2. Safety Information

Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions may result in product damage, system damage, or personal injury.

• Professional Installation Recommended: Installation of liquid cooling components requires experience with PC hardware and liquid cooling systems. If you are unsure, seek professional assistance.
• Power Disconnection: Always disconnect power from your computer before performing any installation or maintenance.
• Electrostatic Discharge (ESD): Take precautions against ESD by using an anti-static wrist strap or by regularly touching a grounded metal object.
• Leak Testing: Thoroughly leak test your liquid cooling loop for at least 24 hours before powering on your system. Use a dedicated leak tester or run the pump with the system powered off.
• Coolant Compatibility: Use only approved liquid cooling coolants. Mixing incompatible coolants can lead to corrosion and system damage.
• Component Compatibility: Ensure this water block is compatible with your specific graphics card model (ASUS ROG Strix GeForce RTX 20 series).
• Avoid Over-tightening: Do not over-tighten screws during installation, as this can damage the water block or graphics card PCB.

3. Setup and Installation

Follow these steps carefully to install the Bitspower Lotan VGA Water Block onto your ASUS ROG Strix GeForce RTX 20 series graphics card.

3.1. Preparation

1. Gather all necessary tools: Phillips head screwdriver, thermal paste, thermal pads, and a clean, static-free workspace.
2. Refer to your graphics card manufacturer's instructions for safe disassembly of the stock cooler.
3. Carefully remove the stock cooler from your graphics card.
4. Clean any residual thermal paste from the GPU die and thermal pads from other components using isopropyl alcohol and a lint-free cloth.

3.2. Water Block Mounting

1. Apply thermal pads to the designated areas on the water block or graphics card, as indicated in the included diagram (if applicable). Ensure proper contact with memory modules and VRMs.
2. Apply a small amount of high-quality thermal paste to the center of the GPU die.
3. Carefully align the water block with the mounting holes on the graphics card PCB.
4. Gently place the water block onto the graphics card, ensuring the GPU die makes contact with the cold plate.
5. Secure the water block using the provided screws and standoffs. Tighten screws in a diagonal pattern, gradually increasing pressure until snug. Do not over-tighten.

3.3. Integrating into Liquid Cooling Loop

1. Install appropriate fittings (not included) into the G1/4" ports on the water block.
2. Connect the water block to your liquid cooling loop using compatible tubing. Ensure all connections are secure.
3. Fill your liquid cooling system with an approved coolant.
4. Perform a thorough leak test for at least 24 hours before powering on your computer. Monitor for any drips or moisture around fittings and the water block.
5. If your water block features RGB lighting, connect the RGB cable to a compatible motherboard header or RGB controller.

4. Operating Instructions

Once properly installed and leak-tested, the Bitspower Lotan VGA Water Block operates as a passive cooling component within your liquid cooling loop. Its primary function is to transfer heat from the GPU and other critical components into the circulating coolant.

• System Power-On: After successful leak testing, power on your computer.
• Temperature Monitoring: Use monitoring software (e.g., HWMonitor, GPU-Z) to observe GPU temperatures during idle and load conditions. Ensure temperatures are within safe operating limits.
• Pump Operation: Ensure your liquid cooling pump is operating correctly and maintaining adequate flow rate.
• RGB Control: If connected, manage the RGB lighting effects through your motherboard's software or a dedicated RGB controller.

5. Maintenance

Regular maintenance is crucial to ensure the longevity and optimal performance of your liquid cooling system and the Bitspower Lotan VGA Water Block.

• Coolant Replacement: Replace the coolant in your loop every 6-12 months, or as recommended by your coolant manufacturer. This prevents buildup and maintains cooling efficiency.
• System Inspection: Periodically inspect tubing, fittings, and the water block for any signs of leaks, corrosion, or coolant discoloration.
• Dust Removal: Keep your computer case clean and free of dust to ensure proper airflow through radiators, which impacts overall loop performance.
• Water Block Cleaning: If performance degrades significantly, or if you observe buildup within the water block, it may require disassembly and cleaning. This should only be performed by experienced users. Use distilled water and a soft brush for cleaning, avoiding abrasive materials.
