My Lenovo Z50 overheated under Linux. I tried Ubuntu 16.04, 18.04 and Linux Mint 18.1. The standard installed Windows 8 doesn't have this problem. It heats up to 100°C and shuts down. I followed the temperature with psensor to see it. I think the fan is every time on the lowest level. I tried fancontrol but it can't find the fan. Can someone please help me?
