Alphacool Eiswolf 2 AIO GPU Cooler & Backplate for RTX 4090 Founders Edition

1. Introduction

The Alphacool Eiswolf 2 is a full-cover All-In-One (AIO) liquid cooling solution specifically designed for the NVIDIA GeForce RTX 4090 Founders Edition graphics card. This unit integrates an Alphacool GPX Eisblock Aurora GPX water cooler, a pump unit, and a 360mm NexXxoS ST30 full copper radiator. It provides comprehensive cooling for the GPU, graphics memory, voltage converters, and other critical components requiring active thermal management.

The integrated pump unit houses the DC-LT 2 pump, an improved and quieter version of the DC-LT Low Noise Ceramic Pump, ensuring efficient coolant circulation with minimal acoustic output. The full copper radiator from the NexXxoS series offers superior heat dissipation compared to aluminum alternatives, contributing to optimal cooling performance.

2. Safety Information

• Read Instructions: Carefully read and understand all instructions before installation and operation.
• Professional Installation Recommended: Installation of liquid cooling components requires technical proficiency. If unsure, seek professional assistance.
• Power Disconnection: Always disconnect power from your computer before installing, removing, or performing maintenance on any components.
• Leak Testing: Thoroughly leak test the system for at least 24 hours before powering on your computer. Use a dedicated leak tester or run the pump with the system powered off.
• Coolant Compatibility: Use only approved coolants. Mixing incompatible coolants can lead to corrosion and system damage.
• Component Handling: Handle all components with care to prevent damage. Avoid touching electrical contacts.
• Environmental Conditions: Operate the system in a clean, dry environment. Avoid extreme temperatures and humidity.

4. Setup and Installation

This section provides a general overview. Refer to the detailed graphical instructions provided with your product for specific steps.

4.1. Preparation

• Ensure your system is powered off and unplugged.
• Carefully remove your NVIDIA GeForce RTX 4090 Founders Edition graphics card from your PC.
• Disassemble the stock cooler from the graphics card, following the manufacturer's guidelines. Clean the GPU die and memory chips of any residual thermal paste.

4.2. Installing the Water Block

• Apply thermal paste to the GPU die.
• Place the appropriate thermal pads on the memory modules and VRM components as indicated in the detailed manual.
• Carefully align and mount the Alphacool Eisblock Aurora GPX water cooler onto the graphics card. Secure it with the provided screws, ensuring even pressure.

4.4. Radiator and Fan Installation

• Mount the 360mm radiator and its three fans into an available 360mm fan mount location within your PC case. Ensure proper airflow direction.
• Connect the fan cables to the provided splitter and then to an appropriate fan header on your motherboard or fan controller.
• Connect any RGB cables from the fans and water block to your motherboard's RGB header or a dedicated RGB controller.

4.5. Final Assembly and Leak Test

• Install the assembled graphics card back into your PC's PCIe slot.
• Connect the pump's 3-pin power connector to a suitable fan header (e.g., AIO_PUMP or CPU_FAN) on your motherboard.
• Perform a thorough leak test. Power on the pump (without powering on the rest of the system) and inspect all connections for any signs of leakage. Allow the system to run for at least 24 hours during the leak test.
• Once leak testing is complete and no leaks are detected, power on your system.

5. Operating Instructions

The Alphacool Eiswolf 2 operates automatically once installed and powered. The DC-LT 2 pump continuously circulates coolant through the system, transferring heat from the GPU to the radiator, where it is dissipated by the fans.

• Monitoring: Use system monitoring software to observe GPU temperatures and fan speeds. Ensure temperatures remain within safe operating limits during load.
• Fan Control: Adjust fan curves in your motherboard's BIOS/UEFI or through software to balance cooling performance and noise levels.
• RGB Control: If connected, manage the Digital RGB lighting effects using your motherboard's RGB software or a compatible controller.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your liquid cooling system.

• Dust Cleaning: Periodically clean dust from the radiator fins and fans using compressed air. Ensure fans are held stationary during cleaning to prevent damage.
• Visual Inspection: Regularly inspect tubing, fittings, and the water block for any signs of leaks, kinks, or coolant discoloration.
• Coolant Replacement: While AIOs are generally maintenance-free regarding coolant, if the system is opened for modification or repair, use only compatible liquid cooling fluids.

7. Troubleshooting

• High GPU Temperatures:
  • Check fan operation: Ensure all radiator fans are spinning correctly and are connected.
  • Verify pump operation: Listen for pump noise or check monitoring software to confirm the pump is running.
  • Inspect thermal paste/pads: Ensure proper application and contact between the water block and GPU/components.
  • Radiator airflow: Ensure the radiator is not obstructed by dust or other components.
• No RGB Lighting:
  • Check RGB cable connections to the motherboard or controller.
  • Ensure RGB software is installed and configured correctly.
• Unusual Noises:
  • Fan noise: Check for obstructions or loose fan blades.
  • Pump noise: A slight hum is normal. Excessive noise might indicate air in the loop (which should settle over time) or a faulty pump.
• Leaks:
  • Immediately power off the system and disconnect power.
  • Identify the source of the leak.
  • Contact Alphacool support for assistance. Do not attempt to repair without guidance.
