Its very strange because my dualPowerMac fans are working like crazy at some certain point after a task. Then the system crashes. What might be causing this noise fan behaviour? The only solution to make it stop is by clicking the power on/off button., but as you can understand thats definately not a way to carry on!
Got a tip for us?

I've had this a few times on both G5's and MacPro's
It was simply "dust" inside the case !
A good "take apart" and careful cleanout sorted the problem.
On my last macpro V 1.1 - Quad 2.66 it was "screaming" for a while and this
was the graphics card being covered in a dust layer ! ( it's small fan went crazy)
Get it off your boards / fans and memory
I have to do this every 2 months to keep mine clean and quiet.

also let me say that the computer first freezes and then the fans start to go crazy! what can i check for? i have already repared permissions etc!
Give it a good blow.
.. and then do it again
When the fans go crazy after a crash, does a red light turn on in the inside? What kind of G5 do you have?

As it seems, the problem is actually he crash and not the fans spinning fast, which seem rather to be a secondary effect (fail-safe)...
Is the problem reproducible?
Did you do something CPU-intensive right before that?
Did you add more RAM recently?
Did you try to boot from another volume / OS?
Did you check the system log in the console? (might give some info about the crash)
That's all I can suggest at the moment...

This doesn't sound like a fan issue at all. This sounds like a kernel panic. When the machine panics, the fans will go up to full blast because the fan control extensions have dropped off.
Something is wrong with your OS, or some other hardware.
(Edit: saw your latest post. Don't the G5's need to be fan tuned after a CPU is replaced?)

Fan tuned? very interesting, that might be something to search for! How can the G5 be fan tuned?
End user can't do it. But the Mac tech who replaced the processor is supposed to. I never owned a G5, but I recall something about a cd needing to be run after a processor is replaced.
it seems i have to do it on my own cause i cannot spend any more money for this mac, if anyone can help me on this it be cool!
You've got to get the Apple Service Disk.

Was your tech Apple authorized? He should have done it for you.
well the company i work for (G5 belongs to the company) thought that the cost was big to spend on fixing an old G5, and also i must say that the companies ITdept the only care about pcs because they are cheaper, so now i have no alternative other than trying to fix it on my own!
