Water block Aqua-Computer 21713 Kryos Next Vision – Acetal and Copper, AM4, black/silver

Aqua-Computer 21713 Kryos Next Vision is a CPU water block for AM4 sockets made from acetal and copper, finished in black and silver. Designed for custom liquid-cooling loops, this Kryos Next Vision model combines a micro-structured copper base with a precisely engineered coolant inlet to ensure efficient heat transfer from modern AMD processors. The VISION variant integrates electronics including a high-resolution OLED display and an integrated water temperature sensor, enabling real-time monitoring of cooling performance without external probes.

Advantages

The Kryos Next Vision features a very fine microstructure in the base to maximize surface contact with the coolant and improve thermal conductivity. Its retention system uses thick stainless steel plates with nickel-plated spring cups and knurled screws for secure, evenly distributed mounting on AM4 motherboards. The product ships with a 0.5 g syringe of high-performance thermal compound (Thermal Grizzly Kryonaut) and a plastic spatula to achieve thin, even application. Integrated electronics on the VISION model provide a built-in water temperature sensor, USB interface and customizable OLED output for direct display of operating data.

Suitable for

• Custom liquid-cooled desktop systems with AM4 CPUs
• Users who want integrated temperature readout and display on the block
• High-performance or overclocked AMD Ryzen systems requiring efficient heat extraction
• Builders preferring a robust retention system and precise mounting

When it may not be suitable

This water block requires a custom liquid cooling loop and is not compatible with closed-loop (AIO) coolers or air-cooling solutions. Systems using non-AM4 sockets will require a different mounting variant. The integrated VISION electronics have limited cable entry space, so only two cables can be routed into the block simultaneously; this may restrict certain multi-sensor or multi-interface setups.

Key specifications

• Compatible socket: AM4
• Main materials: acetal housing and copper base (nickel plating depending on variant)
• Finish: black and silver
• Base microstructure width: below 200 µm
• Retention: 2.5 mm stainless steel plates with nickel-plated spring cups and knurled screws
• Integrated electronics (VISION): OLED display, water temperature sensor, USB interface, aquabus connector, flow sensor/alarm connector
• Included thermal compound: 0.5 g syringe of Thermal Grizzly Kryonaut with spatula

How to use

Mount the water block to an AM4 motherboard using the supplied retention system and ensure even screw torque using the knurled screws or a hex key. Apply the included thermal compound sparingly and spread thinly between the CPU heat spreader and the block base for optimal contact. Connect the water-cooling loop, confirm correct flow direction and leak-test the system before full operation. If using the VISION model, connect the desired combination of two cables (USB, aquabus, or flow/alarm) and configure display options via the compatible software or the block's OLED interface.

What to consider before purchase

• Requires a custom liquid cooling loop; not suitable for closed-loop AIO or air coolers
• Compatibility limited to AM4 socket for this specific model
• VISION electronics allow a maximum of two internal cable connections simultaneously
• Check available clearance on the motherboard and surrounding components for retention system

Recommendations

For best thermal performance, pair the Kryos Next Vision with a well-configured pump and radiator setup, maintain adequate coolant flow, and use the supplied high-performance thermal compound. When using integrated electronics, route only the necessary cables and configure the OLED display or aquasuite settings to show water temperature and relevant system data.
