Aquacomputer Cuplex Kryos NEXT 1851/1700, Copper/Copper (21846)

The Aquacomputer Cuplex Kryos NEXT 1851/1700, Copper/Copper (21846) is a CPU water block for Intel socket 1851 and 1700, with a copper housing and a copper base. A backplate with a rubber cover is included, and the two G1/4 connection threads sit 28 mm apart.

Properties

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

The cuplex kryos NEXT model family

Aquacomputer says the series represents a new milestone in the development of CPU water coolers. Every detail, it says, was analyzed, optimized and tested in order to achieve perfection in the areas of cooling performance, assembly and functionality. In its words the result sets new standards in cooling performance, and an entire model family covers a spectrum of color and equipment variants.

A worldwide unique feature, by Aquacomputer's account, is the base plate of the VARIO models, which can be deformed during operation. Never before has a CPU cooler been able to be adjusted for an optimal fit on the CPU while the PC is running. The models with the VISION module have powerful electronics: 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 with neither; the VARIO version for the same socket is the cuplex kryos NEXT VARIO 1851/1700, nickel/nickel.

Cooler base with microstructure

The cooler base is equipped with an extremely fine microstructure with a structure width of less than 200 µm. Coolant flows through a flat nozzle in the cooler housing onto the center of the microstructure. From there it is discharged in two directions. Depending on the cooler variant, the base is made of copper, nickel-plated copper or .925 silver plated copper. On this one the material combination is copper/copper: housing copper, cooler base copper.

Mounting system

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

For the cooler variants for socket 1851/1700, a backplate with a rubber cover is part of the scope of delivery. It additionally stabilizes the mainboard around the CPU.

What the loop needs

Both connection threads are G1/4, 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

• 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.
