Secondly, the polling time was far too slow for my taste, so changed it to 4 seconds.
Thirdly the temperature adjustment was not to my liking so I've tied it to the actual temperature of the hottest gpu on a card. To do this I've removed the low temp and high temp variables and added a new one called fan_overTemp. My default setting is '10', which thus sets the fanspeed at ten percent over the temperature in degrees C. ==> 70C = 80% fan speed; 80C = 90% fanspeed. This is a simple mechanism but quite effective for me. It of course maxes out at 100%.
Happy mining

any way to make it compatible with lower versions of python like 2.6.x?
