Nope, the product description I found on the Summit Racing website shows it to be a brushed fan motor,

so the controller I bought should work fine. I'm going to set it at a lower speed for start up, and then turn the speed up in traffic, for a higher speed and more cfm's. On the highway, I'll turn it back down, though.

The controller has over twice the amp rating that my fan is supposed to draw at max, so it probably won't have a problem. I bought this unit because it

• 1) has mostly high reviews,
• 2) is compact and self-contained (after I opened the case and installed the forward-stop-reverse switch and potentiometer), easy to mount in easy reach, and
• 3) has a speed% display on it.

At $22, it's a start, and if it fails, I guess I'll have to upgrade. If, for some reason, my fan motor gets fried, I might try and modify an aftermarket "brushless" fan to fit in place of the Flexalite. All the brushless universal fans I've found (with good CFM ratings) are priced sky-high, and not a choice. But...

I think I could fit a TOPAZ 64546921381 Auxiliary Condenser Brushless Cooling Fan Assembly for BMW X5 2000-2006 into the space behind the radiator (modified to fit, flow reversed), and it could be sisterred to the factory auxiliary fan. Maybe they could both be controlled by the OEM circuitry?

Last alternative, I could always install a new viscous fan assembly for about $100-125, but I'd also want to install a Stewart water pump before that (my water pump probably wouldn't last too long with a visous fan attached). Hopefully, my fan controller will work as designed, and as I hope for all my projects "it might just work" (I've put similar stickers on my home-built trailer, which is a bit out-of the-ordinary, but works)....
