Clifford T Johnson, P.E., CSE
The course will answer several questions that bother anyone who specify, use or assemble their own present day personal or industrial computers. It will answer the question, why does a computer need that noisy fan(s), how hot can the CPU (Central Processing Unit) get without causing a problem, where can I find the best solution. The course will even show you how to assembly a very simple solution to the fan noise.
This is a 2-hour course and will cover the following:
1. Why Heatsinks are required and how they work.
2. Other types of CPU cooling devices.
3. Calculations for heat dissipation.
4. Specifications for most CPUs including temperature limits.
5. Thermal compounds, types and use.
6. The physical effects of a heatsink.
7. Heatsink Technology: Radiation, Conduction, and Convection.
8. Heatsink testing methodology and comparisons.
9. The Listening Room: hear and compare the sounds made by cooling fans.
10. Instructions for assembling a simple fan controller.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
