CPU socket
The components are delivered as a single unit designed to last a minimum of 5 years without service or liquid refilling. The XPS 710 H2C and Dell XPS 720 H2C featured a design where all components were mounted in a single plastic chassis and which only cooled the CPU. This design only matched motherboards with a very specific CPU socket location and was later replaced by a new and more flexible design featuring a separate pump unit which made it much easier to fit a broader range of motherboards with different CPU socket locations. The new design allowed the unit to cool the motherboard chipset as well.
