My Cooler Master HAF-932 has a large fan on the side. However, when I remove the side, I have to unplug that fan. Temps start rising even with the side completely off the thing. Years ago I bought a little 9 or 10 inch fan that plugs into the wall. Usually I use it to cool my upright freezer when I'm freezing fresh packed meat and the freezer has a load on it for hours at a time. I sometimes buy 40 or 50 lbs of meat to freeze. Anyway, when needed I use that fan to blow in place of the side fan. It blows a larger volume of air, even on low, but it keeps the temps down to what they are with the side fan in place. Sometimes the temp rises 10 or 15F without that fan, mostly things like the video card and such. CPU stays pretty close to the same.. Amazing how that slow spinning side fan does that. ;-) I usually place mine towards the front blowing towards the back. That is sort of the natural flow for this case. However, in your case, you want air blowing on the drive itself so I'd set it to blow across the drive either at a upward or downward angle. I'm not sure if the heat is even or more on top or bottom. Most likely, either will help. Yea, I'm a country guy who has learned to do things with little to nothing. I'm good at using something for something other than what it was intended for. o_O Glad to help. Sometimes the simple things even escape my notice. Dale :-) :-)
