2, it is possible that the system BIOS can not detect the speed of the CPU fan

Methods: 1, in the computer boot press del into the BIOS interface, and then into Powerhardware Monitor, and then here will see the CPU FAN SPEED; Chassis fanspeed; Power FAN speed Three options to change the first item to ignored, the second to N/A, and the third to ignored, then save to exit.

3, may be the fan power cord connected to the wrong

We all know that the general motherboard has more than one fan socket, 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 be prompted to error, method: The CPU fan power plug into the corresponding position, generally can solve the problem.
