The cuplex kryos NEXT series
Aquacomputer says the cuplex kryos NEXT represents a new milestone in the development of CPU water coolers. By its account, every detail was analyzed, optimized and tested in order to achieve perfection in three areas: cooling performance, assembly and functionality. The result, it says, is not just one CPU cooler that sets new standards in cooling performance but an entire model family, covering a spectrum of color and equipment variants.
The models with the VISION module carry powerful electronics. A high-resolution OLED display, integrated water temperature measurement and a USB interface are just three examples of their range of functions. This block pairs that module with the VARIO base; the same block without the module is the cuplex kryos NEXT VARIO 1851/1700, nickel/nickel (21865).
VARIO: adjustable geometry of the cooler base
The VARIO variants allow the geometry of the cooler base to be changed with four lateral adjustment screws on the sides of the water block. Aquacomputer describes a base plate that can be deformed during operation as a worldwide unique feature of CPU water coolers. Never before, it says, has a CPU cooler been able to be adjusted to an optimal fit to the CPU while the PC is in operation.
The reason is that no two processors are absolutely identical. Each CPU is unique, and minimal height and shape differences in the metal caps (the metallic lids) of today's CPUs have a significant impact on the cooling performance of a water cooler. With previous solutions for changing the cooler geometry, the cooler had to be laboriously dismantled and then reassembled on the CPU, which represented an enormous effort in time. Aquacomputer says the VARIO makes adapting the geometry child's play, done in just a few moments.
The adjustment is done while the PC runs: the temperature of all cores is monitored at full load, and the base is optimally adjusted using the four screws. Temperature changes provide immediate feedback, so the best setting is quickly identified.
How to adjust it
Each water block is pre-adjusted at the factory to a geometry that performs very well with a number of CPUs, and a laser engraving on the screws marks this preset. Adjusting needs the block installed on the CPU and integrated into a functioning water cooling setup. Use extreme caution and do not touch any motherboard components.
Watch CPU temperature or the CPU core temperatures in software. Aquacomputer names aquasuite version 2017 or higher (tab "Quick data view"), HWiNFO, Core Temp, Open Hardware Monitor and AIDA64, and some motherboard manufacturers also provide suitable software. Put the CPU under heavy load, for example with Prime95 or OCCT.
Vary the position of one adjustment screw slightly. If the temperature decreases, keep turning it in the same direction; if it increases, reverse. Repeat for all four screws, and never rotate a screw by more than one revolution from its original position. To reset to the factory setting, screw each one in until the stop, then loosen it by approximately one revolution until the marking on screw and water block align.
VISION: integrated electronics
The VISION variants are equipped with a microprocessor control and an OLED graphic display. The most important features include:
- water temperature measurement integrated in the cooler
- a connection option for a flow sensor, or alternatively an alarm output
- a USB interface to the PC
- an aquabus interface for data exchange with an aquaero 5 or 6
- configurable display pages on the display
- a wide range of hardware data shown on the display via the aquasuite software, e.g. the current processor load
In the acrylic versions of the cuplex kryos NEXT with VISION, an additional RGB LED is integrated for lighting, which can be controlled depending on the temperature or via USB. This block has a nickel plated brass housing and no LED.
Due to the limited space, a maximum of two connection cables can be fed into the cooler. The possible combinations are therefore:
- USB and aquabus
- USB and flow measurement or alarm output
- aquabus and flow measurement or alarm output
Radiator base with micro structure
The cooler base (Aquacomputer also says radiator base or radiator floor) is equipped with an extremely fine microstructure, with a structure width of less than 200 µm. The coolant flows through a flat, slot-shaped nozzle integrated in the cooler housing and hits the center of the microstructure. From there it is discharged in two directions, to both sides of the structure. Depending on the cooler variant, the base is made of copper, nickel-plated copper or .925 sterling silver.
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 block to the mainboard. When installed, the holding system looks very tidy due to the spring cup design and the low overall height.
All bracket variants have a defined stop, a mechanical limit for optimal contact pressure and force distribution. The knurled screws can be fitted by hand, and a hexagon socket drive also allows for easy assembly. The cooler variants for socket 1851/1700 come with a steel back plate with a rubber cover (insulation), which additionally stabilizes the CPU region of the mainboard.
Thermal paste
Every cuplex kryos NEXT comes with 0.5 grams of what Aquacomputer calls excellent thermal paste, packed in a syringe for easy use, and a plastic spatula for application. The paste has a high thermal conductivity. Thanks to its low viscosity it spreads very well between the CPU and the water cooler during assembly. The supplied quantity is sufficient for approx. five assemblies of the cooler.
Color variants
Across the family, the cooler housing is available in different materials and coatings:
- Acetal black: a black, shiny high-performance plastic
- Acrylic glass: a transparent housing with a lighting option
- Copper: a reddish shine
- Nickel-plated brass: a light metallic shine
- Brass, PVD coated: a high-quality multi-layer coating with a dark metallic shine
The material combination of this block is nickel/nickel: a housing of nickel-plated brass and a nickel-plated copper cooler base.
Installation
Remove the old CPU cooler and, if necessary, clean thermal grease residues off the CPU surface with benzine. Put a small drop of the supplied grease, about 4 mm (0.15 inch) across, centrally on the CPU, or spread a thin layer with the plastic spatula.
The water block comes as a mounted cooler, together with the fastening set (screws, springs, etc.) and assembly instructions. Arrange the back plate and the black insulation mat below the processor socket. Slide one plastic washer onto each retention bolt and screw the four bolts through the mounting holes of the motherboard into the back plate. Set the block on the CPU in the orientation the manual shows, then put a spring on 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
The two connection threads are G1/4, so the block takes two fittings from our fittings section. For best cooling performance the coolant must enter through the central fitting; a reversed flow direction significantly decreases cooling performance. For corrosion inhibition, Aquacomputer requires Double Protect Ultra as coolant.
What you need to connect it
No cables are listed in the scope of delivery. For USB, use the internal USB connection cable for VISION (53215). An aquaero 5 or 6, such as the aquaero 6 LT, connects through the aquabus cable for VISION (53214). Flow sensor and alarm cables are among our VISION CPU accessories.
aquasuite software
Activating this product gives you the current version of the aquasuite software, with an upgrade service for at least six (6) months. Once that expires, you may use and reinstall the latest version released during the upgrade period without a time limit. The update service can optionally be extended or renewed at any time for a fee. Installation and activation need an internet connection.
