So i've been messing with the maxima fans. Here are the results i got.

When i put Blue and Green to positive, with yellow and black to negative the fans spin SUPER FAST in pulling direction. When i remove any wire(neg or positive) the fans spin "slow".

I have a generic temperature controlled fan controller. The controller has its own relay which reads

TIANBO
NO:40A 14vdc
NO:50A 14vdc
TRV4-L-12V-Z

The fan controller has TWO leads for fans. One orange(fan 1) and one blue(fan 2). My plans are to connect the orange power to one fan and the blue power to the other fan . Each fan will have both positive leads connected together and both negative leads connected together, leaving the fan in HIGH mode whenever powered on.

Providing i connect my fan controller to a 12v source(directly to the battery), will this single relay(which is built into the fan relay) be enough for my setup? The fans WILL NOT be running at all times, only when temps reach 190 or so. When the fans do come on they will be both be full blast.

DO those plans sound ok and electrically safe? i am an electrical idiot, so any input/advice from EXPERIENCED people would be of great help.
