The cuplex kryos NEXT series

Aquacomputer says the series marks a new milestone in CPU water block development. It says every detail has been analyzed, optimized and tested to achieve perfection in three areas: cooling performance, installation procedure and product features. In its words, the result is a product series rather than just one CPU water block with outstanding performance, with various models differing in color and functionality.

The VARIO models, by Aquacomputer's account, are the first CPU water blocks globally to incorporate a base that is adjustable in real time. Never before, it says, has it been possible to adjust a CPU block's geometry to perfectly fit the CPU while the PC is in operation. Models with the VISION module include modern electronics, and a high resolution OLED display, an integrated water temperature sensor and a USB interface are just three of those features. This block is the version without either; the VARIO version for the same socket is the cuplex kryos NEXT VARIO 1851/1700, nickel/nickel.

Base part with micro structure

The base part has an extremely fine micro structure, with a structural width lower than 200 µm. The coolant is injected centrally through a slot-shaped nozzle, and from there it runs to both sides of the structure. Depending on model, the base itself is manufactured from copper, nickel plated copper or .925 sterling silver. The material combination of this one is acetal/nickel: the top part is black acetal and the base is nickel plated copper.

Retention system

The retention system consists of stainless steel plates, 2.5 mm thick and equipped with nickel plated spring cups. Springs and knurled screws secure the block on the motherboard, which gives a very clean look when installed. A mechanical stop is a feature of every retention system version, for optimum clamping force and even force distribution. You can turn the knurled screws by hand, and a hexagon socket wrench can additionally be used for easy installation.

A steel back plate with rubber insulation is part of the scope of delivery of all water block versions for socket 1851/1700. Its job is to stabilize the CPU region of the motherboard.

Thermal compound

For optimum performance, Aquacomputer ships every cuplex kryos NEXT with what it calls outstanding, premium grade thermal compound. The syringe holds 0.5 grams and is complete with a plastic spatula. The compound has a high thermal conductivity, and due to its low viscosity it spreads out thin and evenly between CPU and water block. The amount is sufficient for approximately five applications.

Color variants

Across the series, the top part of the water block is available in various materials and coatings:

• Acetal black, a shiny black high-tech plastic
• Acrylic glass, a transparent body suitable for illumination
• Copper, with a reddish gloss
• Nickel plated brass, with a bright metallic gloss
• PVD plated brass, a high quality multi layer coating with a dark metallic gloss

Installation

Take off the old CPU cooler and, if necessary, remove thermal grease residues from the CPU surface with benzine. Place a small drop of the supplied grease, about 4 mm across, in the center of the CPU, or spread a thin layer with the plastic spatula.

The back plate and the black insulation mat go below the processor socket. Slide a plastic washer onto each retention bolt, then screw the four bolts through the mounting holes of the motherboard into the back plate. Set the block onto the CPU in the orientation the manual shows, slide one spring onto each bolt and secure it with a knurled head screw. Fasten the four screws alternately, a fraction of a revolution at a time, until all are fully fastened.

What the loop needs

Both connection threads are G1/4, so the block takes two fittings from our fittings section. For best cooling performance the coolant must be supplied through the central fitting, since reversed flow significantly decreases cooling performance. For corrosion inhibition, Aquacomputer requires Double Protect Ultra as coolant.

Notes

• Fill and run the water cooling system 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.
