I've got the two high speed radiator fans wired to a switch and I run it whenever I am on track, it really does help to keep things cool. A side effect is that I have now picked up pending code, something to do with the fans, the car knows that something is up, but it doesn't set a CEL so I don't worry about it. Here's a couple of approaches to possibly resolve this, but since it doesn't set the CEL I don't worry about it.
