Questions:

a) What is the actual resistance in ohms of the OEM fan and the replacement fan if measured across the contacts.
b) Have you changed the bad resistor yet? If not why not?
c) Same question of measured resistance on the lower current fan that does not trip into protection mode?

Suggestions:

a) Replace all the out-of-spec resistors with correct replacements. Think long and hard before upping the wattage if there is any chance that the resistor may also act as a fuse under extreme conditions.
b) Perhaps a small thermistor on the fan line might reduce the overload trip - meaning that what the fan pulls running may be much less than what it takes to start it.
