Default Dominator PWM Fan Control

Hey guys I'm looking for some insight from the Holley guys. I'm gonna be going to brushless cooling fans and want to take advantage of variable speed control what are you guys using for your PWM tables?? I was kinda looking at going with a CTS vs Speed table but honestly have no idea what the best strategy would be.

The brushless fans, variable speed, PWM stuff is another new thing to me. I've got no AC in the car or really any other creature comforts so it's just the cooling fans. Let me know what's working good for you guys. Any and all opinions are welcome. Thanks everybody!

CTS vs. Speed would work fine. Most OEMs disable the fans at around 65 MPH.

Have mine 0% upto 206* then 70% at 207 then 80% at 214 and 90% 220 and above.

Works great

Perfect! Thanks. That's where my thoughts were heading seems pointless to have fans running with any kind of real speed

I see I see you run things a little on the warmer side.

It feels stronger warmer.

I'm running chevy volt fans in mine. They are beast. Much better than my previous setup.
it never really gets above 210ish... mostly hovers between 203 to 209 with those settings. Fans never run very long

I think I also have mine off above a certain mph...50 maybe

Yea I've heard that fan is wild work. I guess I'll just have to get the fans in and start playing with it to see where it ends up. But I'll definitely turn the fans off at any real speed. Thank you sir for the input

I just did chevy volt fans...they are really impressive for the size. I dont remember off the top of my head what flow but I did test them with my fan testing setup and it was a lot.
