Build a computer: More Cooling

General information

 We talked about the CPU Cooling a bit already. The CPU isn't the only PC components that needs cooling  in a computer.

The GPU, too, needs cooling, but every discrete GPU that you can buy already comes with an attached heatsink and cooler on top of it, so we don't have to worry about extra cooling for the GPU. Now, because the PC case is usually closed shut, and the PC components inside the case need coolish air to not overheat, there should be a way to blow colder air from outside of the PC's case into the Case.

This is done by attached Case fans to the inside of the case These then pull in cool air at the front of your PC and blow the hot air out the back of the PC, creating so-called airflow throughout the case. This way, the inside of the PC-Case and all of your PC Components ideally stay nice and cool and performance isn’t reduced through things such as thermal throttling.

Here is a size comparison:

Usually not, as most cases are shipped with extra fans that will do just fine for this purpose. If you are thinking about building an extraordinarily quit/silent PC, though, you might want to get higher-quality case fans than what is shipped by default with a standard case.
