The exhaust fan has a higher airflow rate specification compared to the intake fan.The exhaust fan spins faster and is the same size compared with the intake fan.More exhaust fans of the same size or larger than intake fans.And, of course, we are referring to all the fans inside the case as a collective. The exhaust fan(s) have a higher airflow rate compared to that of the intake fan(s). Negative air pressure means that more air is going out than in. Intake fan: The blowing side is facing the inside of the case and draws air from outside the case and blows it inside.It draws air from inside the case and blows it outside. Exhaust fan: This is the fan that has its blowing side mounted to the wall of the case.To help you understand my explanation better, here are the two types of fans I will be referring to: We will start out by taking a look at the three ways to configure cooling. The main three types of airflow configurations Here’s a link to my review of the top CPU cooler on the market. A complete understanding so you can configure cooling like a pro. The true challenge is keeping it cool, quiet, and clean as time passes. I’ll just mention though, that it’s easy enough to create decent airflow through the inside of a computer case and get the system temperature down to acceptable levels.

So I’m going to share all of them and point out which one I recommend based on my experience after building hundreds of computers from scratch. There are various ways that you can configure the fans to give you different results. This way, you will be able to set up the cooling fans the best way for any situation. In order to optimize the airflow in your PC, it’s best to gain an understanding of how cooling works inside a computer case.
