A new performance champion is always worthy of praise and the AquaComputer cuplex kryos XT is no exception. The margin of victory is the smallest in my history of testing blocks, but a win is a win. Add to that a better mounting system than the EK Supreme HF, the all metal construction (yes, there is an all metal version of the Supreme HF, although I would not assume it performs identically to the Supreme HF I’ve tested), and the aggressive styling, and this block is a winner.
Despite the great performance and looks, the block isn’t perfect. The mounting system is just not in the same league as the Swiftech/D-Tek/Koolance mounting systems, the barb spacing is uncomfortably tight, and the lack of universal socket support (out of the box) is disheartening. In my use, the inner o-ring was difficult to tame when assembling the block, which wouldn’t be a big deal except that switching mounting brackets requires full disassembly of the block. As performance of all the flagship blocks seem to coalesce, the little things begin to matter more and more.
One little thing that AquaComputer got right was the inclusion of Prolimatech PK-1, a widely lauded TIM. Inclusion of a good TIM is worth a lot in my book–if the end user was planning to use a good TIM, overall cost of implementation goes down; if the end user was planning to use the included TIM, overall performance is improved a huge amount relative to generic TIM.
Overall, the AquaComputer cuplex kryos XT is a tremendous block. It delivers the best CPU temperatures I’ve ever seen, has great looks, and acceptable restriction. It’s hard to argue with performance; everyone is after the best CPU temperatures and the kryos XT delivers. It has its tradeoffs and peculiarities, but every block does.
