I just got my new custom computer in the new CM 690 case. Happen to have a couple of extra 120mm fans lying around that I wouldn't mind throwing in for some extra noise and light. (I enjoy my computer sounding like a jet engine) Problem is I'm not a tech savvy person. Anyone have any suggestions as to where to mount these and what orientation (intake/exhaust) they should be in? If you don't already know it comes with 3 stock fans; 1 bottom front, one rear top, and one on the side panel. That leaves 3 open locations, 1 in the side panel next to the aforementioned stock fan, and 2 in the top front. Also the power supply is mounted on the bottom, and I assume that should be taken into account.
