Ive recently builded a (almost) fanless little server around a EPIA LN10000EG with a VIA C7 1GHZ fanless, a little case with a 60W PSU and a desktop (3.5") HD. The case has a small and loud fan, that I plugged in as cpu fan. Im using a C7-compiled-for version of Ubuntu 8.04 server kernel (2.6.24-17-server). Ive compiled the kernel for C7, using e_powersaver, acpi=force, hpet=force (powertop is showing 2-3 wakeups per second, cool, but my cpu isnt entering C3, only C2. but that is another problem). VT1211 has pwm fan control, but I dont know what temperature is driving the "auto control", and the unique variation that I can get is fully on with auto control turned off and completely turned off with auto control turned on (echo 2). So I hacked a little cronjob that turns auto control on and off to indirectly turn fan off and on using the temp2 result of sensors (the unique temperature that appears sane) until a better solution is found. My goal is to configure the fan control map to never trigger "full trottle" of the fan. What is the temperature that are controlling the fan auto control? Sergio Bruder
