ASUS VivoBook S400C CPU Fan Replacement

简介

The CPU fan blows cool air across the fins of the heatsink to remove the heat generated by the processor from the computer.

Since the fan runs at all times when the computer is turned on, it is expected that it may eventually fail. The fan's lifetime can be extended by an occasional cleaning.

Carefully remove the old thermal paste from the CPU. It is not vital to get the old paste off the parts of the chip under the Kapton tape, but be obsessive about cleaning the silicon chip itself and the area immediately next to it.
