What is CPU fan error and how to fix this ? easy methods 2021

CPU fan error is a common error message. It is usually displayed when starting a Windows-powered desktop or laptop. The alert message appears on the screen after the computer is turned off due to excessive heat. This happens only when the CPU fan is unable to cool the computer’s hardware adequately.

CPU error message and forced shutdown are disappointing for you, it indicates that the computer’s security system is working properly. Several hardware components can suffer permanent damage if fans do not work properly and the computer is overheating.

There are ways to confirm the cause of overheating and the resulting error message, as well as ways to fix them.

What is the reason for CPU fan error?

A CPU fan error in the start-up is usually due to physical damage to the fan, incorrect settings or some external factors. As a result the computer overheats and makes the fan run at an abnormally high speed. Again dust or other objects inhibit the air vent of the device can also cause CPU fan error.

Why do you get a CPU fan error?

There are several reasons why computer users in general receive fan error messages CPU related to them. To solve your computer fan problem, you need to know the reasons first. Why are you getting such error problems. E.g.:

  • Incorrect setting of fan information in  BIOS interface.

First it is important to know if you accidentally or intentionally opened the interface BIOS reset CPU fan information before receiving this fan error warning message? In fact, in everyday use, your computer cannot detect connected CPU fans or detect fan speed at all. Because fan settings have not been changed correctly.
In this case, you must first change the fan settings.

  • Your CPU fan is not connected properly

You need to be sure you connect your PC’s CPU fans properly? If you have dropped/started your computer or recently connected your CPU fans to lose an error or connection, you may get stuck in the problem of such CPU fan failure. Because it happens if CPU fan is not connected to it properly. So reconnect the CPU fan to get a solution.

  • Processor fan is moving very slowly due to dust or poor quality.

Usually, relevant CPU fan error messages come to computer users when CPU fan moves too slowly or even stops working. Because fans are blocked by dust or the fan is of very low quality as a result of prolonged use. What you need to do is: check and clean your CPU fans regularly. And if you see that the fan is inferior then we would suggest that you change it to a good quality CPU fan.

  • CPU fan damaged or broken, causing problems with overheating of PCs.

If you are sure that the fan problem concerned is not caused by the above factors, you may have to see if you have any health problems with the CPU fan.

For example, if your fans are really damaged or broken and can’t work completely properly, a message of such a CPU fan error must appear on your computer’s start screen. This will help you avoid problems like getting more severe overheating. (Such as your computer sudden lying frozen, unexpected computer failures, slow computer operations, and more. )

In general, no matter what the reason for your case is the tie, don’t think in the first place that your CPU fans have to be replaced with new ones. Try the methods below first, hopefully you can solve your error from these solutions. You can replace it with a new one if your fan is not fixed after that.

How to fix a CPU fan error?

CPU fan errors can be caused by both hardware and software problems. So the solutions to the errors are equally diverse. And it requires checking the specific settings and internal CPU fan.

Follow these tips to avoid overheating and error messages CPU.

  1. Clear air vent.

Air vents have to be cleaned. The easiest way to do this is to use it at full strength after removing the brush from your vacuum cleaner. It can suck any dust and debris. Alternatively, you can use an airgun or canned air to blow out the dust.

2. Remove your computer.

If you accidentally leave your computer in a lot of heat or sunlight, it will overheat and may turn off. No matter how well the fan works in that. So try to take your computer to a relatively cold room or make sure it is not directly in sunlight all day.

3. Clean CPU fan.

For this task, you need to turn off your computer and unplug it from the source of the power and open the case. Once opened, you can clean the interior. For this, you can remove dust with an airgun or canned air. Or you can also use vacuum cleaners.

Clean CPU fan

Remember that no cleaning agent can be sprayed on any part. Because most cleaning agents based water. So spraying it can cause serious damage to the internal parts of the computer.

(Mentioned that many devices, such as microsoft surface line of products, etc., are not designed to open. If you remove it somehow, the warranty of the device may be cancelled or caused permanent damage. So in these cases, specify the official support manual of your device or call customer service. )

4. Stop overclocking.

Overclocking causes a fatal damage to the computer. The result is a dramatic increase in the heat of the system. Which cannot be managed by the default fan in any way. This can cause permanent damage to the circuit and cause frequent shutdowns and errors such as overheating.

