## Summary description

The EK Water Blocks 3831109836422 is a high-performance water block made from acetal and copper. It features a sleek black and nickel finish, measuring 21 mm in width, 314 mm in depth, and 155 mm in height. This compact design ensures efficient cooling for computer systems, making it an ideal choice for custom cooling setups.

## Long description

The EK Water Blocks 3831109836422 Acetal Copper Black 21mm x 314mm x 155mm is a second-generation EK-Quantum Vector GPU water block engineered for EVGA FTW3 RTX 3070 graphics cards using NVIDIA Ampere architecture. The block combines a nickel-plated electrolytic copper base with a CNC-machined POM acetal top and Acetal terminals to actively cool the GPU core, VRAM, power stages and VRM chokes. Its compact footprint (21 mm × 314 mm × 155 mm) and optimized internal geometry ensure efficient coolant flow and thermal transfer for custom liquid-cooling loops.
Advantages
This water block uses an Open Split-Flow cooling engine design that provides low hydraulic flow restriction and stable performance even with lower-speed pumps. The internal jet plate and fin geometry reduce hydrodynamic instabilities and vortexing, while the fin array includes 28 microfins with 0.6 mm-wide microchannels to balance high cooling efficiency and manageable flow resistance. Nickel-plated copper for the cold plate ensures effective heat transfer, and EPDM O-rings deliver reliable watertight sealing. Built-in D-RGB lighting with eight individually addressable LEDs enables synchronization with major motherboard RGB systems.
Suitable for
Custom liquid-cooled PC builds using EVGA FTW3 RTX 3070 graphics cards
Enthusiast GPU cooling where low flow restriction is desired
Systems requiring active cooling of GPU core, VRAM and VRM power stages
Key specifications
Material: nickel-plated electrolytic copper base and POM acetal top with Acetal terminals
Dimensions: 21 mm (width) × 314 mm (depth) × 155 mm (height)
Cooling engine: Open Split-Flow design with optimized jet plate and fin geometry
Microfin array: 28 microfins with ~0.6 mm microchannels
Sealing: EPDM O-rings
Illumination: 8 individually addressable D-RGB LEDs, 3-pin D-RGB connector (+5V alignment)
Included accessories: mounting mechanism with pre-installed brass standoffs, mounting screws, nuts and washers, 2x nickel-plated brass G1/4" plugs, multi Allen key set, thermal pads, and 1 g thermal grease
How to use
Install the water block onto a compatible EVGA FTW3 RTX 3070 graphics card following the supplied mounting mechanism and pre-installed brass standoffs. Apply the provided thermal pads and the supplied 1 g thermal grease to the GPU contact surfaces as instructed by the manufacturer. Connect the D-RGB 3-pin connector to the addressable header on the motherboard, aligning the arrow on the connector with the +5V marking. Tighten mounting screws evenly to ensure flat contact between the block base and the GPU package, and integrate the block into the loop using standard G1/4" fittings or the included plugs if required.
Usage recommendations
Use coolant compatible with copper and acetal components and follow regular maintenance schedules for liquid-cooling loops. For improved stabilization and passive cooling of the PCB and VRM area, consider adding a retention backplate recommended for 3070 models. Verify pump flow and loop configuration to take advantage of the block’s low hydraulic restriction characteristics.
