Can anyone recommend a fan controller for a Spal VA164-ABL806HT/R-116A
I got a harness and relay kit from CE Auto Electric to power my dual 11 inch Spal fans. Very nice kit. I use this one here:
70A Dual Fan Relay Kit – EFI Applications, Negative Trigger.
But they have a bunch of other ones for just about any application.

I'm pretty sure this fan can pull about 100 amps, I suppose I could use the dual controller and split the 8 gauge wire the fan comes with to 2, 10 gauge wires and run the controller as a single unit.
What I'm really looking for is for a variable speed controller so the fan doesn't have to run balls to the wall if only a 50% load is required.

That will probably pull the car down the road like a propeller on a airplane lol.
That fan has an integrated controller. It’s designed to be hooked direct to battery with a circuit breaker or large fuse then the white wire gets a pwm signal from an ecu or other controller. Lots of guys are building their own from arduinos if your ecu doesn’t have a negative pwm output.
In the efficiency at max speed table is maxes out at 77a so I’d probably use 120a.
I’m personally not a fan of fuses and prefer this style circuit breaker for an application like this
It lets you kill power manually if needed without removing any fasteners and also won’t leave you stranded if you don’t have a new fuse and the wrenches to replace it.

True dat. I have used those breakers in a few places and liked them but if they are prone to failure that’s a good data point for us to be aware of.
