Check /sys/devices/platform/windfarm.0/*, the files in there should show you the fan speeds and temperatures.
Great, I can see them now. Thanks a lot! Where can I get the limits? I've seen the temperature go up to 70 without getting the fan sound I had before. I don't have MacOSX so I don't know if the fan ever goes full speed with that system. From what other (Mac) users tell me it does not happen often. Since the support for this is new I just want to make sure that the fan will work when the time comes. I'd love to force the situation, but I simply don't know how ... Current readings: cpu_fan:2067 cpu_power:10.662 cpu_temp:67.166 Thanks, Eduardo.
