Needs recommendations about case fans setup

[hdouss]

Hi !
I am about to install 3 fans for my case (MS-TECH CA-0330), one on the rear side (air out) and two on the front side (1 air out+1 air in). All the fans are placed rather on the top half of the case. Is it a good choice? Is there some better recommendations? For the front side fans, is it better to make the air out fan on top and air in on bottom or the other way?
Thanks in advance.

Never have two fans on the same side opposing each other. All fans on one side need to be in or out. This causes turbulence and really just the fans cycling air back and forth with each other, which doesn't do anything for your case. Do all front fans as intake, and the back fan as output. Should be a good setup.

Generally, you want the air to move from the lower front of the case to the upper rear. The logic behind this is that you want the CPU heat to exit the case as quickly as possible, and you want the coldest air to pass over your hard drives or ssds. Hard drives in particular are very sensitive to changes in temperature, and historically achieve twice the lifetime for every 10 degrees C decrease in temp. I don't know if that rule holds for SSDs, though.

Regardless, you don't want to blow the heat from the CPU and GPU across the rest of your system.

As far as having an intake AND exhaust on the same side, nothing good will come of this. Ever. The resulting flow of air simply enters the intake, leaves the exhaust, reenters the intake, and simply repeats the loop. Keep your exhaust as far away from your intake as possible. In your case, you want two intakes on the front, and one exhaust on the back.
