Why not an option of programable turn-on temp. of MMM

[simplechamp]

I would think the temp could be changed via software. A thermistor just changes in resistance as temp changes, so you could set the fan to trigger at any resistance (really it would be the voltage drop across the thermistor being measured). I don't think CC would want to do that though. They've probably spent plenty of time researching and deciding that 150F is a good temp for the fan to turn on. Some people would have the fan turn on at lower temp, and that would be no problem. But some people would set the fan to turn on at higher temps or not at all, and that would make a bunch of warranty issues and headaches for CC.
