I am currently running a koyorad radiator with dual 12" FAL fans. I just have the fans wired up to a switch where I can manually turn them on/off. While at the track this weekend after a couple runs and waiting in line my car would begin to overheat. My fans would keep cutting in an out as the car got hotter and hotter. I would take it back to the pits, check all the wiring, and they would still cut in an out. Any ideas, or possible reasons this could be happening.

At 1 point in the day my defi temp gauge would read 228 degress, definately getting up there. I also have the sensor for the gauge tapped into the upper radiator hose.
