The CPU is the largest heating device on the computer. When you start the computer, you will see “CPU fan error”. When you see this, the CPU is most likely to have a high temperature due to a fan failure.
Does your computer display “CPU fan error” when starting up? You may get stuck in the next step to correct the problem. This error may be triggered after the computer shuts down due to overheating. The CPU fan may no longer be able to cool the computer hardware.
If you do not solve the problem immediately, it may adversely affect other computer hardware components. Or, the error may be caused by physical damage to the fan, incorrect settings, or other factors (such as dust).
These are the various methods you can use to solve the CPU fan error immediately. They are easy to do, and you should develop a habit to make sure you don’t make mistakes again.
Method 1: Check the fan wiring
The first thing you need to do is to check the fan wiring. The CPU fan is connected to the motherboard or power supply. When the wiring is loose, the fan does not energize.
You need to correct this to make sure it is strong and tightly connected. Check that all fan connections are properly secured.
Another option is to plug the CPU fan header into another port. The power port on the motherboard may be malfunctioning, so you need to use another one.
Method 2: Clean the CPU fan
After the fan is used for a long time, dust will accumulate. The lubricating oil in the bearing will be reduced, causing the fan to fail to rotate when it is turned on.
step 1: To solve this problem, you need to open the computer hardware shell. Then use your fingers or a flat-head screwdriver to turn the CPU fan push pins 90 degrees counterclockwise to loosen them. This action will help loosen the fan.
Step 2: Remove the fan connector from the fan header. Loosen any type of wiring and remove the CPU fan from the heat sink.
Step 3: Clean the radiator with running water and a brush. If the oxide layer is very thick, sand it with 800 GRIT sandpaper. Use it on the radiator until it is completely clean. Make sure it is completely dry before repairing.
Step 5: Take out the CPU fan and use a dry brush to remove dust. Then gently wipe the CPU fan with isopropyl alcohol. Even the connecting wires are cleaned.
Step 6: Install the CPU fan on the heat sink, just like removing it. Dip the paper towel in isopropyl alcohol and gently remove the thermal grease/heat sink compound from the processor.
Step 7: Use isopropyl alcohol to gently clean the CPU cooler. Take thermal paste or thermal paste, pour the paste into the center of the heat sink, and then spread it out. Make sure that no gaps are left during the process of applying thermal paste.
Step 8: Rotate the pushpin 90 degrees clockwise to reset it. Press the push-in pieces to insert them back to secure them. Insert the fan connector, put the power cord back in the correct position, and then turn on the computer.
Method 3: Disable CPU fan speed monitoring in BIOS
If the fan malfunctions, it may cause the following text “CPU fan error” to appear on the screen when starting up.
step 1: To solve this problem, first press F2 or F12 to enter the motherboard BIOS during startup.
Step 2: Press F7 on the boot menu or click Advanced mode Options in the lower right corner.
Step 3: On the next page, click Monitor Options. In the CPU fan speed, select “N/A” and change to “Ignore”.
Step 4: Press F10, click save Row, And exit.
Step 5: Restart the computer.
Method 4: Buy a new CPU cooler
When the fan motor is damaged, it is recommended that you buy a new one from Amazon. Another option is to buy a new CPU cooler. This will help the heat circulation in the computer. If the radiator is completely damaged, it will prevent your computer from working properly. The type of heat sink you buy depends on your computer model.
Method 5: Stop overclocking
When the CPU fan cannot be controlled, the increase in system heat may cause overclocking. This can cause circuit damage and frequent shutdowns. If the problem is serious, you can replace the CPU fan if it is damaged and needs to be replaced.
Please regularly maintain the CPU cooling fan and other components. It is recommended that you clean it every six months to help extend its service life. There are several CPU-related errors and you need to be cautious to ensure that your computer is always running well.
If the connection is normal, please clean the CPU fan, disable the CPU fan speed monitoring, or buy a new CPU cooler. In all these methods, you will find a way to solve your computer problem. If a particular location is dusty, you can move the computer to another location.
