I did discover yesterday that the fan of my GPU spins relatively slow under high load. When the GPU reached ~80 degrees Celsius, the fan didn't even spin at half the maximum RPM! I used the pwmconfig script and the fancontrol service from lm_sensors to force the fan to go to the maximum RPM just before reaching 80 degrees Celsius. It's very noisy, *but* the GPU stays well below 70 degrees Celsius now, even under heavy load. As this issue seems to occur only when the GPU is hotter then ~75 degrees Celsius, I'm hoping that this will help in preventing the problem. I'm still confused as to why this is at all necessary, the critical temperature is 91, so why do I encounter these issues at ~80? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
