When replacing the CPU in a laptop, which of the following locations should have thermal grease
applied?

A.
Connection points on the system board

B.
Bottom of the CPU

C.
Top of the CPU

D.
Axis of the cooling fan

Explanation:

Thermal grease should always be applied to the top of the CPU. The smooth surface is the top not
the one with the pins. The pins go into the socket whereas the heat sink is placed on top of the
CPU. Between the heat sink and the cpu, apply the grease for maximum thermal dissipation.
