For clarity, take a look at the photo. The first photo is with the correct connector (4-pin) and socket (3-pin). Speed ​​adjustment is allowed:

The wrong connector (power supply to the power supply) does not allow monitoring and changing the speed even using the program:

If you find this method of powering coolers from the power supply in your computer, it is better to re-plug the plugs into the connectors on the motherboard. This will allow you to change operating parameters using the utility.

As mentioned above, the temperature of the components is indicated on the right, but the indicators of this program are not always adequate and accurate, and this parameter is better controlled using analogues HWMonitor or AIDA64, which give the most accurate values. Taking into account their readings, set the settings:

Now we have reached the most important thing - speed adjustment. This can be done in one way: opposite the inscriptions Speed ​​(01-06) or Pwm1-3 Pwm1-3 (for newer versions) there are arrows that set the fan rotation speed. They are exactly what we need. If you press them, you can hear how the rotation speed of the coolers changes. Here you can understand what the minimum volume of your PC is.

To understand in which column the speed of each cooler is located, click on the arrows and see where the RPM will change. You cannot turn off the fans completely, as there is a risk of burning something. When adjusting, you should also monitor the temperature.

Disable/enable fan speed control in BIOS

Some motherboards and their BIOS types may block the program. This occurs because automatic or pattern-based throttling is enabled or disabled in the BIOS.

You may encounter incorrect operation of the program and problems that arise, or you decide to connect speed control using the motherboard. Then you will need to go into the BIOS and activate or disable the adjustment system. You can do it like this:

If Q-Fan is in the Enable position, then automatic control is enabled, if Disable control is performed manually using the utility. Depending on what type of BIOS is in your PC, this parameter is located. It may be in other tabs and have a different appearance. Sometimes it is necessary to switch the CPU Fan Profile from Auto to Manual (or vice versa).

There may be many options for the location of this tab, but it is required on every computer, and you can find it. Perhaps it will be called CPU Fan Contol, Fan Monitor, etc.

Afterword

The program has other tabs that are responsible for completely different components. This program may be exactly the utility you have been looking for for a very long time. Keep your PC productive and quiet.

Today we will talk about coolers. The term “cooler” was formed by transcribing the English word “cooler”, which translated means “cooler”. To put it simply, a cooler is a regular fan used to cool the central processor, video card, power supply and other heating elements of the computer.

The cooler has one unpleasant side - they make noise during operation. And the more coolers your PC uses, the more noise they make. In this article, we will look at how to simply and effectively reduce the noise produced by a fan.

Why are coolers noisy?

If you do not take into account special fanless modifications, then each computer has two or more coolers. As mentioned earlier, this can be a cooler on the processor, on the graphics accelerator, in the power supply, as well as fans installed on the side and rear walls of the system unit case. And each of the listed fans creates a separate noise, and together it sometimes turns into a rather unpleasant hum. Some PC users have simply gotten used to this noise in their system unit and do not pay attention to it, believing that such a hum is in the order of things and nothing can be fixed. But there is good news! In 98% of cases, the noise from computer fans can be reduced by at least 10%, and at most by 90%.

As you may have guessed, the noise level in a working fan depends mainly on its rotation speed. As the rotation speed decreases, the cooler noise also decreases. Fortunately for us, there are wonderful programs with which you can easily control coolers by changing their rotation speed. Of course, you can reduce the fan noise by replacing it with a more expensive and low-noise analogue. However, such a replacement will not always give the expected effect, proportional to the money spent. Therefore, we will consider a less radical way to reduce noise, which is a program for adjusting the speed of the cooler. Naturally, reducing the number of fan revolutions has its limit, which does not threaten overheating of the computer. And if the adjustment is made incorrectly, problems may arise. We will try to explain everything in as much detail as possible so that you have absolutely no problems when changing your settings.

To complete the picture, it is worth mentioning that in addition to programmatically changing the cooler rotation speed, there are several other ways in which you can reduce the fan speed: the cooler speed control system, which is hardwired into the BIOS; use of a special device - reobass; artificially lowering the cooler supply voltage.

If control works well from the BIOS on your computer, then you don’t need to read this article further. But, as practice shows, very often the BIOS regulates the cooler speed only superficially. The underestimation occurs with a large margin of safety, which, unfortunately, is not always justified and does not lead to a reduction in noise from the fan.

