The R12 condenser just is not efficient enough at shedding the latent heat from the R134a refrigerant. An electric fan would help and should be considered a must. problem is, there is not enough space to fit a fan between the condenser and the hood latch support structure.
In my experience, the POA update kit is junk. You will feel it (air temp) every time the compressor cycles on/off which will be often.
Good luck.

Old Air Products told me the condenser I got is the same one they sell with their aftermarket AC kits made for 134a. It seems to work above 90 degrees. Maybe it would work better with an electric fan.
