Mac Pro with fan at full speed with normal temperature
I am helping a friend with a Mac Pro1,1 upgraded to 2,2
Firmware and SMC were upgraded, he change the CPU from two 2 cores to two 4 cores.
Now fan run at max. I installed Mac Fan Control and all temperature reported by the app seems ok.
I did reset the SMC by unplugging power 15 seconds, then replug and wait 10 seconds.
No luck
Reset PRAM even if I dont did that would help. (Waited 3 restart )
Any help would be greatly appreciated
