Hutch,
Even on a new install of an aftermarket A/C system they recommend a condenser fan. This can be wired to come on when the compressor cycles on and go off when the compressor is off. This should help maintain adequate heat transfer even when the vehicle isn't moving. They also strongly recommend maintaining the clutch driven original style engine fan and shroud. Just keep in mind that even properly operating systems have a temperature increase when the outside air temp increase or the vehicle is not in motion. Good luck and stay cool.
