I disagree. The temperature read out of lm_sensors has to be set up for each motherboard. The readings from an install of lm_sensors is often wildly inaccurate. The mobo manufacturer will have set up the BIOS temp readings to be accurate (if they have done their job properly) When configuring lm_sensors the readout should be compared to the BIOS and a temperature probe if available.

This is why, using athcool as an example, the author > issues this disclaimer : True, both Athcool and speedstepping will cause the CPU temperature to vary, but that is better than having the OPs computer shut itself down after 30 mins. I note also that Athcool's author does not list "Core trace migration" as a risk when using athcool. > Before use athcool, you must recognize these potential DANGERS. > Please use athcool AT YOUR OWN RISK. > Athcool does not work on all mobos and versions of Athlon. I have an old Athlon T-Bird where it makes the system unstable. Most recent Athlon mobos should work fine. After all athcool is simply using the feature AMD put into the Athlon for the purpose of reducing power consumption. Are you saying AMD do not know about CPUs ? Where I do agree with you is for the need of the CPU heatsink and case cooling to be adequate for the heat produced at full load. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
