Installing a new CPU, what is applied directly to the CPU?
- A.
Cooling liquid
- B.
Thermal compound
- C.
A heat sink
- D.
A fan
Correct Answer
B. Thermal compoundExplanation
When installing a new CPU, thermal compound is applied directly to the CPU. Thermal compound is a substance that helps to improve the transfer of heat between the CPU and the heat sink. It fills in any gaps or imperfections on the surface of the CPU and helps to ensure that heat is efficiently conducted away from the CPU. This helps to prevent overheating and ensures optimal performance of the CPU.Rate this question:
