The air coming out of my laptops cooling grill seems to be much hotter when I use linux compared to when I use windows. I have no way of proving this because I don't have a CPU temperature monitoring utility in windows. In linux, the monitor says it's at 69 degrees C.
The air coming out feels much hotter when I keep my hand in front the the vents. Is that normal? My CPU is a Celeron M running at 1.5 GHz. I use windows XP and Ubuntu 9.10.
