While Dell continues to offer liquid cooling in their Alienware gaming computers, they have discontinued use of the H 2 C technology with the XPS 730X being the last model to utilize it. Liquid cooled Alienware computers are not equipped with TECs and do not require a daughterboard (MCB) for the cooling system.
The last known devices to utilize the ESA specifications were the Dell XPS 730x and Alienware Area-51 ALX computer systems that utilized the ESA specification to control its fans, LEDs, and motorized doors as well as the monitoring of available Water cooling systems such as the Dell XPS 730x's Dell H 2 Ceramic Cooling System.
