Introduction
The Alphacool Eisbaer Pro Aurora 360 CPU All-in-One (AIO) water cooler is engineered for high-performance processors, particularly those with large CPU cores such as AMD Threadripper and Epyc, as well as Intel CPUs utilizing LGA 3647 and LGA 4189 sockets. This AIO solution combines efficient cooling with customizable aesthetics, featuring addressable digital RGB LEDs on both the cooler and the fans.
The system is designed to be expandable and fully compatible with custom DIY water cooling components, offering flexibility for advanced users. It is an optimal cooling solution for demanding processors, ensuring stable operation under heavy loads.
Safety Information
- Always disconnect power from your computer system before installation or maintenance.
- Handle components with care to avoid damage. Avoid touching the thermal paste or the cold plate surface directly.
- Ensure all connections are secure to prevent leaks. Regularly inspect the system for any signs of leakage.
- Do not operate the pump dry. Ensure the loop is filled with coolant before powering on.
- Keep out of reach of children.
- If any liquid comes into contact with skin or eyes, rinse immediately with plenty of water and seek medical attention if irritation persists.

Setup and Installation
Follow these general steps for installing your Alphacool Eisbaer Pro Aurora 360 CPU cooler. Refer to your motherboard and PC case manuals for specific instructions regarding component placement and cable routing.
1. Prepare the CPU and Motherboard
- Ensure your motherboard is installed in the PC case.
- Clean the CPU surface thoroughly with isopropyl alcohol to remove any dust or old thermal paste.
- Apply a small amount of the provided thermal paste to the center of the CPU's Integrated Heat Spreader (IHS).
2. Install Mounting Hardware
Select the appropriate mounting bracket for your CPU socket (AMD or Intel) from the included accessories.

- Attach the correct backplate (if required for your socket) to the rear of the motherboard.
- Secure the standoffs to the motherboard's CPU socket mounting holes.
- Place the CPU block onto the CPU, aligning the mounting holes with the standoffs.
- Secure the CPU block with the provided thumb nuts or screws. Important: Tighten the nuts firmly and evenly in a cross pattern until the block is securely seated. Over-tightening can damage components, but insufficient tightening can lead to poor thermal contact and high temperatures.
3. Mount the Radiator
Identify a suitable mounting location for the 360mm radiator in your PC case (e.g., top, front, or bottom panel). Ensure adequate airflow.

- Position the radiator and secure it to the case using the long screws provided. Ensure the fans are oriented to provide optimal airflow (intake or exhaust, depending on your case's airflow design).
4. Connect Cables

- Connect the pump's 4-pin power cable to a dedicated AIO_PUMP or CPU_FAN header on your motherboard.
- Connect the fan cables to the CPU_FAN or SYS_FAN headers on your motherboard, or to a fan controller.
- Connect the digital RGB cables from the fans and pump block to a compatible 3-pin 5V addressable RGB header on your motherboard or an RGB controller.
Operating Instructions
Once installed, the Alphacool Eisbaer Pro Aurora 360 operates automatically, with the pump and fan speeds controlled by your motherboard's BIOS/UEFI settings or dedicated software.
- Fan Control: The 120mm Aurora Rise fans feature PWM control, allowing for a wide speed range and zero RPM control for silent operation under low loads. Adjust fan curves in your motherboard's BIOS/UEFI or using software provided by your motherboard manufacturer.
- RGB Lighting: The addressable digital RGB LEDs on the fans and pump can be customized using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync) or a standalone RGB controller.
- Initial Startup: Upon first power-on, the pump will prime the loop. You may hear some gurgling noises initially, which should subside as air bubbles are purged from the system.
Maintenance
The Alphacool Eisbaer Pro Aurora 360 is designed for low maintenance, but periodic checks are recommended to ensure optimal performance and longevity.
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are not spinning during cleaning.
- Leak Inspection: Regularly inspect all connections and tubing for any signs of leaks or moisture. Address any issues immediately.
- Coolant Level (Optional): The Eisbaer Pro Aurora is an expandable system. It features G1/4" connections and a fill port, allowing for refilling or integration into a custom loop. If you notice a significant drop in performance over time, or if you are integrating it into a larger loop, you may need to check and top up the coolant level.
- Quick-Release Mechanism: The system includes quick-release couplings for easy expansion or maintenance without draining the entire loop.
