Just tried out the kernel as per instructions Linux HomeMegaUbuntu 4.3.0-040300-generic #201511020949 SMP Mon Nov 2 14:50:44 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
echo 200 > /sys/class/hwmon/hwmon3/pwm1 echo 70 > /sys/class/hwmon/hwmon3/pwm1 results in the erratic fan speed. if no erratic behaviour wait for a few hours (seems to be about 4 -5hours) and the erratic fan behaviour starts. to stop it echo 200 > /sys/class/hwmon/hwmon3/pwm1 echo 70 > /sys/class/hwmon/hwmon3/pwm1 seems to work for me for a few hours before it starts up again. Interesting that echo 200 > /sys/class/hwmon/hwmon3/pwm1 results in high CPU fan speed with slow changes in erratic fan (as shown above) superimposed on top of high fan speed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1514052 Title: erratic fan speed and little control kernel 4.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1514052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
