I don't think that's the fault of the power supply - it's designed to cool itself, not necessarily the entire box. Running a hot system like yours, you probably need a least one case fan. Try two low noise 120mm fans with speed controllers on them - one at the front of the case, one at the back near the CPU. Personally, I've found the Zalmann 400W to be really well made and quiet. The weight alone gives you an idea of the quality - which of course has to be paid for. Cheers Daniel
