The fan is indeed audible. It is not that noisy as a stand alone computer (there are at least two noisy fans afterall) but I could easly hear mine from 10 feet away.
Fortunately there are at least 2 ways of solving this problem.
One is replacing the stock noisy fan with a high quality one. I got a Papst fan from a computer outlet, that was DEAD quiet. I set me back 20$ (the one the sits in PP costs probably <1$).
The other is disconnecting the fan altogether. It can be safely done on P300 (early ones came with no fan at all) provided do not draw more than 100W from it. I got that info form PS Audio, FYI.
