Pete3834, I'm thinking the Trucool mounted in front of your Maggie HX is adding extra heat to your HX. I'm running a Maggie 2300 front nose drive and didn't run the Maggie HX. Instead I installed a Frozen Boost air to water heat exchanger 20x7x2 (Air to Water Radiator) and mounted it down in the lower grille between the fog lights. With the small Maggie reservoir, my temps are only 10* above ambient normally. Under boost temps rise but quickly recover back to normal. My Trucool 40k is mounted in front of the AC condenser as well.
