Ok so my pc case is the Corsair Carbide spec 02 with a windowed sidepanel. Up to 6 fans can be installed, two at the front ( 120/140 mm) and two at the top ( 120mm ) and one at the back ( 120mm ) and one at the bottom ( 120mm ). Which fans should blow wind in and which fans should blow wind out of the case?
 
I recommend having 2 fans at the front pulling cool air in, and a single fan at that rear pulling warm air out.

And obviously, a CPU Cooler fan, and if you have a discrete video card, fans on that as well.

Heat will rise simply due to the laws of physics. So normally you do not need nor want fans at the top of the case, nor on the sides of the case.

A natural flow from front to back, will keep the heat moving through and out of the case.
