How to Fix CPU Fan Error on Windows

CPU Fan error generally occurs when your Windows enabled computer boots up, and it is a pretty common message on Windows computer. When your device automatically turns off due to overheating, then this error may appear on your screen. In these cases, mostly, the CPU overheats on a rate at which the cooling fan fails to provide sufficient cooling.

If you see this error, then it means all useful safety components are working properly on your computer. In case your CPU fan stops working, and all safety systems of your computer stop, then your CPU components can be damaged. You might need to replace your processor, or even the whole motherboard if the computer cooling system stops working. In this article, we are going to fix the CPU fan error on a Windows computer. If you are facing the CPU fan error on the Windows startup screen, then you have come to the right place. 
Ways to Fix CPU Fan Error Message 
Hardware and software glitches and failure can cause the CPU fan error. The solutions for the error may vary as some include software troubleshooting, and some include hardware troubleshooting methods. Here are the best methods to solve the CPU fan error:
Method 1: Changing the Placement of Computer
The first and most effective method is to move your device to a cooler place. If the CPU or your laptop is placed near or in the direct sunlight, then it can cause overheating in your device, regardless of your CPU fan working or not. Your CPU fan can’t cool down your device if it is receiving heat directly from the sunlight or any external source other than your CPU itself. So before diving into the in-depth troubleshoot, make sure to keep your device in a cooler place.
Method 2: Avoid CPU Overclocking   
The CPU overclocking increases the excessive load on your processor as well as on the motherboard. The excessive load on your CPU processor can result in overheating of your processor and other CPU components. Your CPU fan is not capable of cooling down the CPU, which is constantly receiving overload and overheat. Make sure to pursue limited tasks at once and don’t use the programs that consume high CPU usage.
Method 3: Cleaning the CPU Air Vents 
Make sure that all air vents are clean and free from any debris. The air vents should be nicely cleaned so that the CPU can breathe. Your CPU fan actually needs to inhale cool air from the one side vent, and from other, it exhales the hot air. If the air vents of your laptop or CPU get clogged with dust, then your fan will not be able to cool down the CPU efficiently. You can use a vacuumed cleaner to pull out all dust from the CPU vents. You can also use a blower to blow away all the dust and debris from the air vents. 
Method 4: Cleaning the CPU Fans
Turn off the CPU and then plug out all of the connected cables to it. Now open the CPU to clean the CPU fan inside it. You can either use a blower or air gun to clean the CPU fan gently. By doing so, your fan will be able to move more freely and inhale and exhale more air. As a result, your CPU fan error would vanish away from the start-up screen. 
Method 5: Check the CPU Fan 
Once you have done the cleaning, make sure that the fan is not loosened from its grip. Also, ensure if the fan as been fallen from its original place as it can happen if your CPU has received any physical damage or shock. This can cause insufficient cooling in the CPU region. If the CPU fan seems to be fallen out of the original place, then try to fix it back on its desired place by using glue or screws. 
Method 6: Use Another CPU Fan Header  
If your computer has more than one CPU header, then make sure to change the fan header. You can do that by plugging your CPU fan to another slot of your motherboard. Please avoid this method if you are not technically skilled or experienced. 
Method 7: Check BIOS Settings for the CPU Fan 
The CPU fan BIOS settings can affect the cooling effects and the speed and running time of the fan. Here are the settings that you should check and tweak accordingly: 
  1. Get into the BIOS mode of your computer. 
  2. Once the BIOS is opened, make sure to head to the Advanced Settings. 
  3. Now go to Hardware Monitor
  4. After that, select the CPU Fan option. 
  5. Now turn on the Active Heat Sink option. 
  6. Also, enable the Fan Duct with Fan option. 
  7. Ensure that the Passive Heat Sink option is disabled. 
  8. Now once that done, turn off the Fan Duct without Fan option. 
  9. Save the changes. 
  10. Exit from the BIOS menu.
