What Causes the CPU Fan Error?

Starting up a Windows desktop or laptop and getting an error warning about the CPU fan is usual. The notice typically appears after a computer has shut down because of excessive heat. It can happen if the fan isn’t powerful enough to keep the hardware cool. Forced shutdown and CPU fan error warnings are annoying, but they show that the computer’s security measures are in place and working effectively.

What Causes the CPU Fan Error?

The CPU fan problem typically appears when a Windows PC powers up or starts up. It doesn’t pop up while Windows is functioning correctly. The following is an example of an error code message:

  • “CPU Fan Failed Error:”
  • Fan Error on the Computer: “CPU”
  • Errors in the CPU Fan Driver:

Errors with the CPU fan are most often caused by:

There are various reasons why a car’s CPU fan won’t turn on, but three of the most common include an injury, wrong fan settings, or events outside the computer’s control. Dust accumulating in the phone’s air vents can cause issues with CPU fan error.


Overheating is a problem for CPUs with faulty cooling. Nevertheless, if the computer’s safeguards are ineffective or do not take effect quickly enough, the CPU may operate at temperatures greater than its safe limit and eventually fail. CPUs can overheat to the point of igniting, resulting in permanent damage.

What to Do If Your Ceiling Fan Dies?

If the CPU fan stops working, turn the computer off right away to avoid any further hardware damage. When a normal system shutdown isn’t fast enough, try holding down the power button or yanking on the cord instead. Hard shutdowns can damage data, but even if the system is left on for a short period to go down usually, the computer runs the great danger of being destroyed.

Defending against the Attacks of AMD and Intel:

In a CPU failure, both Intel and AMD CPUs will issue error messages and attempt to shut down. CPUs from Intel will reduce their clock speed if the temperature becomes too high. In the event of a CPU cooling failure, these CPU defense systems are intended to keep the machine from going ultimately nuts. If you restart the computer, an error notice will appear, and the power will be shut off to the CPU to prevent harm.


The computer should not use again until a working cooling unit has been installed if the CPU cooling fan has failed. It’s common practice to replace the cooling unit as a whole when the fan malfunctions. A new cooling unit also necessitates the replacement of the thermal cooling compound that serves as a physical link between the heat sink and the CPU. New cooling units can be installed by the customer or by a professional. Incorrect cooling unit installation might potentially result in a CPU malfunction.

Errors Associated With The CPU Fan:

Solutions abound so when CPU fan stops working, ranging from testing specific settings to completely replacing the CPU fan. Hardware and software problems both play a role in CPU fan failures. You may avoid error messages and keep your car’s CPU cool by following these tips.

Do a new location switch for your computer:

Leave your computer in direct sunlight or heat, even if the fan is working hard, and it will overheat and shut down. Place your laptop in a shady spot or keep it out of direct sunlight during the day.

Put an end to your computer overclocking:

The increased system temperature is a common side effect of overclocking, and the built-in fans can’t keep up. It’s possible to damage circuits, resulting in frequent shutdowns and overheating problems.

Make sure the vents are clean:

The hoover brush can remove dust and debris from vents by simply removing the meeting and using the vacuum cleaner at full power to clean them out. Compressed air or even an air pistol can also use to remove dust.

Hardware Troubleshooting:

Before you begin, make sure you have the self-confidence to remove the computer’s case and inspect the fans for operation. If you don’t know how to accomplish this, we suggest hiring a local specialist to perform it for you. Please follow these steps to ensure your fan is free of physical harm before using it again.

Step 1: Disconnect the motherboard from the CPU case and look for the fans attached to the board.

Step 2: If there are any loose cables, double-check that they are all connected correctly before moving on.

Step 3: After that, turn on the system’s power without putting the glass back on. Always keep an eye out for a fan that is spinning.

Step 4: Check that the connections are correctly connected if you discover a non-spinning fan. It suggests the fan is damaged and has to be replaced.

Step 5: Congratulations if all of the fans function correctly. Neither your fans nor the error message is physically damaged. Therefore it’s likely a software issue.

Troubleshooting Software:

Hardware diagnostics show that the fans are working correctly; hence the issue is most likely a software one. To fix the problem, follow the steps listed below:

Step 1: Press the F10 key to open BIOS settings. After turning on the machine, the key may vary depending on the manufacturer.

Step 2: Next, head over to the fan settings page. Some BIOSes contain Hardware Monitor under Advanced Settings, while others have a dedicated tab for this feature.

Step 3: Check to see if the Q-Fan control option on the CPU is enabled.

Step 4: After that, you’ll see the CPU fan’s reduced speed restriction. Reboot your computer after selecting ignore and then selecting this option.

Step 5: To see if this has helped, go ahead and try.

If the problem remains despite your efforts to resolve it, you may have to get your computer’s CPU fan replaced. CPU temperature regulation is essential to computer performance. Thus any CPU fan error that repeatedly appears while booting up your laptop indicates something is amiss and should be investigated immediately. The actions outlined above should have helped you figure out how to resolve this issue. cpu fan error, cpu fan error.
