When putting a new computer together it is important to consider your air flow and what directions it needs. This is largely determined both by the case you select and your environment. In this article, we will explain the different forms of airflow, provide an idea of when one is better than the other, and show you how to determine which way the fan is blowing. It is important to note that this is a generalized guide and everyone's environment is different, some results may vary. Let's dive in.
Airflow
What is airflow and why is it so important? Airflow is categorized by what way your case fans are blowing and how it exhausts. Depending on how you orient your fans depends on the result you will get. Generally speaking, airflow is important to keep components cool, or at least part of the equation.
Fan Orientation
We make it as easy as possible to tell which way the fan is pushing or pulling the air. The main thing to look for is the TT logo that is located on the front of the fan. If you see the logo, then the air is being pushed out of the case. This orientation is known as an exhaust fan.
Note: The only time this rule does not apply is with the SWAFAN series fans, because they come with reversible blades to make the fan either exhaust or intake, depending on your needs.
If you see the support struts like the fan below, then you are pulling the air into the case. This orientation is known as intake. It is, generally speaking, used as a front fan to pull fresh air in. Note: The only time this rule does not apply is with the SWAFAN series fans, because they come with reversible blades to make the fan either exhaust or intake, depending on your needs.
