Comment 134 for bug 370173

I'll add my 2 cents. My laptop, Pentium M 2.0 GHz, is experiencing CPU temps 10-20 degrees C hotter in Jaunty than in Intrepid. My fan is running properly, and actually more in Jaunty because of the higher temperatures. In Intrepid the fan would remain on low or off most of the time, with temps 35-40 idle, but with Jaunty the fan runs on medium or high constantly, with temps 45+ when idle.

The laptop is not overheating and shutting down, but it is definitely running hotter. So there are two separate issues at play: some people are not getting proper fan control. Others have proper fan control, but for a currently-unknown reason are experiencing higher CPU temps in Jaunty, in many cases leading to shutdowns even with the fan running on max.

In Intrepid my CPU temp never went over 69 C, whereas in Jaunty it regularly shoots up to 79 C. I luck out because my fan prevents it from going so high to initiate a shutdown. There are enough people working on debugging and I don't have time to install/test multiple kernels. My point is that this bug should be tackled as two issues: (1) fan problems, and (2) something unknown in Jaunty that is causing higher CPU temps separate from fan issues.
