Side Fan for HAF 912

post #1 of 6
Thread Starter 
I added a Megaflow 200mm for the front of my HAF 912 and had a 80cfm/40db fan for the exhaust.

I'm now left with the 2 stock 120mm fans. I have a shelf right above my case, so I don't really want to exhaust heat out the top.

My question becomes - would putting one of the 120mm fans on the side panel provide that much more cooling? Because of the placement of the fan, it seems it would only help cool the GPU(s) - which don't really run that hot in the first place (EVGA Stock GTX 560 oc'd to 854Mhz). If you do recommend it - do I use it as exhaust or intake?

Thanks.

The two 120mm fans I have on the side seem to only cool my gpus like 2 or 3 degrees when I run them, but I do it for the hell of it since the option is there. You would need to do them as an intake. For some crazy reason, when I set them up as an exhaust my gpu temps went higher than they would have without the fans there.

You can have 2x 120s as intake on top to give you positive pressure.

Hmmm - have you done that? Does it actually help?

Also - is it a problem im only running a single 120mm as exhaust? Shouldn't air flow be somewhat balanced?

The stock CM fans aren't too great at moving air at all... I wouldn't be surprised if there wasn't any change in the gpu temps after installing one, cause there sure wasn't any change in mine.

Air flow can be whatever the hell you want. If a setup doesnt work for you then you can change it. I'm using mine as intake as it results in 4-5c lower temps and positive pressure prevents dust in the case.
