a 55cfm 23dba 120mm and a 30cfm 22dba 80mm fan is much quieter than a 46dba 80mm fan ;)

exactly my thoughts.... the stock 80mm is VERY loud

no fan is much quieter than any fan ;)

but the sound my $200 psu makes when you short out the heatsinks is byfar the loudest =)

well the copper part was cut to make little fins... also the other 2 main aluminum heatsinks also have this same copper finned heatsink on the opposite sides of their chips....



also... there is a series of air holes cut out of the casing next to this little heatsink

maybe its a dual purpose heatsink/emi shield



wouldnt it be cool to have a pcp&c engineer in here? he could tell us exactly what is and what isnt safe to be doing to it.... and exactly why some heatsinks are live and some arent.

If you happen to know an electrical engineer who's got access to a lab or at least an oscillo, bring the PSU to him he may tell you whats up :p PSU's are very easy to reverse engineer, they're all made the same so differences are quickly noticeable.

I doubt it, probably just tell you removing the cover would void the warranty, and be horrified at the idea of water-cooling one :p

iv been wanting to wc my psu, its only got 1 line of mosfets, and i havent got around to design my wb, but its gonna look similar to the heatsink, the heatsink is a big T, but im only worried about the conductivity, i was thinkinga bout getting non conductive aluminum...
