remeron Posted September 22, 2009 Share Posted September 22, 2009 I managed to installed a vanilla snow leopard on my system: Core2Duo E4500 at stock speed with stock HSF Gigabyte P35-DS3 XFX 8500GT 4x1gb DDR RAM The problem I have is that my CPU temp is running around 65C! I read that it has something to do with the nullcpupowermanagement.kext file which apparently has to be loaded for SL to run properly. Is there a workaround for this? Or am I looking at having to buy a proper HSF? Thanks in advance for any input.
