Takahashi Posted September 1, 2014 Share Posted September 1, 2014 Hello! My Lenovo Hackintosh has its fan almost always running, overheating sometimes. I have to manually fan it to keep it from overheating, though that doesn't help much. I turn on the A/C, fan the computer, and it still overheats. This also happens when trying to install the Mavericks 1.9.1 update. It tells me "3 minutes remaining" under a progress bar and "Software Update". Then the fan accelerates and the computer shuts down immediately This is not the situation in Linux/Windows/Unix. What can I do to get the fan to run normally/keep this thing from overheating? Thanks! Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted September 2, 2014 Administrators Share Posted September 2, 2014 are you running null cpu? it looks like you need to tune your power manegment. Link to comment Share on other sites More sharing options...
Takahashi Posted September 2, 2014 Author Share Posted September 2, 2014 I don't have the Null CPU Power Management .kext installed, should I use it? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted September 2, 2014 Administrators Share Posted September 2, 2014 what are the specs for that machine? all i keep finding is an AMD core version. if so thats probably the issue. apple power management is intended for Intel cpu. you can try adding nullcpu to see if the temps change.

Takahashi Posted February 22, 2015 Author Share Posted February 22, 2015 Oh my word, I apologize for my, what is it, almost six-month later response... I swayed from OS X for a while, but now I am back. Concerning the overheating, it is no longer an issue although I have AppleIntelCPUPowerManagement.kext installed. I opened a sealed vent on the bottom of my laptop's case, which is directly below the fan. I think that is what solved the issue. Link to comment Share on other sites More sharing options...

Takahashi Posted February 23, 2015 Author Share Posted February 23, 2015 Quite true! I may test the Null CPU Power Management kernel extension, and see how my system fares. I will post the result. Result - The fan runs beautifully. Link to comment Share on other sites More sharing options...
