Pc Case Side Fan Intake Or Exhaust

The side fan forces air directly onto the hottest component the video card which is then swept up by the airstream produced by the front fan and escorted out of the rear exhaust fan.

Pc case side fan intake or exhaust. You will also be able to identify the exhaust side as you will see power wires entering the fan motor. Manage your cables and other obstructions. Pets bugs and. You d still want an intake fan so you re getting a draft of fresh air through the pc but leaving the case side open allows the heatsinks to expel the heat outside the system by themselves.

Different flow affects dust build up just as much as the case and house itself. The graph below shows that the side panel fan still continues to have a massive positive effect on cooling even with three fans installed the three setups that performed the best in this test all included a side panel fan. Side mounted fans can be intake or exhaust depending on the setup. Since i have a liquid cooler they only put in one 120mm top fan because that is all that would fit.

I ran with 2 exhaust fans on top but because my push pull radiator setup is on the front as an intake due to better temps my top fans are intake for the motherboard and have a fan profile to slow them s own slightly. The intake exhaust direction should go front to back and bottom to top. Of course there s the cpu and gpu coolers as well as the psu playing into it. I would think that the number of intake fans should be more than the number of exhaust fans like you said.

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. The top fan is an exhaust and bottom fan is an intake. Generally it s best to have as few obstacles as possible between the intake fans on the front of the case and the exhaust fans on the rear and top of the case. A single intake fan with no exhaust fan is positive pressure.

I still have good positive pressure in my case and temps are 2 to 4 degrees better than when i ran the top as exhausts. The side with the guard motor support lastly the fan airflow can be identified by the arrow markings on the fan. The power supply is probably drawing air from an aperture in the base of the case and so is isolated and not really affecting the case s airflow the arrow for that one should probably be a right angle feeding in from the bottom and turning left to point out of the back of the psu. However at the same time keeping the side panel open exposes the pc to new problems such as an increase in dust settling on hardware.