Now let's try to define rheobass. What is it and what does it serve? Most often, the rheobass is a device that is mounted in a computer bay measuring 5.25" or 3.5". It serves for manual adjustment of the rotation speed of coolers in the system unit.

Sometimes there are reobass models made for a PCI slot or even made in the form of a regular adapter for a cooler power cable. A similar device has one or several regulators on the front panel, with the help of which the fan speed is adjusted. When choosing a reobass, first of all you need to pay attention to the presence of a sufficient number of adjustment channels. In simple words, you need to buy a rheobass that can adjust the speed of all fans in the system. Also, when choosing a reobass, it makes sense to pay attention to the length of the wires, so that it is sufficient to connect all coolers. Additionally, you need to clarify the possibility of connecting the rheobass to the FAN connector on the motherboard, which is necessary to display changes in fan speed in the operating system. This option may, of course, not be needed if the selected rheobass has an LCD display, on which the temperature from the sensors and the rotation speed of the coolers will be displayed. But any reobas costs money, and not everyone has a free amount of money that can be spent on such a thing, which is far from essential. Therefore, to save your money, let's consider a program that serves to reduce the number of revolutions of coolers - SpeedFan.

SpeedFan cooler management software

SpeedFan is a multifunctional and completely free program. SpeedFan is capable of controlling the cooler speed automatically. You will immediately have to be a little disappointed that this program is not able to work on all modern laptops, but this fact can only be verified by running these utilities. In addition, the SpeedFan program is capable of adjusting the rotation speed of only those fans that can be controlled by the motherboard from under the BIOS. For example, in the case we are considering, from the BIOS you can enable cooler control exclusively for the central processor. But at the same time, you can view the current rotation speed of two more fans. Now the most important thing, before you start using the SpeedFan program, you must disable cooler management in your computer’s BIOS! If this is not done, then the operation of the coolers may proceed according to the following scheme. When the SpeedFan program is loaded, it reads the current speed of the coolers, which it takes as the maximum values. Therefore, if by the time the program starts the BIOS cannot spin up the fans to maximum speed, then the program will not do this either. Let’s assume the following situation: at the time the program was launched, the fan on the central processor was rotating at a speed of 1100 rpm; SpeedFan, taking this rotation speed as the maximum, was unable to increase it when the processor further warmed up. As a result, the processor will continue to heat up to a critical temperature and if its automatic overheating protection does not work, it may fail before it has time to shut down. An experienced user, of course, will be able to grasp this point, noticing that when the load on the processor increases (let’s say running a game), the fan does not increase its speed (read, the noise it produces increases), but such a risk is not justified. Therefore, we remind you once again that before launching the SpeedFan program, be sure to disable fan speed control in the BIOS.

When you first launch the SpeedFan program, a window will appear on the monitor screen offering a description of the program’s functionality. Here you can check the box and close it so that the next time you start this message, this message will not be displayed on the screen. After this, the program will read the parameters of the motherboard microcircuits and the values ​​of the temperature sensors. As a result of successfully completing this task, a window should appear in front of you with a list of the current fan speed values, as well as the temperature of the sensors on the monitored PC components. After this, you need to go to the “Configure -> Options” menu and change the language to “Russian”.

As you can see in the screenshot, the window also displays the processor load level and voltage information.

Block “1” lists the detected fan speed sensors under the names Fan1, Fan2, etc. In this case, the number of sensors in the list may exceed what actually exists. Pay your attention to the values, for example, line 2 - Fan2 and line 4 - Fan1, they have real numbers of 2837 and 3358 revolutions per minute (RPM). But the rest of the indicators are either equal to zero, like the value of Fan3, or a value called “garbage” is indicated (in the picture this is the value indicated in the first line). We will delete the extra lines later.

Block “2” indicates the temperature sensors that are detected in the system. GPU is the video card chipset, HD0 is the hard drive temperature sensor, CPU is the sensor on the central processor (instead of the CPU in the Temp3 picture). The rest of the readings are garbage (the temperature of the sensors in the working system cannot be 17 or 127 degrees). This is the main drawback of the program, that it is necessary to guess which value corresponds to which component of the system unit. For the sake of truth, it is worth mentioning that on the official website you can select the necessary configuration from the known ones, but this procedure is not easy, and besides, all descriptions are available only in English.

