How to Control the CPU Fan on Windows 11. A PC’s CPU fan is essential to keeping the computer cool under load, but Windows does not provide tools for changing CPU fan speed. This article will teach you how to control the CPU Fan on Windows 11.
What are the things I must know about fan control in Windows 11?
While the built-in settings should work just fine to keep the system temperature in check, you may need to sometimes manually control the fan in Windows 11.
When doing so, you can set it to the desired value for optimal results. For instance, during operations that consume a lot of resources, the speed can be changed to high while if you are just scrolling through the web, keeping it low should be fine.
Also, when the fan runs at full throttle, it will produce a lot more noise and cause discomfort than somewhere near the mid-range. You will have to consider this factor as well when using the manual fan control approach in Windows 11.
- Windows 11 doesn’t offer a built-in tool for monitoring or controlling CPU fan speed.
- You can control CPU fan speed with software or your PC’s BIOS.
- Never set the fan speed to 0. This may cause your CPU to overheat.
Here is How to Control the CPU Fan on Windows 11
Windows 11 doesn’t provide built-in tools for monitoring or customizing CPU fan speed. You must turn to one of three alternative methods to control the CPU fan on Windows 11.
We recommend using first-party software. This isn’t possible for every Windows 11 PC, however, so we’ll cover all three options.
- Use first-party software. Modern computers are often compatible with proprietary software to lets you change the CPU fan speed. This is the quickest, easiest solution, but you must download the correct software.
- Use BIOS. Most PCs ship with a BIOS which can display the current speed of your CPU fan, while more feature-rich BIOS will let you change the fan speed. You can accomplish this without downloading software, but it can be complex.
- Use a third-party utility. Third-party utilities are capable of detecting the speed of your CPU fan. A few even let you change it. These utilities work on a wide variety of hardware, but you may encounter bugs and compatibility issues.
Never set CPU fan speed to 0. Most CPUs are not designed to operate without active cooling and will overheat. Damage can occur when the fan is at 0.
How to Control the CPU Fan With First-Party Software
First-party software is developed by your PC manufacturer, or the manufacturer of your PC’s motherboard, for use with specific hardware. It will work without compatibility issues and is often the least difficult to use.
Determine the manufacturer and model of your Windows 11 PC. If your Windows 11 PC is a custom build, then determine the manufacturer and model of your PC’s motherboard.
Having trouble finding the manufacturer and model of your PC? Look for a serial number printed on the bottom or rear of the computer. If you can’t find a label, try downloading a free system information tool.
- Visit the support site maintained by the manufacturer of your PC and search for your PC model. Many sites also let you search by serial number or even a purchase number, if you have it.
- Open the downloads section on the support page dedicated to the model of your PC and look for its system utility. Download the utility.
Most PC manufacturers bundle fan control into a system control or overclocking utility. Common examples include Alienware Command Center, Asus AI Suite, and MSI Afterburner.
- Install and open the utility and look for fan speed control. For example, opening Settings in MSI Afterburner’s menu and selecting the Fan tab will display fan control options.
Most software displays fan speed settings as a percentage of maximum. A value of 100 is the fan’s highest setting, while a value of 0 is the lowest. Higher fan settings cool better but are louder, while lower settings offer less cooling but create less noise.
How to Control the CPU Fan With BIOS
BIOS is the rudimentary operating system on your PC’s motherboard. The BIOS software starts when you turn on the PC. Most BIOS let you view or customize CPU fan speed.
Shut down your computer.
Once the shut down is complete, turn the computer back on and then immediately tap the shortcut that launches BIOS settings on your PC. This can differ between PCs, but most accept the F2, F12, or Delete keys.
Look for a menu option that displays fan settings. This differs between motherboards, but it’s often shown under PC Health, Advanced, or Overclocking. If you’re lucky, fan speed settings may already be visible on the first menu shown.
BIOS will typically express fan speed settings as a percentage of maximum. A value of 100 is the fan’s highest setting, while a value of 0 is the lowest. Change the settings as desired, then save and exit.
How to Control the CPU Fan With Third-Party Software
Third-party software is developed by a party other than the manufacturer of your PC. It has the benefit of working on a wide range of PCs, but you’re more likely to encounter it not working perfectly (it could run just fine, of course).
Download and install third-party fan control software. Popular options include SpeedFan, Argus Monitor, and Fan Control.
Open the software. Look for Fan or Fan Control. Fan speed will typically be shown as a value between 100 and 0, where a value of 100 is the fan’s highest setting, while a value of 0 is the lowest. Change the settings as desired, then save and exit.
Why Can’t I Control My CPU Fan on Windows 11?
If you try all three methods above, yet none work, it’s possible your PC doesn’t allow CPU fan speed control. It might be blocked by the system BIOS, which is sometimes true of laptops, or your CPU fan might not be connected with a motherboard fan connector that allows fan speed control.
To control your CPU fan on Windows 10, try a third-party tool such as Speedfan. After you download Speedfan, select Automatic fan speed to have Speedfan automatically control your system, or choose Configure > Advanced, then find your fan and set it to Manual. Once it’s set to Manual, go back to the main page and adjust your fan speed level up or down.
Fans that are toward the PC case’s front are likely intake fans; they take cooler air in to help lower the case’s temperature. Fans located at the back are typically exhaust fans; they expel the air that’s been warmed up by the computer’s components.
Make sure the processor is visible, and remove any duct or other impediment. Find the power cable connecting the fan to the motherboard, then carefully disconnect this power wire. Find the clip connecting the fan to the processor, then gently press down with a screwdriver or similar tool until the fan unlatches. Finally, remove the heat sink from the processor.
Your CPU fan may be loud because it’s bogged down with dust and dirt. To solve the problem, use a can of compressed air to remove the debris. Also, make sure to place your computer in a well-ventilated area so the fans don’t become overworked, and consider a cooling pad for your laptop.
Can I turn off the computer fan to reduce noise in Windows 11?
You should never turn off the computer fan or set its speed too low since it wouldn’t be able to cool down the system.
Whenever you run a bunch of apps or there are major processes in the background, your computer may heat up and the need to reduce overheating will arise. This is where the computer fan comes into the picture.
If the temperature inside the system reaches close to 95° C, the chances of damage to delicate components are high. Hence, it’s recommended that you either let the computer choose the optimal fan speed or set it to normal levels when following the manual approach.
What can I do if the fan is always running in Windows 11?
The fan starts functioning when the temperature inside the system is to be brought down to optimal level. In case the computer fan is always running, it indicates a constant overheating.
If you are running high-end applications or perform multiple tasks at once, try eliminating those. When the problem persists, it’s the dust build-up to blame.
In case of severe dust build-up inside the vents, the hot air from the inside cannot escape which leads to an increase in temperature, thereby prompting the computer fan to start functioning. And, since the fan is unable to bring down the temperature to optimal levels, it keeps running.
That’s all there to know about PC fan control in Windows 11. Before you take control and start making modifications to the fan speed, do thorough research to understand the required settings.
