Current update. Problem is repeatable on 4.20.3-042003-generic kernel build with latest 415 nvidia driver. Problem of overheating can be solved partially by using thinkfan utility and editing /etc/thinkfan.conf (0, 0, 45) (1, 38, 50) (2, 40, 61) (3, 52, 63) (4, 56, 65) (5, 59, 66) (7, 63, 78) (127, 70, 32767) <- 127 gives full speed of fan and level:disengaged (it is about 4000 rpm)
second fan is under nvidia control and running slowly even on 100% CPU load and 88C degree. probably can be solved by tuning nvidia drivers or settings, but ... I did not found how. Right now tried to build large project, all cores are 100% and 85-90 degrees, nvidia only 52 and fan moves slowly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1800838 Title: Lenovo P52 laptop fan control incorrect Status in acpi package in Ubuntu: Confirmed Status in linux package in Ubuntu: Incomplete Bug description: Pure system ubuntu 18.04.1 with all update running on Lenovo p52 laptop.
