For example. This very laptop (Dell XPS 13z) running Arch linux, if I place it on my lap in such a way that my leg blocks the vent the laptop will gradually rise in temperature until it hits 95C and then BIOS kills the power to the entire laptop to prevent damage.

The same laptop running Windows 7 doing the same thing, also with my leg blocking the vent, will hit 85C and stay there, never shutting down.

^While anecdotal evidence, this isnt a "This happened once, so im telling the story." I had Arch Linux on this laptop for about 8 months or so and would accidentally overheat it at least once a week. I've had Win7 on this thing for about a month now and havent accidentally overheated it even once.

If I ever put arch linux back on this laptop I very well may stick to the powersave governor just to make sure I dont accidentally damage the internals from thermal output
Same for me, but we are not alone https://bbs.archlinux.org/viewtopic.php?id=149901

my post:
same for my Laptop. The temps on archlinux are significantly higher than on Windows. For me thats around 10C difference, too.
I didnt compare it to ubuntu, but I shall do that. Also I will compare the temps of my desktop PC soon (Arch vs Ubuntu vs Windows 7).
I started a similar thread in the German forums some 2 months ago: https://bbs.archlinux.de/viewtopic.php?id=22089

Arch in general seems to be very affected as there is a vast numberof complains about cpu overheating in the forums
