Been using this for 2 years now with ZERO problems what so ever.
I admit it is much larger than I expected but that's not a problem!
Currently I'm only running two fans on it, my chain consisting of a Radeon X800Pro card, an Athlon 64 3500+, and my Nvida4 chipset. Even after going through all thatm and only using two fans, I'm getting 35c on the processor under typical use. In heavy load I've never seen anything higher than 42c. The air in the case is warmer than anything else.
