If you want to continue the project

1) To clean out the radiator I first get some brake cleaner and spray a whole can thru the evap and then condensor. Helps remove some gunk and some of rust corrosion off. I would remove all the electrical stuff and high pressure wash the rads/heat exchangers at carwash or with garden hose. If you dont want to remove the electronic I would wrap it in a few plastic bags and wrap it with duct tape several times. My dad sprays the AC unit at his place dozens of times and its works.

2)Remove the stock fan and build a shroud for some 120mm fans at low speed will reduce noise and EDIT (increase temps)
3) instead of running inline put a rad in the container and submerge a pump. The rad makes the setup less efficient and the inline pumps helps produce some heat directly into the loop. might reduce condensation.
4) Having a seperate loop in the container you don't have to worry about corrosion as much. Still drop a zerez or water wetter and anti-freeze in the res.
