Magnum cooling

That should be enough CFM to feel them pulling air a few feet in front of the radiator, no? Try lowering the temperature they start at. There are several companies that make staggered and soft-start harnesses to reduce the amperage draw on start up.

They seem like they move quite a bit of air. I’m concerned that lowering their start temp would have them running nearly all the time.

I think they’re only supposed to be operating intermittently
