Recently aquired a very nice PM G5 2.5ghz Quad, the machine works perfectly except that the fans speed up to over 2000rpm very quickly (quite loud noise) from it's "idle" 900-1000rpm when I put on some very slight load on the cpu's...and the temp difference between the two CPU's is around 20-25C which isa kind of worrying
I've vacumed the heatsinks from the front side by removing the CPU intake fan assembly, reset the PMU, ran the apple diag DVD which reported no errors and did the thermal calibration but still the temps differ between the CPU's and the fans go quite loud without me pushing the machine.
iStat reports both liquid cooling pumps operating at the same speed.
Any idea's?
