I have never seen a car fan that pulled that kind of amperage so I called B.S.
When the fan arrived I tested it. 11 amps was the max I could get it to pull.
Coach send the fan back and bought a different brand.

Why do some car manufacturers use 70 amp relays, because 30 or 40 amp relays don't have the metal cross sectional area for the high current terminals.
I would always rather over-engineer, than a have a fire.
