Hello, I am a tumbleweed user, and I have recently (since 20150421 or 20150422) been having issues with my laptop's CPU overheating. Most of the times, the fan does not change speed when the temperature increases, and I cannot control its speed manually with pwm1_enable set to 1. I reported it on the factory mailing list, and together we could rule out the possibility of a hardware failure (most likely dust on the fan). In particular, through some (seemingly) random changes, I could get the fan to work under manual control. This setting does not appear to be reliably persistent upon reboot, but it proves that the fan can still spin fast enough to cool down the CPU, when the OS has full control on its speed. The setting I have to mess with to reactivate the fan when it stops working is the "thermal.off=1" parameter of the kernel. I would like to be more accurate, but I can't : in the past few days, I have "reactivated" the fan control twice, and as far as I can tell the procedure was not the same (and the same procedure did not yield the same consequences every time). For reference, the factory thread is here: http://lists.opensuse.org/opensuse-factory/2015-04/msg00299.html In particular, I had gathered some information about my hardware on: https://gist.github.com/ThibautVerron/27da7b4da3940f9894c0 If some of this information is irrelevant, or some other is missing, don't hesitate to ask of course.
