Product information

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.
