I have set the parameter -tt 65 but it doesn't seem to adjust the fan speed? They seem to want to stay around 25% I am using ubuntu 16.04 so no Afterburner fan curve.

Setting -fanmin 50 doesn't set minimum speed to 50% for fans

Edit: just realized that it says the fan controls are for windows only. I am on ubuntu, what are people here using to control fan speed on linux ?
