Temperatures
Throughout testing, the temperature of the heatsinks remains very low. The inside of the power supply tends to hover around 5°C above the ambient temperature. This means that the heatsinks are not getting hot at all and in addition they can easily dissipate the heat to the air.
Fan Speed
However, the low heatsink temperature results in a large part from the high fan RPMs. If Zippy wants to create a better power supply for the mainstream they definitely need to focus a bit more on fan selection and speed. Since the heatsinks and thus the inside of the power supply are not getting too hot, it should be possible to run the fan at much lower speeds for this PSU. The maximum fan speed tops out at over 2500 RPM, and at room temperatures it's not much lower, which certainly appears to be more than is required for this environment.
Acoustics
The noise levels are not particularly bothersome, but they are nevertheless clearly noticeable. If you mount the power supply in a decent midrange to high-end system you will probably not have any problem with the noise, since graphics card and CPU cooler will contribute a fair amount to noise levels as well. In comparison with previously reviewed products from Zippy and PCP&C, we can say it is definitely quieter. Does this power supply provide a feeling of serenity? We might not go that far, but at least it didn't annoy us.

When will you test some Seasonic PSUs?USAF1 - Monday, September 3, 2007 - link
Yeah, I'd love to see the Seasonic S12 Energy+ series tested. Seasonic claims a peak efficiency of 88%.Christoph Katzer - Monday, September 3, 2007 - link
Will come this week...USAF1 - Monday, September 3, 2007 - link
Sweet...InternetGeek - Monday, September 3, 2007 - link
89% efficiency means the PSU doesn't dissipate almost any power at all as heat or whatsoever. This is a legent waiting to happen in terms of PSU ;)Christoph Katzer - Monday, September 3, 2007 - link
Quite possible. First it was with 230VAC where we have seen already 86% and these 2.7% more is definitly possible. I have seen already 3 years ago efficiency of 89% from a handmade PSU sample at Topower's factory in China.
