Fan failure is generally divided into two kinds:
1: A fan error occurred in the computer
This must be the machine fan failure, according to the general fault processing procedures, the treatment method of this problem is to replace the whole fan cooling group (fan core and associated heat sink) can solve the fan error(fan error) not into the system.
2: The laptop fan is running, but the laptop is very hot, it just doesn't cool down.
In fact, the computer fan is not broken, the reason is the heat conduction tube, so we must replace the heat conduction tube, so as not to burn out the CPU or motherboard
