How to speed up the rotation of the cooler on the processor. How to increase the speed of the cooler on a laptop

By default, the cooler operates at approximately 70-80% of the capacity that is included in it by the manufacturer. However, if the processor is subject to frequent loads and/or has been previously overclocked, it is recommended to increase the rotation speed of the blades to 100% of the possible power.

Overclocking the cooler blades does not harm the system. The only side effects are increased power consumption of the computer/laptop and increased noise. Modern computers are able to independently regulate cooler power, depending on the current processor temperature.

There are only two ways that will allow you to increase the cooler power to 100% of the declared one:

• Perform overclocking via BIOS. Suitable only for users who have a rough idea of ​​how to work in this environment, because any error can greatly affect the further performance of the system;
• Using third party programs. In this case, you need to use only software that you trust. This method is much easier than understanding the BIOS yourself.

You can also buy a modern cooler that can independently regulate its power, depending on the temperature of the CPU. However, not all motherboards support such cooling systems.

Method 1: AMD OverDrive

This software is only suitable for coolers that work in conjunction with an AMD processor. It is distributed free of charge and is great for speeding up various AMD components.

Instructions for accelerating the blades using this solution are as follows:

Method 2: SpeedFan

Method 3: BIOS

It is advisable to increase the cooler speed only if there is a real need for it, because If this component operates at maximum power, its service life may be slightly reduced.

If you are an active user of your laptop, then sooner or later (and definitely in the hot summer) you will be faced with the problem of its overheating. It turns out that standard laptop settings initially accelerate the cooling system fans to only 30-50% of their power, saving energy for other devices. Therefore, you can make coolers work faster yourself: through the BIOS or special programs (SpeedFan, AMD OverDrive, Riva Tuner).

BIOS. If your motherboard supports the cooler adjustment function, then you will not have to install any programs, but simply change a few things in the BIOS menu settings. To do this, open it (usually the “Del” key does this immediately after turning on the laptop), go to the “POWER” section and find “HW Monitor configuration”. Here we are looking for the option responsible for the speed of the fans - we focus on the word “Fan”, since they are called differently in different laptop models. We find it, launch it with the “Enter” button, then select “Enable” and the “Profile” line. From the speed modes that appear, select “Performance” or “Turbo”, which will make the coolers work at maximum. Now save the new settings and leave the BIOS. After this, the laptop will reboot and will work with maximum cooling.

SpeedFan. Quite effective, free, simple and therefore popular program for adjusting the operation of coolers. After installing and launching the application, first of all we study the temperature indicators of our laptop devices. Where they are “off scale”, using the “up” button we adjust the rotation speed of the cooler blades, which is responsible for cooling these devices. The program allows you to manage 6 coolers, but it all depends on the laptop model - on most laptops there are only 3 of them (for the processor, video card and hard drive). When the temperature returns to normal, we simply minimize the program window without closing it.

AMD OverDrive. This utility is suitable for those who also have an AMD processor. Here, after loading the program, look for the “Fan Control” item, the “Performance Control” submenu and use the sliders to adjust the required fan power. We confirm the changes with the “Apply” button. Then we need a “Preferences” button and a “Settings” item. There, check the box to activate “Apply my last settings”, click “OK” and close the program. Now it will automatically “tune” the laptop’s coolers after each time it is turned on.

Riva Tuner. This program will work well with Intel processors. The principle of its operation is similar to the previous utility.

When adjusting the speed of coolers on a laptop towards the maximum, do not forget that in this mode they will “eat” a lot of energy.

The cooler is an important component of the cooling system of any computer. It performs the function of removing warm air. Fan speed control is performed directly from the motherboard and depends on the readings of the processor chip temperature sensor. The higher it is, the higher the fan rotation speed. Self-adjustment of the speed is most often done due to the high noise that the fan creates.

Note: when adjusting the speed yourself, you MUST monitor the processor temperature, since as the speed decreases, it increases, which can ultimately damage the chip.

How can I independently adjust the fan speed through the BIOS?

You can adjust the fan speed in the standard way - through the BIOS.

To enter the BIOS, you must press the “Delete” key at the beginning of boot (in some computers it may be “F2”, “F12”, “Esc”). Depending on the BIOS type, fan speed control is located either in the “Power” or “Hardware Monitor” tab.

