Cpu Coolers

It may seem surprising how much heat a tiny little computer processor can generate. When you look at how much power goes into a CPU, however, and how much processing actually takes place inside that tiny chip, the heat output begins to make a little more sense. CPU coolers are a crucial component that keep your processor cool and allow it perform at a constant reliable level.

How CPU Coolers Work

CPU coolers are designed to extract heat from the processor as quickly and efficiently as possible. Without a CPU cooler your processor would quickly overheat during even the most basic processing tasks, which could quickly damage the processor and render it non-functional. So how do CPU coolers manage to get all that heat out so quickly?

CPU coolers are mounted directly to the processor on your motherboard, usually by using a type of thermal grease or a sticky heatsink pad. This material is highly conductive and sticks directly onto the top of the processor, allowing heat to move straight out of the processor and into the heatsink above. The thermal material is extremely sensitive, and even a small hair or a bit of dust can keep it from doing its job properly.

Above the thermal material, you'll usually find something called a heatsink, which is basically a piece of conductive metal built in a sort of fan shape. The maximized surface area on the heatsink allows the heat from below to transfer into the air around the processor. This heated air is then sucked up by a fan that is mounted on top of the heatsink. The fan blows the hot air into the PC case, and the case fan then draws the hot air out of the case completely.
