Aquacomputer Cuplex Kryos NEXT RGBpx AM5/AM4/3000/5000/7000, Acetal / Nickel (21808)

The Aquacomputer Cuplex Kryos NEXT RGBpx AM5/AM4/3000/5000/7000, Acetal / Nickel (21808) is a CPU water block for AMD socket AM5 and AM4, with a white acetal top and a nickel-plated copper base.

Base

Nickel-plated copper, fine micro structure

Ports

2x G1/4, 25.5 mm apart

Size

111 x 75 x 22 mm (not including screws)

Lighting

11 individually addressable RGBpx LEDs

Cooler base and flow

Aquacomputer says the cuplex kryos NEXT represents a new milestone in the development of CPU water coolers, and that the areas of cooling performance, assembly and functionality have been perfected here. Fed by an integrated flat nozzle in the housing, coolant flows into the middle of the extremely fine microstructure (structural width below 200 µm) and out to both sides. Aquacomputer says it thus sets new standards for cooling performance. Here the radiator base is made of nickel-plated copper.

Mounting system

The mounting system is solid stainless steel sheet, 2.5 mm thick, with the nickel-plated spring cups pressed in. Attaching the cooler to the mainboard with knurled screws and springs keeps the holding system visually very tidy due to the low height. The bracket has a defined stop for optimal contact pressure and force distribution.

With the cuplex kryos NEXT for Socket AM4/3000/5000, the heat sink is not positioned in the center of the CPU but rather slightly off it, for the internal structure of the Ryzen CPU series. Aquacomputer gives this offset for the Ryzen 7000, 5000 and 3000 series: that way, it says, optimal heat dissipation can be guaranteed. No additional backplate is required.

The excellent thermal paste in the box comes from Thermal Grizzly: Kryonaut, 0.5 grams packed in a syringe, which can be easily applied with the enclosed plastic spatula. Aquacomputer says the amount is sufficient for approximately five applications.

RGBpx illumination

The 11 LEDs are integrated under the silver aluminum cover. The included cable connects them to an Aqua Computer RGBpx output, and the adjacent connector takes more RGBpx components in a daisy chain.

Compatibility

Aquacomputer lists these products with an RGBpx output:

• D5 NEXT (41118)
• farbwerk 360 (53279)
• farbwerk nano (53280, 53281)
• OCTO (53286)
• QUADRO (53256)

The RGBpx adapter (53285), sold separately, fits common motherboard headers for addressable LEDs.

What the loop needs

The G1/4 ports take two fittings. Coolant comes in through the fitting close to the center and returns through the lateral connector next to the "NEXT" engraving; reversed flow significantly decreases cooling performance. Aquacomputer requires Double Protect Ultra as coolant for corrosion inhibition.

In the box

• 1x mounted cooler
• 1x mounting kit (screws, springs, etc.)
• 1x Thermal Grizzly Kryonaut thermal paste, approx. 0.5 grams in syringe
• 1x plastic spatula
• 1x RGBpx connection cable 50 cm
• 1x assembly instructions

The manual covers mounting, flow direction and RGBpx.
