Water Cooling Block Barrow LRC2.0 for GIGABYTE 3080/3090 Extreme RGB Acryl

Barrow LRC2.0 water cooling block for GIGABYTE 3080/3090 Extreme RGB Acryl is a full-coverage GPU block engineered to deliver direct liquid cooling to the GPU die and nearby components. The block is shaped to match the PCB layout of compatible GIGABYTE Extreme RGB Acryl models and provides efficient heat transfer from the graphics processor and surrounding VRAM/VRM areas to the coolant loop. Designed for integration into custom water-cooling systems, this block helps lower operating temperatures and reduce fan noise during sustained high loads.

Advantages

The block uses a precision-machined cold plate that ensures close contact with the GPU and adjacent components, enabling consistent thermal performance. A transparent acrylic top with RGB-compatible channels maintains the aesthetic of GIGABYTE's Extreme series while allowing coolant visibility. The design supports single-screw or multi-point mounting (as required by compatible boards) and includes a thermal interface solution matched to the card layout to streamline installation and optimize heat transfer.

Suitable for

• Custom water-cooling loops for GIGABYTE 3080 and 3090 Extreme RGB Acryl graphics cards
• Gaming rigs aiming to reduce GPU temperatures and acoustic noise
• Workstations used for rendering, simulation, or compute-intensive tasks requiring sustained cooling
• Users who want visual integration with RGB-capable GIGABYTE systems

Key specifications

• Cooling coverage: GPU die, adjacent VRAM and VRM areas
• Top material: transparent acrylic (Acryl) with RGB compatibility
• Cold plate: precision-machined metal for direct thermal conduction
• Interface: pre-applied or included thermal pads/paste for matched component contact
• Mounting: hardware set designed for the specified GIGABYTE Extreme PCB layout
• Inlet/outlet fittings: standard G1/4" threaded ports for loop connection

How to use

Install the Barrow LRC2.0 block by first preparing the graphics card: remove the factory cooler according to the card manufacturer's guidance and clean the GPU die and surrounding component surfaces. Position the water block onto the PCB so that the cold plate aligns with the GPU and thermal pads contact VRAM/VRM. Secure the block using the supplied mounting hardware, tightening screws in a cross pattern to ensure even pressure. Connect the block to your custom loop using G1/4" fittings and perform a leak test before powering the system. Monitor temperatures after installation to verify improved thermal behaviour.

Recommendations

Use coolant compatible with acrylic tops and avoid aggressive chemicals that can degrade seals or the acrylic surface. Ensure the loop includes a reliable pump and a properly sized radiator to handle the thermal load of high-performance GPUs. Regularly inspect fittings and coolant condition, and re-torque mounting screws after initial thermal cycles if necessary.
