Homework Help: Questions and Answers: What is the purpose of thermal paste in a computer system?
A. To hold components together
B. To clean the CPU
C. To improve heat transfer between the CPU and heatsink
D. To increase processor speed
Answer:
First, let’s understand the Role of Thermal Paste:
The CPU (Central Processing Unit) generates a lot of heat during operation. The heatsink is a metal device that is designed to dissipate this heat away from the CPU.
When the heatsink is placed on the CPU, there can be tiny air gaps between the surfaces due to imperfections. Air is a poor conductor of heat, so these gaps can hinder efficient heat transfer.
Purpose of Thermal Paste:
- Thermal paste is applied between the CPU and the heatsink to fill these gaps.
- It ensures that there is maximum contact between the CPU and the heatsink, which improves heat transfer from the CPU to the heatsink.
- This helps maintain lower CPU temperatures, which is crucial for the performance and longevity of the computer.
Given Options: Step by Step Answering
a) To hold components together
- Thermal paste is not an adhesive; it does not hold components together.
b) To clean the CPU
- Thermal paste is not used for cleaning.
c) To improve heat transfer between the CPU and heatsink
- This is the exact purpose. It enhances thermal conductivity between components
d) To increase processor speed
- While better heat management can indirectly prevent thermal throttling, thermal paste itself does not increase processor speed.
Final Answer:
Based on the above analysis, the correct answer is:
C. To improve heat transfer between the CPU and heatsink.
This is correct because thermal paste’s sole purpose is to improve thermal conductivity between the CPU and heatsink, ensuring efficient heat dissipation from the processor.
