Do these things run all the time? My speeds seem in line with everybody elses, Exhaust 599 CPU 499 Power 639 at the moment HD 800 (three drives) But don't these things ever shut down? My temps seem very low. I'd prefer a little more heat and a little more quiet. Might a fix bring these numbers down as these boxes run so cool? It is under my desk, and I definitely hear it all over the room, not that it is loud like when a MPB fires up fans or compared to most desktops, but still. I expected something a bit closer to the iMac in DBs when I am not pushing it. Is something wrong?
