Coolant Alphacool Eisbaer Pro Aurora Acrylic Copper Nickel 1/4 inch

The Alphacool Eisbaer Pro Aurora is a liquid cooler designed for very large CPU dies, offering a substantially larger cold plate and fin area than the standard Eisbaer Aurora. It fully covers large processors such as AMD Threadripper and is also compatible with AMD Ryzen and Intel Socket 3647 CPUs. The unit is expandable and compatible with DIY water-cooling components, providing a compact, integrated solution for high-performance processors.

Advantages

The cooler's cold plate bottom measures approximately 55 x 42 mm, covering CPU hotspots directly for improved heat transfer. The fin stack consists of 58 fins with a thickness of 0.4 mm and a 0.4 mm gap between fins; the cooler base is 3 mm thick to allow rapid heat conduction into the coolant. A compact DC-LT 2 pump provides sufficient flow to add other components (for example a GPU water block or additional radiators) into the same loop. Addressable digital RGB LEDs are integrated across the unit and can be controlled via compatible RGB controllers.

Suitable for

• Large CPU dies such as AMD Threadripper
• AMD Ryzen processors (using included AM4 bracket)
• Intel systems with Socket 3647
• Custom and expandable DIY water-cooling loops

How to use

Install the Eisbaer Pro Aurora following the manufacturer's mounting instructions for your socket: use the included AM4 bracket for AMD Ryzen CPUs or the appropriate mounting hardware for Threadripper and Intel Socket 3647. Connect the 1/4" fittings to your loop and ensure secure, leak-free seals. Power the pump and RGB header(s) via the appropriate motherboard or controller connections. If integrating additional water-cooling components, plan the loop layout to maintain adequate flow and cooling performance.

Recommendations

For optimal results, ensure the cold plate fully contacts the CPU heat spreader and use compatible coolant and fittings. Verify pump power and loop complexity when adding multiple components to maintain sufficient flow. Use a compatible digital RGB controller to manage lighting effects.
