Guest dally Posted May 20, 2006 Report Share Posted May 20, 2006 After the installation of Mandriva 2006.0 my CPU fan keeps running without any breaks. When I switch to Windows XP Home Edition, or my Fedora Core 5 installation everything looks fine. CPU fan stops after some short time and then starts when my CPU needs it. Any ideas why Mandriva 2006.0 installation keeps the CPU fan cooler running?

coverup Posted May 21, 2006 Report Share Posted May 21, 2006 Since Fedora Core 5 installation works fine, compare what services/kernel modules are being used by Fedora and Mandrake. Also, check CPU temperature, frequency and ACPI settings. Fans are controlled by kernel modules, so it may be that these modules are different, or not loaded in Mandriva. In particular, consider using cpufreqd, cpudyn or powernowd daemons for controlling CPU frequency. My intel centrino laptop was running pretty hot until I noticed that it was constantly running at 1600 Mhz, even when the CPU was idle. Loading the speedstep-centrino module and letting the frequency be controlled by cpufreqd and cpudynd daemons, helped a lot. Quote Link to comment Share on other sites More sharing options...
nchancock Posted May 21, 2006 Report Share Posted May 21, 2006 just to clarify, to check what modules are loaded type "lsmod | more" at the commandline. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted May 21, 2006 Report Share Posted May 21, 2006 You might have to go into System/Configuration/Configure Your Desktop/Power Control and enable the features in there too, although usually most of this is for battery settings relating to laptops, so you may not see anything in here if a desktop. Just an idea, just in case. You can check if cpufreq is installed with: rpm -qa | grep cpufreq or to check if it's enabled as a service: chkconfig --list cpufreq Quote Link to comment Share on other sites More sharing options...

He has Mobile CPU, that's why I suggested looking at frequency stepping. Adjusting power setting is a very delicate thing, I would not trust "one hat fits all" GUIs on this. A much better fine tuning can be achieved by editing scripts following recommendations in the README files. Quote Link to comment Share on other sites More sharing options...
