Strange things start happening as the temperature of the processor and other components rises. First we need to know what is producing heat in our computer. The main sources for heat in the computer are the processor and the power supply. The other thing we need to know is that we are using air to cool the components in the computer. Restrict the air flow and we make the heat build up.
Air cooling systems rely on heat sinks to pull the heat away from components.
Most heat sinks for Pentium and Pentium II processors include fans to provide additional cooling. The power supply is the next source of heat in the computer. It is the most often overlooked source for overheating problems. Power supplies come in many different price ranges and designs. I did a great deal of research on the motherboard, processor, video card, sound card and network adapter, but neglected the power supply.
