I guess you should also try other fan speeds too, report back when you have tried. The expected result would be for the fan to barely spin at 10% and gradually spin up until reaching 100%. At 100%, the noise should be quite loud. If this is the behaviour you see, then I would like you to set the fan mode to automatic (mode 2) and monitor the fan speed set by Nouveau by reading pwm1. If the fan speed does not change with temperature, it would be useful to paste here kernel logs with nouveau.debug="ptherm=debug" set in your kernel command line (you can edit this from grub directly, when booting up).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
