I currently have it as an exhaust but was wondering if it should be intake instead. The HD is right by the fan and I was thinking flipping the fan to intake would blow more air over the HD (which gets rather hot, Seagate 7200.10 750gb)? The only other fans that fit in this case are the CPU fan and the PSU fan as far as I know
I know this might sound like a dumb question, but as I said this is my first build and I don't know that much yet!
I'd choose to mount as intake. I'd also put a dust filter on its intake to reduce dust buildup inside the case. If it was not part of teh case, mount one on the outside where it's easy to get at for periodic cleaning.
