Corsair H105 Exhaust or Intake?

Leirbag1310 · May 9, 2014

I'm getting a NZXT H440 and I was going to put the H105 in it but I can't figure out wether to use it as an exhaust or as an intake. Corsair recommends that you use it as an intake but then I'll have 3 120mm front intakes, 2 120mm top intakes and only one 140mm back exhaust. Will that create too much positive pressure?

Most builds use it as exhaust on the top - because its neater. Your top fans should exhaust (upwards)

+1 to i7Baby. Running it as an intake will gain you minimal to no difference in a lower temp vs. exhaust.

No such thing as too much positive pressure, the whole point of it is to have it so that air is able to push out of any opening in the case to help combat dust buildup. The more the merrier.

But the main reason it's recommended to have the H105 fans as intakes is so that you can push cooler outside air through the rad as opposed to the warm inside case air. It really doesn't make much of a difference though unless you're trying to run a crazy overclock on an i7 hex-core or that stupid hot FX 9590, in which case, the H105 would most likely be barely adequate anyways.

It depends on the case really. Example my HAF XB is very porous and it would be logical to mount it as intake in the front.

Set it as intake and the 140 in the rear as exhaust.

Setting it as exhaust will cause the hot air to bounce back into the case and recirculate due to the sound damping material. As intake it will pull the air in and the air will be pushed out by the 3 intake in the front and the 140 in the back.
