I did the same experiment as Dixi in A320. With medium weight, idle reverse and some headwind it took 2500-2700 meters to decelerate without touching the brakes.
Having said that, according to Airbus, there's no benefit of keeping the carbon brakes cool (except for short turnaround considerations). Carbon brakes wear does not depend on brake energy absorbed, but primarily on number of applications. Also, they actually wear more at low and moderate temperatures (100-250deg) than at higher temperatures! Only when you exceed ~500degs, the wear increases again due to oxidation.
Have a look at the following video

Brake wear and oxidation is two very different things :
Brake wear is dependant on temperature and number of applications :
The optimum temperature is dependent on which manufacture you have installed (A32x have 3 different) so not just one optimum temperature. No so much you can do to have the brakes at optimum temperature, except using brake fans to control temperature, and use correct flap/reverse/autobrake setting.
But number of applications you as a pilot can do a lot to reduce. Airbus informs that 75 % of brake wear happens during taxi !! Use the 10/30 kts technique.
Oxidation is not wear, but degration of material. The two main causes are repeated high temperatures (> 500 ' C) (thermal oxidation) and runway deicer fluids (chemical oxidation). These two combined accellerate oxidation a lot.
Airbus has quite some imformative documents about the subject.
