Since we still have a couple of PowerMac G5 and a few recent Mac Pro test units in the lab, I fired them up with a cooling system test app to see how different the noise at nominal and full blast cooling. These machine are about half populated with hardware and such.
My answer: not much. Very precise, I know. ;-) It takes longer for the full blast cooling to kick in on the Mac Pro so you'd run into the noise less of the time. But the difference is not by my ears a huge one.
