Inspiron 6000 CPU Fan Uses One Speed


Hello all,

I have an Inspiron 6000 and I can hear the fan spinning, but it seems it only has one speed. In Windows the fan will get a lot louder when I'm doing CPU intensive work. I have yet to have my laptop lock up or restart on me, but this is my only computer and I just want to make sure I'm not risking it over-heating.

Is the fan only using one speed because Linux is keeping the CPU cooler than Windows does or do I need to add different fan profiles or something similar to what I did got cpufreqd?

Also, at one temperature should I start being concerned with it over heating? When idling it tends to stayaround 38-40C. I was just compiling and kernel and downloading something and it went up to 57-59C.

Thanks,
Chryzmo

You should use a cpu clock speed controlling daemon, such as "cpufreqd" or "powernowd". Make sure you load the necessary modules. You can use my page as a reference:

Check out especially sections "2. The hardware" and "5.2. CPU frequency scaling"
