On Ubuntu 14.04, I created the following /etc/sensors3.conf and applied it with sensors -s. The output of sensors is now correct, but suddenly the case fan started running at 100% and I can't get it to stop (other than turning off the machine). There are only 3 fans in the machine: the case, the PSU and the CPU. Can the sensor config cause the fan controller to misunderstand component temperatures? I didn't use command fancontrol at all. How do I get the fan back to normal?
