Keeping the server room cool is just using an air conditioner which is cooled by a radiator with a fan, and then using that cooled air to cool another radiator with a fan. Every step is a loss of efficiency.
The main advantage of water loops is that you get to use a different form factor for the radiator and fan by moving it away from the source of heat and aren’t limited by the case dimensions.


The PS3 including a BD drive certainly played a part though.
MS tried to push HD-DVD but required a separate device to use it on 360.
It feels like that was the generation of poor console decisions.
