Cpu Fan Intake Or Exhaust

Manage your cables and other obstructions.

Bathroom fan adapter. As for their differences its very simple. You will also be able to identify the exhaust side as you will see power wires entering the fan motor. Of course theres the cpu and gpu coolers as well as the psu playing into it.

Top fans pull exhaust. A single intake fan with no exhaust fan is positive pressure. This is the role of intake and exhaust fans.

The rear or exhaust side the side that the air comes out of of our fans will always be the side that houses the fan motor. So to answer your question exhaust for the cpu fan as anything else would be counter productive. Intake fans brings fresh air into the pc while exhaust fans kick stagnant air out.

The key therefore is to add fans that either get rid of this ambient heat or bring in fresh cooler air to be used. Make sure you filter the intakes too and avoid putting intakes at the top of a case because heat rises dust falls and top intakes are not usually filtered. You want as close to a laminar flow as you can get which just means as smooth and unobstructed as possible.

Your front intakes will draw cool air in while the rear exhaust fans will expell all air creating a cycle. Different flow affects dust build up just as much as the case and house itself. Intakes blow more than exhausts.

The heatsink fan exhausts the hot air drawn off of the heatsink into the case. Bottom fans push intake. The intake exhaust direction should go front to back and bottom to top.

Side mounted fans can be intake or exhaust depending on the setup. You can use an aio as intake or exhaust but having it as an intake at the front would give lower cpu temps.
