Graphics water block BitsPower Nebula Strix/TUF 4080 ARGB Nickel + Acryl (BP-VG4080AST)

BitsPower Nebula Strix/TUF 4080 ARGB Nickel + Acryl is a full-cover graphics water block engineered for RTX 4080 Strix and TUF style graphics cards. The block combines a nickel-plated copper cold plate with an acrylic top and integrated ARGB lighting to provide direct liquid cooling for the GPU core, surrounding VRAM modules and VRM components. Designed for custom liquid cooling loops, the block improves heat transfer from critical semiconductor areas to reduce operating temperatures and enable quieter system operation and more stable overclocking.

Advantages

The nickel-plated cold plate provides corrosion-resistant thermal contact and effective heat conduction, while the acrylic top allows visual monitoring of coolant flow and internal channels. Integrated ARGB lighting offers adjustable illumination compatible with common motherboard controllers and ARGB hubs. The full-cover design targets all major heat sources on Strix/TUF style 4080 cards, eliminating the need for separate fan-based cooling on the PCB and simplifying integration into a custom loop. Precision-machined channels and port positioning support predictable flow and straightforward installation in multi-component systems.

Suitable for

• Custom liquid cooling loops for RTX 4080 Strix/TUF style graphics cards
• PC builds focused on silent operation and reduced GPU temperatures
• Systems requiring support for moderate to advanced GPU overclocking
• Showcase builds where ARGB lighting and visible coolant routing are desired

Key specifications

• Compatibility: Full-cover design for RTX 4080 Strix/TUF style PCBs
• Primary construction: Nickel-plated copper cold plate with acrylic top
• Cooling coverage: GPU core, adjacent VRAM modules and VRM area
• Lighting: Integrated ARGB illumination compatible with standard 3-pin ARGB headers
• Port layout: G1/4" threaded ports for inlet and outlet connections
• Mounting: Includes mounting hardware and thermal pads for required contact points

How to use

Prepare the graphics card by removing the original air cooler according to the card manufacturer’s service instructions and clean contact surfaces with isopropyl alcohol. Place the provided thermal pads over VRAM and VRM contact areas and apply a thin, even layer of thermal compound to the GPU die. Align the water block on the PCB and secure it using the supplied mounting screws in the recommended sequence to ensure even pressure. Connect the ARGB cable to a compatible header or controller and attach inlet/outlet fittings and tubing to the G1/4" ports. Pressure-test the loop outside the system before powering the PC to check for leaks and confirm proper flow and lighting function.

Recommendations

Use coolant approved for PC water cooling to avoid corrosion or biological growth, and follow regular maintenance intervals for coolant replacement. Verify compatibility with your specific RTX 4080 Strix/TUF variant and consult the manufacturer’s installation guide for torque values and mounting details. When routing tubing, leave slack at connection points to reduce stress on fittings and check ARGB settings in your motherboard or controller software to synchronize lighting effects.
