Yes, just learned last night that there is an option that you can manually put in through /etc/X11/xorg.conf called Coolbits (nVid only) that gives you 100% control of fan speed..... unlick MSI Afterburner (on WinBlows) though, it doesn’t change by heat... it is a % thing only :/
OH, btw, my VidCard heat is 20 degrees Celsius lower on Linux than Win (running at default 40%.... Linux -46/Win 68)