5. Check your CPU fan.

When your computer is on, check your device’s internals thoroughly to make sure that it’s not loose or knocked out of place. Depending on your fan model, you’ll be able to re-position your fans with a screw driver or glue.

(Whenever you’re checking something inside an electric device, make sure it’s completely turned off and disconnected from all energy sources. You must shut down when turning off your computer. Never choose sleep mode.)

6. Check the location of your CPU fan.

If you have installed CPU fan yourself, make sure it is installed in the right place. It must be connected to the CPU header of the motherboard. The fan can run when the computer is turned on even if you accidentally attach it elsewhere. It will not cool the CPU adequately unless connected to motherbird’s CPU header, which is its main purpose.

(The CPU header is likely to be labeled “CPU Fan”. But if it doesn’t, it will be connected to three holes for the fan’s three-way plug. )

7. Try an alternative CPU fan header.

Sometimes there are multiple CPU fan headers on the motherboard. Now if the previous CPU fan header is drought, try plugging the fan into a different slot. If the fan header is bad, the CPU fan will definitely add errors and show erron messages. So even if connected to another header, the CPU fan error is fixed.

8. Change BIOS settings.

If you see your CPU fan working properly and you are sure your computer is not overheating or overheating, this change in this step BIOS setting may bypass the CPU fan error message. Your device can be turned on correctly again.

To do this,
>Open BIOS first and select monitor.
Click on > Fan Speed Monitor.
> N/A
Save > changes

(This may affect your computer’s ability to detect CPU fans and overheating problems in the future. It is recommended only for those who have tested it to ensure that their CPU fan is working properly and that it is cooling down enough hardware. )

9. Check CPU fan settings in BIOS.

This solution can sometimes be used to solve technical issues and ensure everything is as it should be.

Open BIOS first,
Then advanced settings,
> Hardware Monitor,
Select > CPU fan.
Enable active hit sync and fan duct with >fan.
Disable passive hit sync and fan duct without fan.
Save your changes and exit BIOS.

You will often be asked to press F1 when you receive the initial CPU error message. When this message is visible, F1 will open BIOSও even if you are still on the tip.

10. Replace CPU fan.

If none of the above works, your fan may have become useless if it’s not broken. So the latest solution may need to be replaced. If your computer warranty is in period, it can cover free fan repairs. If you bought the fan separately, it may have its own warranty. You can also use it to get a free or discounted replacement part.

Hardware problem Solving

Before starting, you start the job only if you are confident enough to open the computer and test the operation of the fans yourself. If you do not have basic knowledge of hardware, we recommend that you take your system to a local technologist and check it. Now, follow these step-by-step instructions to visit your fan for physical damage.

1. Turn off your computer, then move the processor case glass to check the fans connected to the motherboard.

2. Then make sure that there is no loose wire and all wires are properly connected for each fan.

3.After that, turn on power to the system and do not put the glass back in place. Be careful to make sure fans are not spinning properly.

4. If you notice that wires are properly connected, a fan is not rotating. Then it means the fan has been damaged and must be replaced.

5. If all fans work properly, be unconcerned. Your CPU fans do not appear to have been physically damaged and the error message appears to have been caused by a software error.

Software Problem Solving

If you have seen hardware diagnostics and fans seem to be working properly, this means that the problem is caused by a software error. Follow the instructions below to resolve the problem:

1. Turn on the computer and enter BIOS settings by pressing the F10 key.

(N.B: This F10 key ti may vary depending on different manufacturers so there may not be F10 in all cases, you can take the help of the Internet to be sure).

2.Now go to fan control section. You can usually find it on hardware monitors. Whatever is under advanced settings in BIOS. It can only be in a separate tab on other PCs.

3.There, make sure that the CPU’s Q-Fan control option is activated.

4. After this, you can set low speed limit for CPU fan. Set this option to ignore and reboot your system.

5. See if it solves your problem.
