I did go out for a night ride last night in the snow, and noticed that my fan had frozen in place until the radiator heated up a bit... I was taking a buddy out for a horror ride in it and went to show him the fan override while it was warming up and the lights just dimmed and the fan didn't kick on when I hit the switch. As soon as I saw 2 bars on the temp guage, I tried the switch again and it kicked on with no problems. Just something to be mindful of. I imagine the fan wouldn't hold out long if the thermostat turned it on and it was frozen up.
