Waterblok en backplate voor GPU's BitsPower BP-VG3090EVXC3 — acryl, koper, chroom-nikkelstaal, 125,4 × 263,7 × 25 mm

BitsPower BP-VG3090EVXC3 is a single-piece GPU water block with matching backplate designed for liquid cooling of EVGA GeForce RTX 3090 XC3 series graphics cards. The assembly comprises an acrylic top, a copper cold plate and a chrome-nickel steel backplate, and measures 125.4 × 263.7 × 25 mm. It covers the full length of the card to provide direct contact with the GPU and key power delivery components, and integrates with standard custom PC cooling loops to reduce GPU temperatures and acoustic output.

Advantages

The combination of a copper cold plate and an acrylic top provides efficient heat transfer from the GPU die and surrounding VRM area while allowing visual access to the coolant and internal channels. The chrome-nickel steel backplate adds structural support and helps distribute heat away from the PCB. The single-piece design simplifies installation compared with multi-part block assemblies and the dimensions ensure full-length coverage for compatible EVGA GeForce RTX 3090 XC3 boards.

Suitable for

• Custom liquid-cooled desktop PCs using EVGA GeForce RTX 3090 XC3 series graphics cards
• Enthusiast builds prioritizing lower GPU temperatures and quieter operation
• Systems where full-length water block coverage and a matching backplate are required

Key specifications

• Top material: acrylic
• Cold plate material: copper
• Backplate material: chrome-nickel steel
• Form factor: single-piece GPU water block with backplate
• External dimensions: 125.4 × 263.7 × 25 mm

How to use

Prepare the graphics card by removing the original air cooler and cleaning thermal interfaces from the GPU die and nearby components. Position the BitsPower water block onto the card so the copper cold plate contacts the GPU and VRM areas, align mounting points, and secure the block following the manufacturer’s torque recommendations. Connect inlet and outlet ports to the loop using appropriate fittings and tubing. Fill the cooling loop with a compatible coolant, perform leak testing, and verify flow before powering the system.

Recommendations

Use corrosion-inhibited or manufacturer-recommended coolant to protect copper and steel surfaces, and choose fittings compatible with the block’s port size. Maintain regular loop inspections for leaks and coolant condition, and follow EVGA guidance regarding mounting pressure and electrical safety when replacing the stock cooler.
