Hi Jean, thanks for testing and patching pwmconfig. Regarding the tempsensor issue, does the same thing happen if you change PWM values manually? > Additionally, pwmconfig does not work for me, but maybe that's just my > system not supporting it. You mean your fans don't respond to PWM changes? There's a high chance your mainboard has no support, maybe this page has some info on it: http://www.almico.com/forumindex.php If you're a bit crazy, you could add the fan control circuit yourself, then my homepage may be of use for you: http://www.hdev.de Regards, Marius
