There is an AFM quick turnaround table - unfortunately I do not have it available. As Rainboe states, brake cooling is rarely a problem due to the lengthy time taken on a normal turnaround. If a quick turnaround is to be planned, then use sensible braking on landing, such as full reverse and manual brakes applied below 100 knots. That will keep the brakes cool, even landing at max. landing weight and high(40's degrees C) ambient temps.
