what does that suppose to mean?

they are all already inserted

Code:

~$ modprobe --first-time -a processor thermal fan
WARNING: Module processor already in kernel (builtin).

Fine - Don't mind me - I was feeling grouchy.

I think the solution to this will be in discovering some chip you're not talking to yet.

Maybe clean the dust out. Also, how exactly do you know that the fans are not running at full speed ?

I don't see how this can go together. If your fan is loud it should be running fast, and therefore your CPU's temperature should be low. If it isn't, I would assume that your powersaving isn't set up correctly.

@business_kid: In some cases it really can become handy to monitor temperatures, especially if you are like me and sometimes accidently cover the little slits for cooling on your laptop.

@startover: I have the same problem on my laptop, I can't monitor the fan speed. But that doesn't bother me, because I don't have to. The only important measurement is the CPU temperature, so the first thing to go for should be to get that working. Forget about the fans now, we will get back to that later, if even necessary. Please have a look at /proc/acpi/thermal_zone and look for your CPU. The directory for my CPU for example is named CPUZ. Look into this folder (if there is one and post the files you see.

I don't deny it. I use acpitools.
