Mandriva agrees with your BIOS that your temperature is too high. If Windows show the temperature is lower then either Windows is misreporting the temperature, or else it is throttling the CPU to reduce heat output. Start by cleaning your fan and heatsink. If it is an Athlon install the athcool package and start the athcool service. Athcool puts the Athlon into low power mode when it is idle. It reduces my CPU temp by over 10 deg. If it is an Intel CPU edit /etc/modprobe.preload and insert the text speedstep-centrino cpufreq_powersave freq_table These modules will load at boot and enable CPU throttling on Intel CPUs. (you may need speedstep-ich instead of speedstep-centrino) Then install powersaved from the contrib mirrors and run the powersaved service. Powersaved will scale back the CPU speed whenever the CPU load drops. Its supposed to work on Athlons too, but I have always used athcool instead. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
