keplenk Posted February 6, 2008 Share Posted February 6, 2008 Hi all, I've successfully installed Leopard and XP (dual) in my system. I have an E2180 processor and GA-P35-DS3L motherboard. All hardware is running at stock speed. I'm now having some heat issues. I noticed that when I'm in Windows XP and ran CoreTemp + SpeedFan 3.34 beta 38 my system runs 33 Celcius (idle) and 53 (full load). Which made me very happy Now when I booted to Leopard (kalyway), I installed ThermalMonitor and noticed that my temps run differently from Windows. In Leopard, my system runs 48C @ idle. it runs 67C @ full load!!!! Why is that? 15 C difference!!!??? I've checked my Extensions folder and noticed that the AppleIntelCPUManagement.kext is not there. I've also tried using different mach_kernel (speedstep) but it did not help. What can I do to cool my system. I need this to be 33C because I'm planning to overclock my system soon. Any help would be appreciated. Thanks.

Looks like you must have missed my post replying to you in the How to install on Gigabyte boards thread the short of it is it looks like the programs calculation is based on a revision G chip not the B you have of which the G is 15C higher max temp so the B chips show up with a higher temp because of this. Edit: If you use Speedfan on a revision G it is off by the same 15C in windows.

But they said that this was fixed in the 4.34beta38 version. I'm not that familiar with the G or B chips. But what do you think is my true cpu temp? The one in Windows or OSX? If the real CPU temp is 48C @ idle, isn't it too hot? I hope the real one is the one in Windows What do you think? Thanks man!

For the revision G vs B chips pretty much all CPUs have what is called a stepping (version) this is the die used to make them when the manufacturer makes a change to the die the is it call a revision and the chips are labled with this new stepping for the Core2Duo there have been If I recall correctly the versions B1, B2, B3 and G0 now the next one if they do it will most likely be G1. Edit: I should tell why this makes a difference in the temperatures with a B chip the tjunction I think it is called is 85C with a G chip it is 100C hence the 15C difference in temperature monitor as I think it is calculating its temperatures using the higher base so you end up with the 15C higher for a B chip using it.

keplenk Posted February 6, 2008 Author Share Posted February 6, 2008 Thank you sir, for the informative response I now feel relieved Try the beta of speedfan if you want .. I think it fixed that 15C problem But I cant be sure for I am confused with the stepping and stuff ... lol http://www.softpedia.com/get/System/System.../SpeedFan.shtml You've been very helpful :) Link to comment https://www.insanelymac.com/forum/topic/86078-heat-issues-in-my-ga-p35-ds3l-rev-20-leopard-1051-kalyway/#findComment-611818 Share on other sites More sharing options...
