I have a Dell Inspiron 1440 laptop that's been very noisy since I installed Natty. When idle in Maverick, the fans would usually spin all the way down. When idle in Natty, the fans are 2 or even 3 steps above their baseline and the laptop gets unusually warm. I've heard that kernels above .38 have a power regression; would that contribute to an overall increase in the computer's temperature? On average the laptop uses 20-30% CPU, so I installed cpufrequtils and set both cores to powersave, but that didn't seem to help. Here's the output from lm-sensors:
and the output from cpufreq-info
Any advice on cooling down my laptop, even if it means downgrading the kernel, would be appreciated. Thanks
