I purchased a regular 120 volt 5 inch small fan from Walmart, removed the base and was able to install it on the bottom of the vent opening to push hot air up and then bought another one and did the same thing only installed it on the top vent area to help push the hot air out. I ended up wiring them in unison and installing a manual on and off switch plugged into the 110 socket in that compartment. The on and off switch was accessible from the outside of the vent and when we were parked where it was hot, I then turned on the fans. They were quiet and really moved a lot of air. I don't think I could ever get ice cream to freeze solid, but my ice stayed frozen and it really helped when we were in those hot climates.
