For the fans, my car is running Mirriah motors and fan blade in stock location. It also has a sucker fan on the back (not sure how much that does, but I believe Hall used to sell their rads with this fan as I’ve seen a few of the same setups)
The car spent most of its life in San Diego area running off just a dash operated switch. Now in Massachusetts, the fans typically operate only at 50% according to the controller leds.
