Q: Power Mac G5 Dual Core gets hot and fans run slow
Hello
I have a Power Mac G5 (Late 2005) Dual Core that has fan problems. The temperatures get high and the fans barely spin up. The CPU fans sit at 499 and 515 rpm and when playing Minecraft they go to about 600 rpm and the CPU gets up to 151F. I have ran Apple Hardware Test and it still doesn't work. It is running Mac OS 10.5 and has 6 GB of RAM and has a 500GB hard drive. I have:
- Reset PRAM
- Re-installed Mac OS X
- Replaced Hard Drive
- Cleaned dust
- Ran AHT
- And reset the SMU
- Tried editing AppleFan.kext
iStat pro says the fans spin about:
CPU A intake: 499 rpm
CPU A exhaust: 515 rpm
CPU B intake: 499 rpm
CPU B exhaust: 515 rpm
Backside: 1000 rpm
Slots: 1500 rpm
drive bay: 1000 rpm
Is this normal? Do they always spin slow or is there any other things I can do or software to download?
PowerMac, Mac OS X (10.5)
