Ever think about venting some of the underhood air through the heater box into the car through the cabin air filter? Might help a bit during the winter to keep warm without electrical load from the fan. I know you can already just turn your heater controls to freeflow to get some warm air through the heater core, but if you use part of the underhood air, it would be somewhat pressurized, no?
