Usually this PowerMac G5 is very quiet (much nicer to sit next to than its Mirrored-Drive-Doors G4 predecessor).
But in the last couple of days, it has been doing a funny thing: when waking from sleep, all the fans come on and stay on. But a restart sorts it out, all back to quiet again.
Yesterday it persisted once through a restart. Today I can't get them quiet at all. They're going mental no matter what I do.
I downloaded a program which prints out information from the temperature sensors, but none of that seems out of the ordinary.
There's supposed to be some daemon running which tells the fans how slowly to go (if it crashes, they ramp up to full speed). Does anyone know what it is called, so I can check that it is running?
Is it otherwise possible to work out why the PowerMac thinks the fans need to be going at full whack?
Long shot: make sure the door is closed properly and and that the perspex cover is seated. There's a switch which makes the fans go on full power when you remove the cover so it's just possible that it's intermittently registering that the cover is off.
