Well after reading that, I'm getting the Gords with the fans... I want my junk running COLD! Iced and fanned between runs at track, and during the 100+ degree season. oke:
I wouldn't bother with a heat exchanger with fans. The fans don't seem to do much. I have an LFP in mine now and I can drive 30 minutes or so in town, on the highway, whatever and open the cap and stick my fingers in the antifreeze. It is probably cooler than the air temp outside. All that for $300. Why pay more for the same performance?
