    CPU Temp.


    Would anyone have any idea to why my cpu runs cooler with Linux than Windows? I have no clue to why its cooler with Linux but it is, along with chip set temps.

    Perhaps you have more programs running in windows? Less load == less temperature.

    I run both on my desktop, and there is no difference in temperature between the two. For linux, I use Gentoo with a lot of extra goodies running(such as X and gnome), which is probably why my temp is more equivalent to my windows temp.

    I was thanking it may have something to do with that but I wasn't to sure though, I've just got into using Linux so I'm not real sure of its workings. Thanks for your reply

    Always happy to add my opinion

    I'm a recent convert myself, and I have to say, I learned loads, pardon the pun, more about computers in the first month of using linux than I did with years of using Windows. Stick with it, it's definitely worth it.

    do you have fan speed control enabled in the BIOS, and i am guessing that to measure the temp in linux you used lm_sensors right? well on some motherboards (such as the pc4800-dlx) lm_sensors messes with the BIOS fan control and it kicks the fan to 100% all the time (even at idle), windows does not do this and that would cause the temp difference

    for those motherboards with the affected temp sensors there is a way to fix it (only really needed if you have a loud CPU fan like me), but i can't find it right now

    Well I'm running dual Intel Xeons and the board doesn't control fan speed, its the same speed all the time. When I run windows on it the cup temps run close to 60c and with Linux they run a little over 40c. I understand what you were talking about but the board doesn't control the fan speed, the only thing I could possibly thank of that would do it is less processes running in the background, but thats just a guess

    Been told its because the Linux kernel uses halt instructions much more than Windows.
