Got the resistor pack solution all sorted out and approved by multiple PCB specialists. Going to get two heatsinks that are big enough to cover the board and Dremel out wells in the burface to make clearance for the resistors. To secure them, I'm going to use some Arctic Alumina Epoxy. Fill the wells I drilled with it and slather the rest of the heatsink surface with it, then make a PCB sammich. The epoxy will keep the resistors from shorting to the heatsink, isolate the board from moisture, and hold the heatsinks in place, all while piping heat away from the board. The only hard part will be where to put it when I'm done, but I'm thinking a simple box built around the fans, then screwed down to my floorboard. Might look a bit odd, but it's better than baking in the sun with no A/C. Yay, I get to put on my electrical engineer hat for a while! The guys at the office say I should sell the plans on the internet, that might just be a good idea. If GM sticks this part in most of their recent cars, a lot of people will probably want a solution to this problem.
