the fans blow from the back of the drives towards the front(the part where the wires are plugged) [obviously] anyway its according to case manufacturers specification. the space where the hdds are is a little bit isolated from the rest, its quite smart
@Bigspy:
I said according to HDD manufacturers...but hey, what do the people who MAKE the shit know about it?
I've been building servers and workstations probably while you were still in diapers, and I severly doubt your friends have a drive 10 years old and still runs that hasn't been off for 9 of those and at those temps.
You say you have a 310w PSU? Well, you must have a real slow prescott, because at full load, a 3.6GHz prescott draws OVER 310w...hmm...maybe your computer is special.
Most HDD's will survive high temps, because I guarantee there is airflow on them of some sort, and as long as that is the case, they're temps are alot lower than standing air.
From my experience (oh boy, it's quite a bit too!) 535w is not enough. Given most newer CPU's can draw more than 200w, and GPU's can draw near 100w or more (depending on SLI or configuration/overclocking).
@Poster: As long as you got a fan on it, you're good. You can DL S.M.A.R.T. and see if your drives are dying.
