Water block radiator BitsPower NEBULA V2 TUF Gaming RTX 5090, ARGB, acrylic, black

BitsPower NEBULA V2 TUF Gaming RTX 5090 is a dedicated water block radiator engineered for direct liquid cooling of RTX 5090 graphics cards. Constructed with an acrylic top in a black finish and integrated ARGB illumination, the unit provides a contact surface for coolant flow over the GPU and related hot components, enabling efficient heat transfer within custom water-cooling loops for gaming and high-performance desktop systems.

Advantages

The acrylic top offers a clear, durable surface that complements modern PC builds while the black finish matches TUF-themed components. Integrated ARGB lighting provides customizable illumination that can be synchronized with compatible controllers. The block is shaped to align with RTX 5090 reference layouts, supporting direct cooling of the GPU core and associated VRAM/VRM areas. Designed for use in closed-loop custom liquid systems, the block promotes lower operating temperatures and stable performance under sustained loads.

Suitable for

• Custom water-cooling loops in gaming PCs
• High-performance workstations requiring GPU thermal management
• Enthusiast builds focused on aesthetics with ARGB lighting
• Overclocked RTX 5090 graphics cards needing enhanced cooling

Key specifications

• Compatibility: Designed for RTX 5090 graphics card PCB layout
• Material (top): Acrylic
• Finish: Black
• Lighting: ARGB illumination compatible with common controllers
• Cooling type: Full-cover water block for GPU core and surrounding components
• Mounting: Hardware included for secure attachment to compatible GPU

How to use

Install the water block by first removing the original GPU cooler following manufacturer guidelines, then position the block onto the GPU so that thermal interfaces align with the GPU core and memory modules. Apply appropriate thermal pads and paste where required, secure the block using the supplied mounting hardware, and connect the block to your custom cooling loop using compatible fittings and tubing. Connect the ARGB cable to a supported header or controller and verify coolant flow and leak-free connections before powering the system.

Recommendations

Use quality non-conductive coolant and compatible fittings; perform a pressure test or leak check outside the system before initial use. Periodically inspect seals and coolant condition, and follow standard ESD precautions and GPU handling procedures during installation and maintenance.