If you have difficulty identifying sensors, you can use another utility that is used to obtain parameters of the system as a whole, for example AIDA64. And after launching this utility, you can easily compare its indicators with the SpeedFan parameters, thereby determining which temperature and speed indicators relate to which component of the system unit.

Block “3” contains speed adjustments Speed01, Speed02, etc. With these adjustments you can set the rotation speeds as a percentage (sometimes these can be designated as Pwm1, Pwm2, etc.). At this stage, we are interested in one question: which indicator out of the six Speed01..06 is responsible for which Fan1..6. To determine this, you need to change the value of each Speed ​​one by one from 100% to 85-50% and observe how much the speed of a particular Fan has changed. Thus, after running through all the Speed ​​lines, you remember which of them corresponds to which Fan line. We repeat once again that only those fans that the motherboard is capable of controlling from the BIOS will be regulated.

Fan assembly

SpeedFan Settings

Now let's move on to the program settings. To do this, go to the “Configuration” menu and rename all sensors with names that you understand, so that in the future you will no longer be confused about which value refers to which component. In our example, we will programmatically regulate the rotation speed of the cooler on the central processor.

Go to the “Temperatures” tab and find the temperature sensor you defined a little earlier on the processor (in our example it’s Temp3) and click on it first once, and then a second later again, after which you can enter absolutely anything you like in the name field name, for example "CPU Temp". Then, in the settings field below, enter the value of the desired temperature, which will be maintained by the program at the minimum possible rotation speed of the selected cooler, and also indicate the “alarm” temperature at which the maximum fan speed will turn on on the selected device.

In our case, the desired temperature is 40 degrees, and the alarm temperature is set to 50 degrees Celsius. Naturally, for each case this temperature will be different, so the optimal ratio can only be selected by experimentation.

After this, you need to expand the branch and uncheck all the boxes, except for the Speed ​​one, which adjusts the Fan speed corresponding to your cooler. In our example this is Speed04. Next, uncheck the remaining temperatures that you do not want to be displayed in the main SpeedFan window.

On the “Fans” tab, find the necessary coolers, rename them in accordance with their purpose, and disable the rest.

Fans

After that, go to the “Speeds” tab. Go to the Speed ​​line that is responsible for the desired fan, rename it (in our example it’s CPU Speed) and set the necessary parameters: minimum – the minimum percentage of the maximum cooler speed that can be set by the program; maximum – percentage of the maximum cooler speed. In our case, the minimum is set at 55%, and the maximum at 80%. It is not surprising that the program for controlling coolers cannot set a value equal to 100%, because in the “Temperature” tab we have already set the “alarm” value, upon reaching which the cooler speed will be forced to be set to 100%. Also, in order for the regulation to occur automatically, do not forget to check the “Auto change” checkbox.

Auto change

This completes the settings, you can go to the main program window and check the “Auto fan speed” checkbox. After this, the cooler speed will be adjusted automatically. Of course, you won’t be able to set the optimal fan speed settings the first time, so you’ll have to experiment a little.

Additional SpeedFan options

The SpeedFan program has a whole bunch of additional functions and parameters with which it can control the speed of each cooler individually. There is no point in considering all of them, since it may take another page; we will describe only a few that are the most useful from our point of view.

Go again to the “Configuration -> Options” tab. After that, check the “Launch minimized” checkbox. It is necessary, as the name suggests, so that SpeedFan starts when Windows boots in minimized mode. If this checkbox is not checked, then after loading the operating system the main window will be displayed on the desktop. It should be noted that if the program does not start automatically, then its shortcut should be added to the startup folder.

The next checkbox that needs to be checked is called “Static icon”. You need to activate this option so that the program is displayed in the system tray as a simple icon, and not as numbers. But this, as they say, is a matter of taste.

The “Minimize when closing” checkbox should be checked so that after clicking on the “red cross” the program does not close, but simply minimizes it to the system tray.

The “Full fan speed on exit” checkbox is checked so that after closing the program (exiting it), the fan speed is set to the maximum. If this item is not activated, then after closing the program, the speed will remain at the level corresponding to the moment of closing. And this, when the load on the processor increases, is fraught with its overheating, since nothing controls the processor cooler.

Summing up the article, we can safely say that now, using the SpeedFan program, you can independently adjust the speed of the coolers in the system unit, and also reduce the noise in your apartment.
