Aquacomputer Cuplex Kryos NEXT 1851/1700, Nickel/Nickel (21845)

The Aquacomputer Cuplex Kryos NEXT 1851/1700, Nickel/Nickel (21845) is a CPU water block for Intel socket 1851 and 1700, with a nickel-plated brass housing and a nickel-plated copper cooler base. Its two G1/4 connection threads sit 28 mm apart, and a backplate with a rubber cover is included.

Properties

• Sockets: Intel 1851, 1700
• Top: Nickel-plated brass housing
• Base: Nickel-plated copper, microstructure under 200 µm
• Ports: 2x G1/4 connection thread, 28 mm distance between threads
• Dimensions: Base 1700: 94 x 94 x 22 mm (screws and backplate not included)

An entire model family

Aquacomputer says the cuplex kryos NEXT represents a new milestone in the development of CPU water coolers. By its account, every detail has been analyzed, optimized and tested in order to achieve perfection in the areas of cooling performance, assembly and functionality. The result, in its words, is not just a CPU cooler that sets new standards in cooling performance. An entire model family covers a spectrum of color and equipment variants.

Aquacomputer calls one feature of the VARIO models worldwide unique among CPU water coolers: a base plate that can be deformed during operation. Never before has a CPU cooler been able to be adjusted to an optimal fit on the CPU while it runs. The models with the VISION module carry powerful electronics, and a high-resolution OLED display, integrated water temperature measurement and a USB interface are just three examples from their range of functions. This block is the version without either.

Cooler base with microstructure

The cooler base is equipped with an extremely fine microstructure, with a structure width of less than 200 µm. A flat nozzle integrated in the cooler housing guides the coolant onto the center of the microstructure. From there it flows on and is discharged in two directions. Copper, nickel-plated copper or .925 silver plated copper are what the base is made of, depending on the cooler variant. This one is the material combination nickel/nickel, with a nickel-plated brass housing and a nickel-plated copper cooler base.

Mounting system

The mounting system consists of solid stainless steel sheets with a material thickness of 2.5 mm, and nickel-plated spring cups are pressed into them. Knurled screws and springs attach the cooler to the mainboard. Due to the spring cup design and the low overall height, the holding system looks very tidy when installed. All bracket variants have a defined stop, for optimal contact pressure and force distribution. The knurled screws can be fitted by hand, while an Allen key also allows easy installation.

For the socket 1700 cooler variants, the scope of delivery includes a backplate with a rubber cover, which additionally stabilizes the mainboard.

What the loop needs

The technical data list G1/4 for the connection thread, so the block takes two fittings. 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

• 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.
