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. -- François Patte UFR de mathématiques et informatique Université René Descartes http://www.math-info.univ-paris5.fr/~patte
