I see what you are saying. It would be easy for it to come on at 65c instead, but maybe you would need to mount the temperature sensor closer to a mosfet to get a quicker response? I remember Ian down in Australia was using a Curtis 500amp controller with his direct drive conversion and it blew up after a short time because it was the equivalent of driving around in a high gear I think with a large motor. I'm not sure how fast of a response you can get without putting the sensor actually embedded in the back metal case of a mosfet which Otmar (who makes the zilla) has actually done.
