Please let me know, which additional information might be needed. I honestly don’t dare to go further on my own and help from the community is much appreciated. But where is the fan? Is it not a cooling device? Or is it listed somewhere else? In the process I came across /sys/class/thermal:Ĭooling_device0 through cooling_device3 all only list ‘Processor’ in the file ‘Device’Ĭooling_device4 lists ‘intel_powerclamp’, at least. So I tried editing the thermald configuration, even though I read that thermald is buggy on Haswell architectures, which my chip is.

If I use the discrete nvidia card via bumblebee’s optirun for a 3D game it can go up to 90dC. Temperature under normal work load is in the range of 60-70dC, which I find already a bit much.
