Case fans configuration

[sekb]

Hello dear people. Yesterday I installed new fans, Be Quiet Pure Wings 2, in my case which is Zalman R. Now I have 2 intake fans in front, 2 exhaust fans in top and the last one is in the back, but I do not know if it should be exhaust or intake. Thank you for your information.

The back fan is exhaust in 95% of the cases and ur case scenario is 1 among them.
That will be true especially if u have an air cooler positioned to mirror the air flow so that the exhaust of the air cooler will exit through the back of the case while talking fresh air from the front intake fans.

errm it depends on if you want positive pressure in your computer or negative
positive air pressure will reduce dust but decrease the cooling effectiveness.
negative air pressure will get you more dust but run cooler basically meaning more maintenance
to get positive make your fan a intake but to get negative make it a out take fan
