Question Is intake and exhaust fan different?

[Tsumirin]

Hello, I cannot understand the difference between intake and exhaust case fans while seeing the products on market. How will I identify the fan as which one is intake or exhaust fan for CPU case?

There might not be a difference, the only change per say is the direction air is blowing so you could use same fan for both purposes. I have. Just turning the direction that the fan faces, changes it from intake to exhaust. Most fans can be intake or exhausts. Its your choice.

Main difference between fans is are they static pressure which are good for radiators, or just air flow. - https://pcgamehaven.com/static-pressure-vs-airflow-fans/
