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

Correct Answer: C

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.
