So for now I have added a 15' copper coil into the lower refrigerator compartment of the water cooler I have. The water from the water cooler gets pumped out and passes through the coils in the refrigerator on its way to the radiator for additional cooling. The returning water from the radiator passes through a 10' cooper coil that is placed in the water cooler itself. Unfortunately I can only get 10F difference (in
this thread the thermometer was too close to the radiator) in the temperature (with no additional external heating source such as lights). I have noticed however that there is still some heat I could shed in the bottom refrigerator as the temperature even with coil inside stays at 50F while the temperature in the top water cooler is 65F, 67F with 80F in the room.
av8tor1, I was wondering does it mater which line I'm running through the bottom cooler at this point, to_the_radiator or from_the_radiator? I'm still putting the same load on the system?
Three possible improvements to squeeze more juice out of the system that I see so far are:
1) Obviously I need to insulate the tank.
2) Run both to_the_radiator and from_the_radiator lines through the bottom refrigerator
3) Increase the length of the copper coils placed in the radiator.
Pardon the mess, this is work in progress

I took off the door for now and instead paced that slab of styrofoam. Wasn't ready to drill the door just yet.
