h1. How to fix overheating on ThinkPad X201 Problem: My Thinkpad used to heat up well over 100C when more than one core was under heavy load.Installing "thinkfan":http://thinkfan.sourceforge.net/ allowed to turn off fans when they were not needed, but didn't help otherwise. Problem source: Besides 0-7 fan speeds, there's also "disengaged" mode which allows to reach ~5800 RPM compared to 4800 for 7. Default thinkfan config and auto mode do not use it for some reason. Solution: Add a section with "level disengaged" mode to default thinkfan.conf: bc. (0, 0, 55) (1, 48, 60) (2, 50, 61) (3, 52, 63) (4, 56, 65) (5, 59, 66) (6, 65, 78) (7, 77, 90) ("level disengaged", 80, 32767)
