Man I don't want to hear that. LoL I had design problems on my last setup causing heat issues so I'm revamping it all. I hope it works out. It's not easy to find a fan that will fit in the tight space I have. This was the biggest thinnest fan I could find only 3". I didnt look at any spal fans though. I plan to wire it to run high speed only. I wanted the same controller the OP bought and I listed above but my budget is coming to an end on this car. So I went with a Derale preset temp. Contoller so I would still have the funds for subframe metal. My controller is preset to turn on at 180* then back off at 170*. Which at that temp it may never shut off during the summer here until the cars off.
