    Windows 8 running hotter than 7?

    Hello! I just installed and am running Windows 8 on a recently purchased Sager NP8690. While running Windows 7, CPU idle temps were typically 45-50c and while rendering video or in game it'd peak at 75c. After installing 8, in a clean install, I'm seeing temps idling at 55-60c, and peaking at 95c while rendering video or playing a game.

    My question is, could this be related to the OS utilizing the CPU in a way I'm not familiar with, or is it not reading temps correctly from the motherboard? A few places I've checked, other users have experienced the same problem, and claim a lack of Win8 compatibility with motherboard BIOS. This seems possible to me, as I'm still using the stock BIOS, but I was wondering if there were any other known cases of this?

    I noticed same thing on win 8, temps are higher than on xp. But in my case it was less than 5*C, but not only cpu but everything, cpu, mobo, hard drives and gpu. Also you have to consider temperature in the room.

This isn't a technical thread as such. Just wondering if any of you are still running Windows 8.0 instead of 8.1? Don't get me wrong, I do realise that Windows 8.0 will be going out of support in January 2016, chances are Windows 9 should be out by then so that should be a suitable upgrade....

I've done considerable research on this and still can't find the exact Windows 8 process that causes this. PROBLEM: There is a service host process that keeps the CPU busy (12%), and consequently causes my computer to run warmer than it does under Windows 7. About 15 degrees Celsius warmer. If I...
