First of all, in answering Milt's question on the 'blow-out' plugs, I'm guessing you meant the fuse plugs installed on the wheel rims. Fuse plugs prevent excessive tire pressure built up after excessive braking and during RTOs and as such have nothing to do with the temperature of the brake pack.
Second, aircraft with turnaround times of 30 mins or less would usually have brake-cooling fans installed. Brake-cooling fans are customer-specific items as such you won't find them on aircraft flying long-haul routes.
