jrrjrr Posted January 8, 2007 Share Posted January 8, 2007 I have the same issue and I just started looking into it. It was fine before my most recent upgrade. I have a list of loaded kexts from before and after the upgrade and I note some changes which I am looking at one at a time. I hope to hit the one that changed the fan behavior at some point this week.

frizbot Posted January 9, 2007 Share Posted January 9, 2007 ACPICPUThrottle.kext no longer works on 10.4.8. It's what uses speedstep to decrease the CPU clock to save battery. Because of the high CPU clock, much more heat is generated, needing the fan to cool the laptop. That heat makes the fan stay on. Many laptop users are waiting on a fix for this. It is discussed here- http://forum.insanelymac.com/index.php?sho...4915&st=360 You could downgrade to 10.4.7 and install that kext, but that is a downgrade and other hardware may have issues with it.

jrrjrr Posted January 22, 2007 Share Posted January 22, 2007 I was able to get my fan speeds back to the way they were before the 10.4.8 upgrade by grabbing the file "AppleIntelCPUPowermanagement.kext" from the 10.4.8 Delta Update (from Apple). I used Pacifist to extract it to my desktop and then moved it to /System/Library/Extensions/ and repairing permissions and rebooted. I don't notice any degradation in performance of the system, just much less time spent with the fan running. It still will come on under heavy CPU use, like it should.

frizbot Posted January 22, 2007 Share Posted January 22, 2007 Please post this kext! I'm not sure which update to download. Link to comment https://www.insanelymac.com/forum/topic/37845-notebook-fan/#findComment-281499 Share on other sites More sharing options...
jrrjrr Posted January 22, 2007 Share Posted January 22, 2007 I hope this is ok to post here. It is freely available to anyone who downloads the full update package from Apple's site.

frizbot Posted January 22, 2007 Share Posted January 22, 2007 This may be subjective. I installed the kext, and sysctl -a still gives my max processor frequency as also the minimum.

jrrjrr Posted January 22, 2007 Share Posted January 22, 2007 Yes, I also still get max/min the same with this kext loaded. What it is doing for me is a least seeming to change the temperature thresholds for the fan to go on and off to more appropriate levels.
