Bonjour,

I have a asus p5wd2 premium mobo and I wonder how control temperatures
and fan speeds.

there is nothing in /proc/acpi/thermal_zone .../fan

I used gkrellm

this gives me 3 temperatures: I cannot know which is which... average of
temp1 is 40°C, temp2 is 55°C and temp3 125°C

How can I know what is measured by these temperatures?

gkrellm gives me also 4 fans: only one is working, CPU fan I think. How
can I get the others working: I have 3 more fans installed on my tower
(Antec P180) and is it possible (and how?) to controll all fans speed
according to the remperatures in the tower.

I run  2.6.14-1.1653_FC4smp kernel and there are no fan, processor,
thermal.... modules available; are these modules necessary to control
all these hardwares and, if yes, how can I compile them for my kernel? I
read http://fedora.redhat.com/docs/release-notes/fc4/errata/#sn-kernel

"7.2.2.4. Building Only Kernel Modules"

but did not understand how to build the correct Makefile to compile,
say, the thermal module: changing what is to be changed in the given
example, I get a "nothing to do for default" as a result....

When compiling some program, I recently got this message:

  CPU1: Temperature above threshold, cpu clock throttled

Which I don't really understand... "cpu clock throttled" what is the
exact meaning and where is the cpu clock defined?

Last question: I cannot start cpuspeed service, how can I do that and
how to configure this service.

Thank you for (detailed) answers, I don't know much about hardware and
controll of it by the kernel.
