dino7777 Posted February 15, 2010 Share Posted February 15, 2010 Hi, after installing istat i reconized that my SL installation runs about 20 degree C higher CPU temp than leopard. I have Speedstep enabled Checked that speedstep is in deed workin over CPU-I app (needs installed cpui.kext) Somehow I dont get it how SL makes cpu temps so much higher even with speedstep working? At full throttle my cpu gets up to 80 degrees Any ideas, what do Imiss Regards Link to comment https://www.insanelymac.com/forum/topic/210825-sl-is-hot-ie-cpu-temp-much-higher-than-leopard/ Share on other sites More sharing options...
mR.GeeK Posted February 15, 2010 Share Posted February 15, 2010 Same Problem here! Link to comment https://www.insanelymac.com/forum/topic/210825-sl-is-hot-ie-cpu-temp-much-higher-than-leopard/#findComment-1410486 Share on other sites More sharing options...
dino7777 Posted February 15, 2010 Author Share Posted February 15, 2010 I wonder if maybe just the shown CPU temp values are false ?!?!? maybe the apps get wrong senor values I switched my E6400 Intel Core2Duo 2,23GHz back to its default speed, i.e. 2,3GHz. On the CPU there is a hugh Skythe Ninja cooler attached, that is a 12cmx12cm metal block with a 12cm fan. Really on the best fans around. The fan has a constant speed of about 1000RPM. Activity monitor shows a constant CPU usage of up to max 5% and still the "measured" CPU is CPU A 56 ºC CPU B 51 ºC Strange how and why should the CPU temp be as high as that CPU usage low Voltage settings correct (that is what CPU-I shows Same CPU speed, voltage, etc. gives 10 degrees lower values in 10.5, Windows and Linux For me it is a mistery The only conclusion that makes sense is that somehow the real CPU temp and the displayed CPU temps differ Link to comment https://www.insanelymac.com/forum/topic/210825-sl-is-hot-ie-cpu-temp-much-higher-than-leopard/#findComment-1410555 Share on other sites More sharing options...
mR.GeeK Posted February 18, 2010 Share Posted February 18, 2010 Nop, if you check with the Bios, You'll see that they are not false! It is really strange.... only way to find out if it's a malfunction, is by getting a real Mac pro case, and test it!!!!

omnidecay Posted February 18, 2010 Share Posted February 18, 2010 Idk what your setups are but for me I had to install the voodoopowermini.kext. From my research there are 3 different kexts that will fix this: A)IntelSpeedStep.kext B)voodoopower.kext C)voodoopowermini.kext...Check out those three and see if they work for you. My motherboard is a Ga-EP45-UD3P Link to comment https://www.insanelymac.com/forum/topic/210825-sl-is-hot-ie-cpu-temp-much-higher-than-leopard/#findComment-1412541 Share on other sites More sharing options...
dino7777 Posted February 19, 2010 Author Share Posted February 19, 2010 Please, can anyone conform this "software" bug. 1. install iStat pro from Apples Widget page 2. run dashboard and take a look at the CPU values you get 3. iStat will ask you to update to the current version 4. run dashboard again, and iStat shows CPU temp values about 10 degrees higher than in 1 Link to comment https://www.insanelymac.com/forum/topic/210825-sl-is-hot-ie-cpu-temp-much-higher-than-leopard/#findComment-1413440 Share on other sites More sharing options...
