Pc Case Top Fan Exhaust Or Intake

Logically the fan would be set to exhaust because hot air rises but what would be the effect of using it as an intake instead.

Pc case top fan exhaust or intake. So i m getting a top 200mm case fan. But i mod the case and changed all the fans. 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. Now my cpu heatsink and such is close to the the top so i figured if through a fan on top that would help cool too as an intake as it s close.

The intake exhaust direction should go front to back and bottom to top. Back middle front etc. 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. Fan support up to 3 120 2 140 mm intake fans 2 140 mm included up to 2 120 140 mm top fans up to 1 120 140 mm exhaust fan 140 mm included front intake panel type part mesh if you dislike the traditional tower shape of pc cases then opting for cube cases is a genuine option.

Intake fans brings fresh air into the pc while exhaust fans kick stagnant air out. This is the role of intake and exhaust fans. Running prime95 for 2 hours and cpu never went past 70c. The key therefore is to add fans that either get rid of this ambient heat or bring in fresh cooler air to be used.

Side mounted fans can be intake or exhaust depending on the setup. I e been reading. So there is two intake 120mm 60 70cfm on the front and 133cfm exhaust fan on the back and the 230mm exhaust fan on top my cpu cooler is the xigmatek dark knight my system stays nice and cool even in gaming and video encoding. Currently everything is set to default 200mm intake front 140mm exhaust rear.

Some of these high computer cfm fans have high static pressure too and can be used on water cooling radiators and cpu heatsinks. As for their differences it s very simple. I have a nzxt h500 case it has 1exhaust on the back and 1 on the top aswell and i have a nzxt kraken x62 for cpu liquid cooling and the radiator is mounted at the front with 2 intake fans. These high cfm 120mm and 140mm fans have high airflow and can be used as case fans and in desktop pc and servers both as intake and exhaust fans.

I agree with everyone here but in my situation top fans are intakes and i have 1 140mm exhaust. Best high airflow fans for pc case. Manage your cables and other obstructions.