In this menu you can independently adjust the fan speed.

How to adjust fan speed in Windows?

On some motherboards, changing cooler settings in the BIOS may be blocked, or the adjustment may be superficial. In this case, you can use special utilities provided by the manufacturer along with the drivers (MSI Afterburner, PCProbe). If these are not available, you can use third-party programs, for example, SpeedFan. It is very popular among users, is absolutely free and has an intuitive interface.

When you first start the program, it reads the current system parameters and fan speed.

Note: at boot time, the computer fan should be running at maximum speed, since the utility reads the current fan speed and takes it as 100%.

The first block displays information from detected cooler sensors. The second contains information from device temperature sensors. The third is for adjusting the fan speed. In the “Speed01” item you can set the desired speed level (in percentage).

When is it impossible to independently adjust the fan speed on a computer?

It is impossible to adjust the cooler rotation speed if the motherboard does not have such support. Usually these are coolers with a 3-pin connector. To make it possible to control the fan speed on your computer, you need to purchase a cooler with only a 4-pin power connector or buy a speed controller to which the fan is connected directly. In this case, the adjustment is performed directly on the removable block, which is called a reobass.

Also, in most laptops, the speed control function is also not available (again due to the 3-pin connector). Only a few models that require the use of manufacturer’s programs have such support. This was done to avoid overheating, since the compactness of the components limits heat transfer. Therefore, it is not recommended to change the fan speed manually.

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 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 this way 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.

Question from a user

Good afternoon.

After playing one computer game for 40-50 minutes (note: the name has been cut out), the processor temperature rises to 70-80 degrees (Celsius). I changed the thermal paste, cleaned it from dust - the result was the same.

So I’m thinking, is it possible to increase the rotation speed of the cooler on the processor to the maximum (otherwise, in my opinion, it rotates poorly)? Temperature without processor load - 40°C. By the way, is this possible due to the heat? Otherwise, it’s about 33-36°C outside our window...

Arthur, Saransk

Good day!

Of course, the temperature of the components and the load on the cooling system greatly depend on the temperature of the room in which the computer is located (therefore, overheating is most often encountered in the hot summer months). The fact that your temperature reaches 80 degrees is not normal (although some laptop manufacturers allow such heating).

Of course, you can try setting the cooler rotation settings to maximum (if this is not already the case), but I would still recommend taking a set of measures (you can learn about them from the article on measuring and monitoring the temperature of the processor, video card, HDD -).

By the way, the other side of the coin also often arises: coolers spin at maximum and create a lot of noise (while the user does not load the computer with anything at all, and they could spin much slower and quieter).

Below I will look at how you can adjust their rotation speed and what to pay attention to. So...

Increasing/decreasing the rotation speed of coolers

In general, on a modern computer (laptop), the rotation speed of the coolers is set by the motherboard, based on data from temperature sensors (i.e., the higher it is, the faster the coolers begin to rotate) and loading data. Parameters from which the mat is based. The board can usually be set in the BIOS.

How is the rotation speed of a cooler measured?

It is measured in revolutions per minute. This indicator is designated as rpm(by the way, it measures all mechanical devices, for example, hard drives).

As for the cooler, the optimal rotation speed is usually about 1000-3000 rpm. But this is a very average value, and it is impossible to say exactly which one should be set. This parameter greatly depends on the type of cooler you have, what it is used for, the room temperature, the type of radiator, etc.

Ways to regulate the rotation speed:

SpeedFan

A free multifunctional utility that allows you to control the temperature of computer components, as well as monitor the operation of coolers. By the way, this program “sees” almost all coolers installed in the system (in most cases).

In addition, you can dynamically change the rotation speed of PC fans, depending on the temperature of the components. The program saves all changed values, operation statistics, etc., into a separate log file. Based on them, you can see graphs of temperature changes and fan speeds.

SpeedFan works in all popular Windows 7, 8, 10 (32|64 bits), supports Russian language (to select it, click the "Configure" button, then the "Options" tab, see the screenshot below).

Main window and appearance of the SpeedFan program

After installing and launching the SpeedFan utility, the Readings tab should appear in front of you (this is the main window of the program - see the screenshot below). In my screenshot, I conditionally divided the window into several areas to comment and show what is responsible for what.

