Hello! Anyone else here with a very warm power supply in the 20" Alum iMac?
Mine is real hot :/
(The screenshot is taken 2sec after I turned on the higher fan RPM's.. The high temperatures occurs in the default setting.)

Run the fan speeds at 1500/2500/2000 still quiet, power supply runs around 42C .

EDIT.

Double checking your image, I notice your fans are screaming right now, wonder why it's so hot running that fast. My stock fans are 700/1200/1200 PSU gets to 79-80C at that, but running 1500/2500/2000 gets at most 50C.

He said he turned them on high.

P.S What app is that? iStat?
 
What I can suggest, take a 15lb BFH to the iMac and get yourself a Dell or Gateway, they don't have problems, obviously.
