I can't say that I've heard anyone have a sensor fail. Fans yes.

If you do need a fan, here's a post from Arcticchat.

. i went to O'reilly's and bought a 10" electric fan and it works perfect. ive even dove off in some deep mud and water, it is still purrin like a cat.
all for only $53 with a lifetime warranty. i felt better about that than spending $180 from the dealer. NAPA part number CVB758
anyone else got one to add,
carlos
