Full-coverage block for AORUS Master and Xtreme

The Bykski N-GV3090AORUS-X is a full-coverage water block and matching backplate built for Gigabyte AORUS GeForce RTX 3080 and 3090 Master models plus the Xtreme Waterforce variants. It cools the GPU core, memory and VRM directly from a single nickel-plated copper and acrylic unit. The package includes installation hardware and thermal paste for a complete DIY conversion.

Fits custom loops with parallel or serial flow

The block uses a high-flow internal design that supports both parallel and serial plumbing configurations. Multiple blocks can be run in series, though an extra bridge may be required depending on the loop layout. A black anodized aluminium backplate covers the rear without contacting coolant. Integrated 5 V addressable RGB lighting connects to a standard motherboard header.

Sustained loads stay cooler than air cooling

Direct contact across the core, memory and VRM removes heat continuously rather than in bursts, letting the card hold higher clocks for longer sessions. Lower operating temperatures also reduce thermal cycling stress on solder joints and components. Builders using reference or non-AORUS models will need a different block, as this unit only fits the listed Gigabyte SKUs.

Questions about this item

What is the thermal limit of the nickel-plated copper block under sustained load?

The block directly cools the GPU core, memory, and VRM to lower temperatures for higher overclocks and longer card lifespan.

How much heat does the aluminium backplate add to the loop during all-day operation?

The black anodised aluminium backplate does not contact coolant, so it adds no heat to the water circuit.

Which AORUS cards must I already own for this N-GV3090AORUS-X block to fit?

It fits only the AORUS RTX 3080 Master 10G, RTX 3080 Xtreme Waterforce 10G, RTX 3080 Ti Master 10G, RTX 3080 Ti Xtreme Waterforce 12G, RTX 3090 Master 24G, and RTX 3090 Xtreme Waterforce WB 12G.
