From the reliability standpoint Intel offers very robust motor technology. Moreover, every unit is leak and seal tested.
As you may have noticed from the picture above, the tubing is firm. The reason for this material choice is the fact that PCV based or rubber based tubes cause the majority of the fluid loss in the system. If you decide to go with a hard tube approach and implement it properly, you may not need a separate reservoir unit, because the fluid loss throughout the entire service time will be not so great and you do not need an extra reservoir for reserve purposes.
After the system is assembled, they fill it with liquid through the charge port. The liquid inside is 35% propylene glycol aqueous solution. After that the charge port is sealed for life (white top). Then the unit undergoes all the necessary tests to ensure that there are no leaks or pressure losses.
According to Intel, this cooling solution is much more efficient than many others out there thanks to the construction peculiarities. Namely, the fluid is entering the module through the center of the pump. It is impinging into it, and it allows high heat transfer coefficient than in case of parallel contact. Besides, we have already mentioned that the pump is kind of wrapped around the cold-plate, and by doing that we get a larger radius of the cooling module, which also affects the efficiency positively.
Intel advanced liquid cooling solution can fit into ATX as well BTX infrastructure. Here it is:
On the show floor we could see a gaming system equipped with the new Intel advanced liquid cooling solution that was running at an unprecedented speed of 5GHz in Quake 4 game. Here is a screenshot:
