Which HAF X Fan Setup is Better?

post #1 of 9
Thread Starter 
Since I overclocked my CPU, the air coming out of my case is much warmer. My CPU only gets up to 45, but my mobo gets up to 55. My video cards get to 70 and 55 respectively, with the top one getting hotter because it only has two inches clearance above the other.

These temperatures aren't bad, but I was wondering if I could get better airflow by removing the rear 140mm fan, getting the CM Hyper 212+ and pointing it up instead of my Sunbeam pointing to the back, because from what I've seen you can get a 4 or so degree difference by pointing your CPU fan up instead of to the back. I would also install the second top fan, so ALL air would go from the bottom and side to the top.

See the diagram and tell me which is better, setup 1 (my current), or setup 2 (my proposed one).

! would say 2 because you have the dual fans on the cpu HS with the 2 120mm fans at the top sucking air out of the case thus pulling more air into the cooler and cooling it down.

Make sure you get a 120mm fan for the back though pulling air out too because you need to draw the heat from the gpu's out of the case and away from the cpu smile.gif

So you're saying to leave the rear 140mm fan on as well?

The way I would do it is like this.

Have the fan layout of pic 1 but the cpu turned the same way as layout as 2 dual fans with them pushing the air up.

Sketch #1, with two top fans pushing cold air down. It feeds air to the heatsink and keeps hot exhaust from the gpu's down so it won't be ingested by the heatsink.

Exactly this, have your front fans intake, top 2 fans intake, and side intake while leaving the back as exhaust. The air from the top will keep the videocard air from going all over the top of the case and will get pushed out the back grill mesh behind them while the heatsink goes directly into the back exhaust. This will also give you great positive pressure and with a couple filters you'll never have to clean a hafx.

I'm so going to do this. I need to pick up another 120mm fan, any suggestions?

TY-140mm, can be mounted on 120mm
or Prolimatech Red Vortex 140mm

almost same ~19dba and pushing a nice amount of air

also add another 140mm in the 5.25 bay area.
