Cooling Block Barrow LRC 2.0 for MSI RTX 4090 Suprim/Trio RGB — Black Acrylic

Barrow LRC 2.0 cooling block for MSI RTX 4090 Suprim/Trio RGB in black acrylic delivers direct liquid contact to the GPU die and surrounding components. Designed specifically for MSI RTX 4090 Suprim and Trio RGB variants, the block replaces the stock air cooler to provide targeted liquid cooling for the GPU, VRAM and VRM areas. The black acrylic top offers a clean visual appearance while internal coldplate geometry and channeling optimize coolant flow for improved heat transfer and lower operating temperatures.

Advantages

The cooling block reduces GPU temperatures by enabling direct liquid cooling of the GPU core, memory modules and power delivery components, which supports lower sustained temperatures and quieter system operation compared with air cooling. The black acrylic top provides durable coverage and a neutral aesthetic that integrates with RGB-equipped MSI Suprim and Trio cards. Precision machining and a dedicated coldplate layout ensure uniform contact and efficient coolant routing, contributing to stable thermal performance under long gaming or compute sessions.

Suitable for

• Custom water-cooled PC builds using MSI RTX 4090 Suprim or Trio RGB cards
• High-performance gaming rigs seeking lower GPU temperatures and reduced fan noise
• Workstations and rendering systems that require sustained GPU boost clocks
• Silent or showcase systems where aesthetic integration with black acrylic is desired

Key specifications

• Compatibility: MSI RTX 4090 Suprim and Trio RGB graphics card variants
• Material: black acrylic top with machined metal coldplate (copper or nickel-plated copper as per manufacturer construction)
• Cooling method: full-cover water block delivering coolant to GPU, memory and VRM areas
• Mounting: dedicated mounting holes and hardware for direct replacement of the stock cooler on compatible cards
• Fluid ports: G1/4" threaded fittings for standard custom loop integration
• Finish: polished coldplate contact surface for optimal thermal transfer

How to use

Prior to installation, ensure the PC is powered off and disconnected from mains. Remove the graphics card from the system and follow the manufacturer instructions to remove the stock cooler and clean thermal interfaces using isopropyl alcohol. Position the Barrow LRC 2.0 block onto the GPU so the coldplate makes full contact with the GPU die, VRAM and VRM contact points, and secure it with the supplied mounting hardware. Apply appropriate thermal paste on the GPU die and thermal pads where required for memory and power components. Connect the block to the custom loop using G1/4" fittings and verify leak-free connections. Reinstall the card and fill, bleed and test the loop according to standard custom loop procedures before regular operation.

Recommendations

Use high-quality thermal paste and the correct thickness thermal pads as specified by the block manufacturer. Perform a leak test at low pump speed for several hours before powering the rest of the system. Maintain coolant quality and periodically inspect fittings, tubing and block seams for residue or discoloration to ensure long-term performance and reliability.
