How to reduce the fan speed on your CPU

With the exception of special fanless modifications, every computer has two or more coolers: in the power supply, on the processor, graphics card, in the case and others. And each one makes noise in its own way, and that’s bad news. Many people are just used to the noise of their system and think it should be that way. Maybe it should, but it doesn’t have to! 99% of the time computer noise can be reduced by 10%-90%, and this is good news.

As you have already understood, silence is achieved by reducing the noise from the coolers. You can do this by using coolers that are quieter by nature, or by reducing the speed of your existing coolers. Naturally, you can reduce the speed to values that do not threaten to overheat the computer! In this article we will talk about that very method. Hard disk crackle reduction programs can help reduce noise even more.

So, to reduce the speed of the cooler you can use one of the options:

  • A program to control cooler RPM
  • An “intelligent” speed control system built into the BIOS
  • Utilities from the motherboard, laptop or video card manufacturer
  • Use a special device called a reboost
  • Artificially lower the supply voltage of the fan

Those who have normal control in BIOS, don’t need to read further. But often BIOS only superficially regulates the fan speed and does not lower it to silent, and still acceptable, values. Utilities from the manufacturer are sometimes the only way to influence the fans because third-party programs often don’t work on unusual motherboards and laptops. Let’s look at the most optimal. the first method.

Change the fan speed of your video card

To change the cooler rotation speed of your graphics card it is better to use the MSI afterburner program. When you first start up, you will see the options to adjust your graphics card. Find the Fan Speed column and click on Auto in the corner to be able to make changes. Use the slider to set the fan speed percentage on the graphics card and click on the tick to check your settings.

How to adjust the computer cooler rotation speed

The temperature has a direct impact on the quality and longevity of computer components. That’s why it’s important to monitor your cooling system. It should not accumulate dust, all fans of the computer must work in normal mode, if necessary, increasing the speed during heavy loads.

Most of the users work at their computers in standard mode, without loading the components in productive games and applications. In this case the coolers on your computer can not be configured, and in this situation they will run at or near the maximum speed. To reduce the noise during operation of the computer, you need to configure the coolers, reducing the speed of their fans.

How to adjust the speed of the cooler on the CPU

There may be many reasons for the high level of noise emitted by your computer: high internal temperatures, dust contamination, a cheap and noisy cooler itself or improperly set its rotation speed. If the first three problems can only be solved by mechanical cleaning and installing a new cooling system, the last one can be solved by software, forcibly reducing the speed of the cooler.

In this article we will discuss how to adjust the CPU cooler speed in the BIOS and with the help of SpeedFan utility. By following the instructions, you can reduce the noise made by your computer or vice versa, reduce the temperature of the processor.

Getting into the ventilation system, the wind meets the air flow, turns around and creates a sound vibration. Also the reason of noise can be a human factor: a specialist who has installed the fan could not fasten or poorly fasten some parts of the device or just buy a very noisy model.

To reduce the speed, it is sufficient to lower the voltage at the armature. It changes from nominal and down. This circuit is called “motor-generator”. This way you can change the parameters on 220v motor.

Using the SpeedFan program

The program to adjust the speed of the cooler SpeedFan is the most famous utility with which users control the work of the fan. Distributed for free, it has a Russian language interface that can be enabled under “Options “.

Important! It must be connected to your motherboard via a 3-pin connector for you to control the fan. If you have several fans and they are powered directly from the power supply, then they must be switched, otherwise you will not be able to increase the speed of the cooler or decrease it.

The tool offers lots of features to manage your computer components, but we will focus on the specifics of the cooler:

  • Pay attention to “CPU 0Fan”. it shows the speed of the CPU cooler.
  • At the bottom you see several fields with percentages. You need to find the field which is responsible for the cooler. To do it this way: You change each field in turn to 50-70% and see when the “CPU 0Fan” starts to decrease the fan speed.
  • Decrease the spin speed with the selected field to make the cooler run more quietly. Don’t forget : if the fan doesn’t cool your chip sufficiently, it will overheat.

You can adjust the speed of all coolers connected to the motherboard in the same way. You can use a more flexible setting and specify not a specific value, but a range of fan speed.

The rotation speed of the blades should decrease, and the noise from the cooler should decrease. Don’t forget to monitor the CPU temperature in the “CPU” line. If it exceeds 70 degrees, run the cooler at full power.

How to reduce the CPU cooler speed

When your computer is running, all of its electronic mechanisms gradually warm up. And some components feel very warm. For example, during the game is a heavy load on the processor and graphics card. But even at normal computer idle time the temperature of some components is kept at 50-60oC above zero.

And if the system unit or laptop very rarely cleaned from dust, the heating of the main parts will occur even faster. Overheating causes the computer to constantly freeze, and the fans, trying to solve this problem, work at high revolutions. And that leads to annoying noise. Constant overheating can end in an emergency breakdown of one or more parts of the equipment.

to get rid of the constant noise, you need to reduce the cooler RPM. And there are only three causes of noise. The first is overheating of the computer components. This is especially true for laptops, especially in the summer, when the temperature in the room is often higher than normal. To reduce the number of revolutions of the cooler, you need to clean your computer or laptop or change the thermal paste on the processor.

The second reason is bad lubrication or just an old cooler. For better performance it should be cleaned and lubed.

And the third reason is that a new fan was selected with a higher rpm than needed. In this case you just need to reduce its rpm.

Argus Monitor

Argus Monitor is another monitoring program with a powerful feature to control the rotation speed of any fan. The utility has a handy and Russian-speaking interface, but it is paid (you can use it for free for 30 days).

There is a separate tab for each of the supported computer components. If you need to adjust the speed of the video card cooler, go to the tab “GPU”, on the right of the graph there is a dropdown list. select the “Manual control” (a warning window will be displayed where you should agree with the risks of further actions), set the desired speed of the cooler in percent and click “Apply”:

The fans connected to the motherboard (including the CPU cooler) are controlled in the “Motherboard” tab. Board” in the “Manage. of.”. Individual settings profiles are provided here for each cooler. For example, we need to adjust the CPU fan: in the dropdown list opposite the line “CPU Vent. 1” (in our case) also set the value of “Manual control”, set the speed with the slider and press the “Apply” button. The same can be done with any additional cooler.

The above instructions are the simplest ways to control the fan speed from the Argus Monitor. But the program is also able to take control, automatically changing the speed of a cooler, depending on the temperature of the component, which it cools. To begin with, against the name of the device (fan) it is necessary to set the value “Control” to “Manual” (in our case also set the value “Manual control”). program” and click the “Curve” button.

An additional window with a moving graph (curve) opens. By moving curve points vertically adjusts cooler rotation speed, and horizontally sets the temperature at which the program automatically sets the speed. There are 7 such points in total.

In a similar way you can automate the work of the fan of the video card or any other.

What you need to know about the speed of the cooler on your PC or laptop

If the notebook or system unit is noisy, then in most cases the fan is to blame. Its speed should be adjusted so that this unit performs quality work. In other words, it should effectively cool the chipset or graphics card. However, at the same time, it does not need to do it at maximum capacity.

The problem is that the automatic cooler speed control can not work properly all the time. Then users adjust its parameters manually. They reduce or increase the number of revolutions to make the computer run more comfortably.
