    Default 83 C on Quad Q9400 HackPro

    Hi all,
    I'm experiencing overheating problems since I've updated my Hackintosh from Dual to Quad core.
    I'll try to explain my issues as briefly as I'll can.
    I've a ThermalTake Soprano Vx case with a rear 12 cm fan connected to the MB and the usual cpu fan over my Q9400.
    They seems to spinning all the time but it seems not to accellerate when I start some 3d renders that rise the temperature from the usual 45/50 to 83 C. My HackPro is up and running 24/7 and soon will be Summer with high room temperatures, so I'm worried about frying my CPU. There's any way to control the speed of the fans without hacking the kernel or install kext that could damage my perfectly stable system? My OS is a Retail Leo 10.5.7 installation

    Thank in advance for any help you can give me.

    Hi there,
    That is a bit too warm.
    You will be able to fry some eggs there soon.
    What is your motherboard model? And your CPU fan?
    Have not run across this issue with OSX, but certainly looks strange.
    Regards,

    Default 83C on Quad Q9400 Hack Pro

    My MB is an ASUS P5KC. I've gone mad to make it stable so I'm scared to death to mess up with kernels or kext. The cpu fan is the one inside the original intel box.
    Ooops You rang my bell
    Could it be that, 'cause I've changed the CPU myself I've not put enough thermal compound on the CPU, or I've not enough tighten the fan?

    Thanks so much for the answer

    Hi,
    I would use good thermal compound. The stock intel fan is ok for general use, but for intensive CPU application you should replace with better one (much better one in your case). That temperature, if reported correctly by whatever utility you used, will fry your CPU shortly.
    I don't think OSX have a lot to do with that temp. Any times intensive CPU applications, 3D/video rendering, are used the temperature will raise up, in any OS not just OSX.
    Hope this help.
    Regards,

    Take the Scythe Yasya, this is a very efficient cooler. i dunno if it works with the sockel of your cpu (i am lazy) but have a look at it. this cooler will keep the temperature far below 70 degrees celsius, even at lowest fan speed.

    Lightbulb Thanks

    I'll check it out. In the meantime I'll add more compound on the back of the cpu heatsink to see if it will low the temperature.
    BTW disabling some cpu features that I'm quite sure I'm not using (speedstep and vandervort) the temperature is lowered around 42 C instead of the usual 49 C with minimal CPU activity.
    Thanks to anyone for the help
