Ubuntu runs hotter than Debian

Now that I’m religiously checking CPU temperature on the $0 Laptop (the Gateway Solo 1450) and found out that Knoppix 5.1.1 runs cooler (about 50 to 55 C) than Ubuntu (55-65 C) in preliminary tests, I thought I’d test Debian Etch. Temps for Etch are the same as Knoppix, which follows, since Knoppix is based on Debian.
