The air cooling method involves using multiple fans to reduce the temperature of all internal mechanical components. Currently, components such as graphic cards and processing units come with great stock fans, so you don’t really have to worry about overheating if you don’t employ all of your computer’s resources.
However, if you are looking to get the maximum out of your desktop PC, you need to consider upgrading all internal fans, as stock ones guarantee only minimal performance.
Installing air cooling system on your desktop PC is much easier and a lot cheaper when compared with liquid cooling. Even, if you have to upgrade all of your PC’s fans, you will spend far less than for liquid cooling system.
The main disadvantages of the air cooling method are that fans are pretty loud, less efficient than liquid cooling systems and also the heat sinks for particular fans get pretty big.
