3. Installation Guide

This section provides general guidelines for installing the Alphacool Eisbaer Aurora 280 CPU liquid cooler. Refer to the detailed online manual for specific steps related to your CPU socket type.

3.1. Preparation

1. Ensure your system is powered off and disconnected from the power source.
2. Prepare your CPU socket by cleaning the CPU surface and applying thermal paste (if not pre-applied).
3. Identify the correct mounting brackets and screws for your motherboard's CPU socket.

3.2. Radiator and Fan Installation

1. Mount the two 140mm fans to the radiator using the provided screws. Ensure the fan airflow direction is appropriate for your case's cooling setup (intake or exhaust).
2. Install the radiator assembly into an available 280mm fan mount location in your PC case.

3.3. Pump Block Installation

1. Secure the appropriate backplate (if required) to the rear of your motherboard.
2. Position the pump block over the CPU, aligning it with the mounting holes.
3. Fasten the pump block to the motherboard using the designated screws and standoffs. Tighten screws evenly in a cross pattern to ensure proper contact pressure.

3.4. Cable Connections

• Connect the pump's power cable to a SATA power connector from your power supply.
• Connect the fan PWM cables to available 4-pin fan headers on your motherboard or to a fan controller. Note: A fan splitter may be required if your motherboard has insufficient headers.
• Connect the digital RGB cables from the pump and fans to a compatible 3-pin JST + 3-pin 5V digital RGB header on your motherboard or an external RGB controller.

4. Operating Instructions

4.1. Initial Startup

Upon first power-up, the pump may produce some noise as air bubbles are cleared from the loop. This is normal and should subside within a few minutes. Monitor CPU temperatures to ensure proper cooling.

4.2. RGB Lighting Control

The Eisbaer Aurora 280 features addressable RGB lighting on both the pump and fans. Control the lighting effects and colors using:

• Motherboard Software: If connected to a compatible motherboard's digital RGB header, use the motherboard manufacturer's RGB control software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion).
• External RGB Controller: If using an external digital RGB controller, refer to the controller's specific instructions for customization.

5. Maintenance

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

5.1. Dust Cleaning

• Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Excessive dust can impede airflow and reduce cooling efficiency.

5.2. Coolant Refilling and Expansion

The Eisbaer Aurora 280 is designed to be refillable and expandable.

• Refilling: Over time, a small amount of coolant may evaporate. The pump block features a fill port (typically a screw on top) for adding coolant. Use only Alphacool-approved coolants to prevent corrosion or damage.
• Expansion: The system uses G1/4" fittings and quick-release fasteners, allowing for easy integration into a larger custom loop or expansion with additional components like GPU blocks or extra radiators.
