r00t wrote I'd put the three 200mm fans as intakes. One at the front, one at the site, and the top one on the front mount on top. This will create a lot of positive pressure in the case that will be pushed out the back. You can also remove unused PCI slot covers to increase airflow by the card. The 140mm fan at the rear won't be of any use, really.

I don't really believe in using fans for exhaust. You don't necessarily need fans to push air out the back because the pressure does that for you.

The newer model of the 630 (the one I have) has zero side mounting options. It's a simple window.

So there's only two of them to play with

I was under the impression that having three exhaust fans situated so closely together would work well
