Everything I've read states that the fan should be coming on at about 150 degrees. From what I can tell, my fan comes on somewhere between 75-85 degrees. Based on what I've read, I'm assuming that the, "Is this normal?" question would be answered as a no. My concern is more geared toward is this a problem?

My current gearing is 19/68 (stock), but I have a 20 and a 22 Pinion coming in tomorrow and a 58 spur I'm waiting to install. I don't want to have any over-gearing issues. (Running Zippys, 6S, 20-30c, 5000mah).

Thoughts?
