What kind of case do you have? I ask cuz if the psu fan is very close to the hs/f(and that 80mm at the back) it(the hs/f) might not be getting enough air ...easiest way to check if the hs/f isn't getting enough air is compare rpm's with the side of the case off and on
lower rpm's with case side on mean there might be a vacume around you hs/f
Well, the PSU fan sits to the right side of the HSF, with about 1/4 the diameter overlapping the top-right-rear corner of the HSF, all in relation to the motherboard. So, I don't think there is a problem with it. The HSH has about 5-6" of headroom betweent it and the side of the case. There is no part of the HSF that is under the PSU, in relation to the mobo.
What I meant earlier was that in the more universal term, as in the ceiling is above my head, the PSU sits above the HSF. But really it sits above the side of the HSF.
after a year of trying different setups the best method I've found is:
-sealing up all the holes(not every pin hole though)
-have just a little more air comeing into the case than going out(at a db level you can tolerate)
-bundle up cables that might reduce airflow
Yeah, I probalbly should bundle a few cables. I just don't know a good way to do that without kinking the IDE cables. The last time I had tight IDE cables I ended up damaging one of them, which caused havvoc in Win98. As for power cables, I'm not sure theres much I can do. One big problem I do have is that Abit put my PSU socket on the left side of the mobo, if you look at it from the front, but my PSU is on the right side. So, I kind of wrapped them around the side of the HS, trying to keep it over the solid parts and away from the fins.
As for having more air than coming in, this was a REALLY crappy case that I bought in haste on a low budget when my original PSU died. The store that I bought it from was selling the PSUs for more than the new cases with PSUs, so I took a case. I wasn't all that smart about using quality hardware in those days.
Anyway, this thing came without any front vents. There is a grill in the interior that was about an inch from solid plastic, if you can imagine that. I found that it was quite easy to drill some holes in the plastic where there were already some dimples. It's not something that looks handcrafted, it looks like this thing came with holes, but really it came with dimples.
BTW, that's the one fan that I forgot to mention, I have a fan behind that grill blowing air in. It's my only intake fan. Unfortunatley, those holes aren't very big, thus I get little air coming from them. I can tell this because a sheet of printer paper get's moved very little when held close to it. However, the fan is moving the air around in the case pretty good. It primarily sucks air from behind the front panel, but there are all sorts of grill holes on the same metal plate that it's mounted to.
to keep your hd temps down you could attach it to the bottom of your case with a 5¼ drivebay adapter and some screws
I'm not sure how I would accomplish that. The entire bottom plate is solid metal, with the exeption of a 2" Dia. air grill.
I have a 92mm 56cfm intake and 80mm 37cfm psu exhaust in a tower case, system temps stay with in 1 or 2ºC of ambient temp
I'd like to know where your system thermomter is. I'd also like to know just what kind of a CPU your running, and whether or not it's idle, and if it's oc'ed or not.
My CPU is an AMD for starters, which generally run hotter than Intels, well the lower ones to at least. It's a Barton 2500+ oc'ed to 3200, and I'm getting these temps at 100% CPU usage (folding) after a couple hours. Add to that the fact that my last Abit system thermometer was right next to the CPU socket, and I don't doubt that this one is as well.
