Solve the CPU fan error problem

This situation is rarely encountered in small series, many users mentioned that each boot prompt "CPU FAN ERROR PRESS F1 TO RESUME", "CPU fan error, this How to solve the problem?

1, the system BIOS can not detect the speed of the CPU fan

After booting, press Del to enter the BIOS option, enter Power→ Hardware monitor, you will see three together The difference is CPU FAN SPEED; CHASSIS FANSPEED; POWER FAN SPEED, the first item is changed to IGNORED, the second item is changed to N/A, and the third item is changed to IGNORED.

2, the fan is not working properly or the speed is too low

The fan works too long, the inside of the lubricant is dry, causing the fan speed to slow down, adding some lubricant inside the fan. Increasing the fan speed will reduce the temperature inside your chassis so that it does not burn out the CPU.

3, the fan power cable is wrong

Generally there are multiple fan sockets on the motherboard, the CPU fan should be inserted in the "CPU_F", above, if not inserted here though The fan is normal, but the motherboard will prompt an error. Insert the power plug of the CPU fan into the corresponding position, and the general problem can be solved.

4, the motherboard battery is dead

Remove the COMS battery on the motherboard, and then wait a few minutes to install it back, you can restore the motherboard COMS discharge default; finally use in the BIOS default setting.

The above points are the reason and solution for the prompt of "CPU fan error" when booting up. The silicone between the CPU and the fan is gone, causing the heat to not be emitted, and too much dust inside the chassis will cause the boot. A prompt for "CPU fan error" appears.

This question is about to start from these four points. If you exclude one item, you can share it. If there are other reasons, you can share it.
