Though I'm not certain, it seems reasonable to think that the key temperature is the junction temperature, which is much higher than the air temperature. With more efficient cooling, that is, higher conductivity, the delta-temperature can be lower, and as a consequence, the liquid coolant could be at typical outdoor temperatures (or close) thereby reducing the need for air conditioning. I'll add, the heat exchange between the liquid and the external cooling would need to be very efficient as well, otherwise air conditioning would be needed to get the delta-temperature to get the necessary heat flow from coolant to outside world.
