Mine is a 3 row and it cools great with the dual Spal fans. Even on a hot Texas summer day in 5PM heavy city traffic with A/C on, it stays under 195.
I'm controlling the fans with a 2-speed setup using 3 relays and a Dakota 2750 controller. I'm also using a trinary switch on the A/C system which turns the fan onto high speed when the high-side pressure gets to a certain pressure. The Dakota controller has an input for hooking up a trinary switch lead.
Btw, I would not buy my fans from Ledfoot. They couldn't even tell me what brand they sold. So I bought my fans separately. Through the years I have had many troubles with offshore made fans and now I will only use Spal or Maradyne.
SPAL is one of the best when it comes to electric fans. do you have a specific self-made setup for controlling the fan speed, or was it a ready-made solution?
