Centrino fan working too often!

I got a Centrino laptop, HP zt3010us & i installed linux on it. everything went smoothly, but the processor fan is working more frequently than under window$. running top doesn't show more than 2-3% processor usage.
so i am wondering if other users are experiencing something like this or is it just me?

any tips what can i do about it?

do you have speedstep enabled in the kernel along with a program to underclock your cpu?

Re: Centrino fan working too often!

i have the stock kernel 2.6.7 installed. i have no clue if speedstep is enabled!  :?

does it mean it is installed?

# CPUFreq processor drivers
#
CONFIG_X86_SPEEDSTEP_CENTRINO=m
CONFIG_X86_SPEEDSTEP_CENTRINO_TABLE=y

that's in your .config by default you need to load speedstep-centrino and get something like cpudyn or cpufreqd that will downstep the speed of your processor. I think cpudyn will do it dynamically while cpufreqd you have to tell it to downstep your proceessor.
