Have you tried different pwm and threshold values in thermal.h?

Not yet. I haven't tried the Chromebox in its final location yet since I've been screwing around with other aspects of this OpenELEC project, like backlight dimming on the 7" 1280x800 LCD I got from Adafruit and some various tag clean up of my library. I figured I would look into tackling the fan profile if I find it obtrusive once I get it setup in my great room with my main stereo. The inability to preview the changes prior to reflashing the BIOS has me a little hesitant. I'm used to working on embedded systems with an on chip debugger where you can test on the fly and it's impossible to brick it.
