I do have, and can't give up, the A/C radiator. Removing it would help cooling, but really, the only times the car gets excessively hot is, yep, in traffic jams in Seoul afternoons. I took the car out last Sunday because I decided at the last minute to bask in A/C rather than sweat it out on the bike and all the radiated heat from the road, the sun, and millions of cars not moving. Should have chosen option B...but in doing so, my car becomes a vampire. There was an 8 month stretch where the car literally never saw the sun - it ran at night, and was parked before sunrise...
I might consider running both options (not at once). Installing electrics during the winter - I have problems *warming* the car during the brutal Seoul winters and could do without a fan making things worse (I have a Trust twincore radiator, N1 pump, and Nismo thermostat fitted). Removing the viscous fan takes five minutes, and an electric fan setup, if the brackets are designed for quick removal, can also be done rather simply.
