What's going on with "CPU fan error" On the boot?

Every boot prompt "CPU fan error press F1 to RESUME", "CPU fan error" is what it means, not the CPU, but the auxiliary CPU fan out of the problem, what causes the system prompt "CPU fan error", if the CPU Fan error "prompt. Here's a look at the causes and workarounds for CPU fan error on boot.

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

Press Del to enter BIOS option after power on, enter Power→hardware Monitor, you will see that there are three of the CPU FAN speed, respectively; CHASSIS Fanspeed; POWER FAN speed, change the first item to ignored, the second to N/A, and the third to ignored.

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

The fan has been working too long, the lubricating oil inside is dry, causing the fan speed to slow down, add lubricating oil inside the fan, increase the fan speed will reduce the temperature inside the chassis, so that the CPU will not burn out.

3, the fan power cord connected wrong

The general motherboard has a plurality of fan sockets, the CPU fan should be inserted in the "Cpu_f" this above, if not plugged in here although the fan is normal, but the motherboard will prompt error. The general problem can be solved by plugging the power plug of the CPU fan into the corresponding position.