1. Block 1 - the "CPU Usage" field indicates the load on the processor and its cores. Nearby are also the “Minimize” and “Configure” buttons, designed to minimize the program and configure it (respectively). There is also a checkbox in this field “Automatic fan speed” - its purpose is to automatically regulate the temperature (I’ll talk about this below);
2. Block 2 - here is a list of detected cooler rotation speed sensors. Please note that they all have different names (SysFan, CPU Fan, etc.) and opposite each has its own meaning rpm (i.e. rotation speed per minute). Some sensors show rpm at zeros - these are “junk” values ​​(you can ignore them *). By the way, the names contain abbreviations that some may not understand (I’ll decipher them just in case): CPU0 Fan - fan on the processor (i.e. a sensor from a cooler plugged into the CPU_Fan connector on the motherboard); Aux Fun, PWR Fun, etc. - the rpm of the fans connected to these connectors on the motherboard is similarly shown. board;
3. Block 3 - the temperature of the components is shown here: GPU - video card, CPU - processor, HDD - hard drive. By the way, there are also “garbage” values ​​here that you shouldn’t pay attention to (Temp 1, 2, etc.). By the way, it’s convenient to take the temperature using AIDA64 (and other special utilities), about them here:
4. Block 4 - but this block allows you to reduce/increase the rotation speed of coolers (set as a percentage. By changing the percentages in the columns Speed01, Speed02- you need to look at which cooler has changed speed (i.e. what is responsible for what).

Important! The list of some indicators in SpeedFan will not always coincide with the cooler it is signed with. The thing is that some computer assemblers connect (for one reason or another), for example, a processor cooler not into the CPU Fan socket. Therefore, I recommend gradually changing the values ​​in the program and looking at changes in the rotation speed and temperature of the components (even better, open the roof of the system side and visually watch how the fan rotation speed changes).

Setting the fan speed in SpeedFan

Option 1

1. As an example, it will try to adjust the rotation speed of the processor fan. To do this, you need to pay attention to the column "CPU 0 Fan" - this is where the rpm indicator should be displayed;
2. Next, change the values ​​in the columns “Pwm1”, “Pwm2”, etc., one by one. When the value has been changed, wait a while and see if show has changed rpm, And temperature (see screenshot below);
3. When you find the right one Pwm- adjust the cooler rotation speed to the optimal number of revolutions (about the processor temperature I , I also recommend for review) .

Option 2

If you want the smart operating mode to be enabled (i.e. so that the program dynamically changes the rotation speed, depending on the processor temperature ), then you need to do the following (see screenshot below):

1. open program configuration (note: "Configure" button) , then open the "Speeds" tab;
2. then select the line that is responsible for the cooler you need (you must first find it experimentally, as recommended in option 1, see just above in the article) ;
3. now in the “Minimum” and “Maximum” columns, set the desired percentage values ​​and check the “Auto-change” box;
4. In the main program window, check the box next to "Auto fan speed". Actually, this is how the rotation speed of coolers is regulated.

Addition! It is also advisable to go to the “Temperatures” tab and find the processor temperature sensor. In its settings, set the desired temperature that the program will maintain and the alarm temperature. If the processor heats up to this alarming temperature, then SpeedFan will start spinning up the cooler at full power (up to 100%)!

For those who do not have SpeedFan

Setting up automatic adjustment of cooler rotation in the BIOS

The SpeedFan utility does not always work correctly. The fact is that the BIOS has special functions responsible for automatically adjusting the rotation speed of coolers. They can be called differently in each BIOS version, for example, Q-Fan, Fan Monitor, Fan Optomize, CPU Fan Control etc. And I’ll immediately note that they do not always work correctly, at least SpeedFan allows you to very accurately and subtly adjust the operation of the coolers, so that they perform the task and do not interfere with the user ☺.

To disable these modes (the photo below shows Q-Fan and CPU Smart Fan Control), you need to enter the BIOS and set these functions to Disable. By the way, after this the coolers will operate at maximum power and may become very noisy (this will happen until you adjust their operation in SpeedFan).

Hotkeys to enter the BIOS menu, Boot Menu, restore from a hidden partition -

That's all for today, good luck to everyone and optimal fan operation...
