Aquacomputer Cuplex Kryos NEXT 1851/1700, Acetal/Copper (21847)

The Aquacomputer Cuplex Kryos NEXT 1851/1700, Acetal/Copper (21847) is a CPU water block for Intel socket 1851 and 1700, with a top part of black acetal and a copper base. Its two G1/4 connection threads sit 28 mm apart, and a steel back plate is part of the scope of delivery.

Properties

• Sockets: Intel 1851, 1700
• Top: Black acetal
• Base: Copper, micro structure under 200 µm
• Ports: 2x G1/4 connection threads, distance between threads 28 mm
• Dimensions: Socket 1700: 94 x 94 x 22 mm (not including screws and back plate)

The cuplex kryos NEXT series

Aquacomputer says this block marks a new milestone in CPU water block development. In its account, every detail was analyzed, optimized and tested to achieve perfection in cooling performance, in the installation procedure and in product features. The result, it says, is not just one water block with outstanding performance but a product series, with various models differing in color and functionality.

The VARIO models were, by Aquacomputer's account, the first CPU water blocks globally to incorporate a real-time adjustable base. Never before was it possible to adjust the geometry of a CPU block to fit the CPU perfectly while the PC is in operation. Models with the VISION module are equipped with modern electronics, and a high resolution OLED display, an integrated water temperature sensor and a USB interface are just three of their features. This article has neither feature: it is the plain block in acetal and copper.

Base part with micro structure

Under the block sits an extremely fine micro structure whose structural width is lower than 200 µm. Coolant is injected centrally through a slot-shaped nozzle, then runs outward to both sides of the structure. Depending on the model, the base itself is manufactured from copper, nickel plated copper or .925 silver plated copper. Here the material combination is acetal/copper: top part black acetal, base copper.

Retention system

The retention system consists of two stainless steel plates, 2.5 mm thick and fitted with nickel plated spring cups. Springs and knurled screws hold the water block on the motherboard, and when installed the hardware has a very clean look. All versions of the retention system have a mechanical stop, which gives optimum clamping force and an even force distribution. You can turn the knurled screws by hand, and a hexagon socket wrench can additionally be used for easy installation.

The versions for socket 1851/1700 all include a steel back plate with rubber insulation, there to stabilize the CPU region of the motherboard.

What the loop needs

According to Aquacomputer's technical details, both connection threads are G1/4, so the block takes two fittings. For best cooling performance, the coolant must enter through the central fitting, because reversed flow direction significantly decreases cooling performance. For corrosion inhibition, Aquacomputer requires Double Protect Ultra as coolant.

Notes

• Put the water cooling system into operation first with no other PC components connected to the mains supply, and check the block and the fittings for leaks.
• A component that has been in contact with coolant must be completely dry again before it goes into operation.
