Why do you need heatsinks?

Because of the super fast calculations and speeds that are being achieved by today’s processors the natural byproduct of this is the incredible amount of heat that is produced by these processors. In fact, the heat it produces is so high that if nothing is done to dissipate that heat it can actually permanently damage the processor.This is where heatsinks come in. Heatsinks are thermall conductive materials (usually metal but sometimes coupled with other heat dissipating devices) that help absorb this tremendous heat and then disperse it away from the heating component – in this case, the processor.

Some of the most common heatsinks are the stock heatsinks that come with the processors themselves. The most common metals used for these devices are aluminum, copper and steel – with copper being the most conductive and thus the best material for dissipating heat. But this effectivity also comes at a premium as it is the most expensive type of heatsink.

The fancy fins that is commonly seen in heatsinks are not there for decorative purposes. These fins increase the surface area through which the heat will dissipate. The larger the heatsink, the more heat it can hold and of course the more fins there are then dissipating that heat radiantly becomes faster too. Most heatsinks now feature active cooling in that there is a fan placed on the heatsink itself to help draw out the heat. There are also passive heatsinks that do not feature a fan or any other device to aid in heat dissipation.
