Your computer is usually equipped with several fans. There are typically one or more to cool the CPU, one or more to cool the graphics card depending on the model.

Even though they are needed to keep the electronics cool, they should not be too loud. These fans should be practically unnoticeable if you’re not running any resource-intensive applications like gaming or video editing. Today, we’ll take a look at several methods for slowing down the CPU fan speed.

The way you manage your fans is very dependent on your computer, your fans, and the way everything is connected, so let’s start with the fundamentals of fan control.

What Fans Do To Keep A Computer Cool?

The computer fans know when it is appropriate to accelerate and when it is necessary to slow down. They contain built-in sensors that check the temperature of your system regularly. When it exceeds a specific level, they begin spinning to cool it down.

Factors Contribute To Fans Becoming Too Loud

Firstly you should know about the reasons why your CPU fan is becoming too noisy. The following are the most often cited reasons.

  • If you play plenty of video games or use video editing software, there is a chance that your computer fans will become too noisy.
  • Your Computer CPU and GPU are sometimes overworked and overheated. Remember to give it rest regularly.
  • Sometimes the issue is as simple as dust buildup, in which case all that is required is to open up the hardware and give it a thorough cleaning.

How To Slow Down CPU Fan Speed?

1. BIOS Configuration

Before you install any fan speed control software, you should go into the BIOS of your computer system. Most modern computers already have controls built-in, which is a great convenience. 

To access the BIOS, you must first reboot your computer and then hit the f12 key on your keyboard. You will now have to search for the fan settings in the BIOS since the position and title of the settings change from system to system.

Finally, you can adjust the speed of the CPU and system fans using this technique. Additionally, if you are unable to find any fan settings in your BIOS, to begin with, this indicates that your motherboard most likely does not support this feature at all. If this is the case, you should proceed to the following procedure.

2. Keep an Eye on Dust

Sometimes a little housekeeping is all that’s needed to fix your issues instead. When it comes to PCs, dust is a big issue since they attract it like no one’s business. A buildup of material in or around the fan ports may make it more difficult for hot air to leave. Thus dust causes the fans to work even harder than they already are.

Dust can easily remove with the use of a vacuum cleaner. Another alternative is to use a can of compressed air in this situation.

3. Use Software

Even though we’re mostly talking about PCs, you may use software to regulate fans on laptops and desktop computers. This free software provides you with an extraordinary level of control over your fans. It enables you to select how fast they spin at different temperatures depending on your needs.

They provide you with the ability to regulate individual fan speeds with knobs or other controls. But the drawback is that most of these controllers are entirely manual and do not automatically alter fan speeds in response to temperature changes.

4. Making Use of the Control Panel

You may also alter the fan speed of your computer’s CPU via the ‘control panel’ on the computer. Take the actions outlined below:

  1. Press the Windows key and enter the “control panel” into the search box. When you see it in the search menu, click on it to open it.
  2. Select the ‘Performance and Maintenance’ area from the drop-down menu.
  3. Select the ‘Power Saver option from the drop-down menu that appears. 
  4. The brightness, CPU processing, cooling technique, and other settings will all be available for you to choose from. The ‘Cooling Method’ option is what we are searching for in this case.
  5. In that choice, you can see the slider bar at the bottom. The fan speed of the CPU will increase in direct proportion to the bar setting. You may adjust the position of this slider bar to raise or reduce the fan speed as needed.
  6. After you’ve made your adjustments, click on the ‘Ok’ button.

How Do I Adjust My CPU Fan Speed Windows 10?

To adjust the fan speed on Windows 10, you must do it at your discretion and at risk. Keep in mind that if your computer or laptop overheats, you risk permanently damaging hardware.

You will need to download third-party software to be able to adjust the fan speed. The app that you use depends on the hardware that you have. In theory, you should locate an app that can detect your fans and enable you to control their speed.

Speed Fan is one of the free programs that allow you to have more sophisticated control over the fans on your computer’s processor. SpeedFan has been around for a long time, and it is still the most commonly used tool for fan management in the computer industry today.

Despite its widespread popularity, SpeedFan is a little more challenging to use for novices. When using this program, exercise care since if you make a mistake, it may cause harm to your hardware.


When you are working on your computer system, the continuous hum of fans may be a source of distraction. When you’re playing video games, it may even get irritating. As a result, it is beneficial to regulate the speed of the CPU fans in the computer. Controlling the fan speed of your CPU will assist you in extending the life of your system by ensuring that it is in excellent working order at all times.
