Hello,

I'm using ubuntu on Toshiba Tecra M3. My fan is constantly working hard
and making noise. When Windows XP was installed, it controlled the fan
activity based on the CPU usage well. So I want the equivalent
performance on linux as well. I monitored the CPU activity on linux and
it is controlled well. So the problem is that even when CPU is not used
much, the fan activity does not come down. What should I do? Please
help me.

Those Tosihba models I have seen all have BIOS option for different fan
modes. You may look if you have it too.

There is a program to turn fan on/off included in toshutils (it won't work
for all models). It is possible to write a small script that will monitor
CPU temp and switch fan on/off respectively.

Finally you can ask Toshiba to publish interfaces used by Windows program;
in this case someone may be able to write program that switches fan mode on
the fly ...

I installed toshutils and found out something strange. I think my fan
control actually works during first 10 min (about) [without doing
anything]. But after 10 min, there is no return.

Likewise, I can manually controll the fan speed by using toshutils
during first 10 min, but after 10 min, toshutils doesn't do anything.

Sounds thermal?

What is CPU temp? Perhaps fan is choked on dust bunnies? CPU temp
too high == fan full speed.

How do I find out the temp? It appears I can't use lm-sensors.
