Cooling Systems
PCs generate a lot of heat – the CPU, hard drive, video card, processing chips, etc. put out a ton of heat in a small enclosed space. The computer system must properly maintain a reasonable temperature or things could – literally – melt down. There are several different type of cooling systems available for PCs with two primary methods: air and liquid.

The most common cooling method is a series of fans designed to blow heat away from heatsinks on the CPU and video cards – the two biggest heat generators in the system.

A heatsink is designed to disperse the tremendous amount of heat generated on chips in a system. Typically, a heatsink has a fan attached to it to blow the heat away from the CPU and allow it to maintain a reasonable temperature.
Liquid Cooling Systems
A technology which is currently used by high end computer systems is liquid cooling.

Liquid cooling uses water or another liquid to cool the system and maintain proper temperatures.

I'm old school, from back in the 5 1/4 floppy days, LOL. I still have them. Thanks. I give this lesson two snaps and an A+.
... If you want to upgrade your computer to dual processors, you must reinstall Windows as the HAL is based on the number of processors you have in your machine. May someone please answer this for me? I've heard of HCL but not HAL.
