Efans-Pusher or Puller?
I would have to hunt too hard to find out.
Are Efan kits pusher, or puller.
And yes, I am frankenstein-ing a kit, based on all the recommendations-and damnations of forum members.
I'm liking SPAL, and I'm thinking about hardwiring the controller(S) to the inside of the firewall.
All connections soldered, and properly sized wire.
Anybody see a problem with extending controller wires in a harness, to get up front to the radiator?

Pullers.
SPAL fans move an enormous amount of air and are quite loud for doing so. I have 2 16" fans "sitting around" waiting for someone to buy them with low hours.
And whatever you do, do NOT get the SPAL PWM. I went through two of them in a week before i sold my old F150; putting the fan clutch back on.

Ok,
I solved the pusher/puller problem with Maradyne Fans, which have reversible fan blades.
While there, I found some simple temp sensors and relays.
I was wondering-the biggest problem for the controller crowd is that they have variable-speed controllers.
Although a cool feature-is this too delicate a feature to have for under hood?
I'm thinking that just ON/OFF relays with preset temperature thresholds might be the simplest, most dependable set-up.
And while measuring stuff out yesterday, I was wondering why I am not putting fans on the condenser coil too. NOTE: I'm in Phoenix, and sitting in traffic gives me an ambient temp of 130 easily.
Thoughts?

i have dual fans pulling on my truck.
total spent on everything was about $75
