you are not taking into consideration that a clean evaporator will cool the cabin better...therefore, it will absorb more heat... the evaporator temp will be higher, the freeze switch will not activate, due to the higher amount of heat intake of the evaporator... that heat will cause more stress on the compressor and condenser.

if the condenser is not clean, straight, and ready for the excess heat... the lifespan of the compressor will not be long.
running the electric fan will assist with heat removal, but CAPACITY and SURFACE area are needed to reject it all.
