I really dont think the cooling/noise of a power supply should be the most important things you look at in buying a power supply, no offence.
Stick with PCP&C/OCZ, Corsair, Enermax, Silverstone, Mushkin, and Xigmatek for power supplies. Even the new line of Antecs are very nice, the Earthwatts and Neopower(i think?). They are tested up to 50c, so are the Mushkins.
Zalman hasnt made a new CPU cooler in ages and their current lineup dosent do well with quads and newer duals as others do, espically for the price, and there GPU coolers are vastly overrated. That same quality/business strategy caries over to there power supplies, Zalman was a good name 2 years ago before the likes of Xigmatek and the AC7. But..."what have you done for me lately?"
