Electric cooling fans - Two pullers or One pusher?

Recommended Posts

I was sad to see SPAL stop production of their super fan controller, the one that had soft start, built in timer, multiple fan capability, etc. I spoke with a rep of theirs at SEMA and he said they just had too many problems with it.

 

That's what I want. Something that can handle all of those functions.

FiTech EFI does a good job controlling dual fans, independently.  Not many "cheap" controllers can do that.  They can't handle the Amp load.

A stand alone ECU is kind of out of the question for many Datsun owners.

I run a separate 30a relay for each of my fans on the 620, and 80 amp relays on my Cressida.

Never a problem....

When using a fancy, multi-function fan controller, I always just use them just to turn on & off secondary relays.

Very little amp draw to turn on another relay, and if something fails, and over loads the system, such as a fan failure, the secondary relay takes the abuse.

The controller never takes the death blow.

I wouldn't see a problem with that. Did you see the links to the fan wiring I posted earlier? Did you do something like that?
