Received Refurb G5 - Fans Are Full On

[prof]

Update:
I tried resetting PMU, no change in full on fans.

So I downloaded Tempature Monitor and did some checking.

At idle:
Processor A averages 106. 2 F
Processor B averages 101.2 F

The only other reading that seemed concerning was the
Memory Controller Heatsink which averaged 129.2 F

Are these readings normal??

Any other ideas to tame these jet engine sounding fans??

TIA,
Prof


P.S.- Is it possible to do a Thermal Recalibration myself??
