All-in-one liquid cooler Alphacool Eisbaer Aurora LT240 12 cm Black

The Alphacool Eisbaer Aurora LT240 is an all-in-one (AIO) CPU liquid cooler that combines custom-water-cooling components with a compact, ready-to-install design. It includes a full copper, nickel-plated cold plate and radiator parts derived from Alphacool’s custom and enterprise cooling product lines. The unit uses a DC-LT 2 pump and comes with quick-release fittings and ES-series TPV tubing, allowing easy expansion of the loop or replacement of hoses and fittings.

Advantages

The Eisbaer Aurora LT240 delivers high cooling performance thanks to a full copper coolant path and finely engineered cooling fins with a flow plate that evens and accelerates coolant across the cold plate. The DC-LT 2 pump features a ceramic axle and magnetic support with a 3-phase sinusoidal drive for smoother operation and reduced noise. ES-series TPV tubing resists deformation at high temperatures and contains no plasticizers. Digital Addressable RGB (aRGB) lighting is provided on the pump and fans, including an illuminated polar bear emblem, with daisy-chain capability for simpler cable routing.

Suitable for

• High-performance desktop CPUs in gaming rigs and workstations
• Systems where loop expansion is desired (adding GPU blocks or additional radiators)
• Builds requiring low-noise pump operation and robust tubing
• Setups with motherboard or controller aRGB support for synchronized lighting

How to use

Install the Eisbaer Aurora LT240 by mounting the radiator and fans in the desired case location, then place the nickel-plated copper cold plate on the CPU with thermal paste. Connect the pump and fans to the motherboard headers or the included controller for power and aRGB control. The quick-release fitting allows you to extend the loop: power down the system, disconnect via the connector, add compatible components with G1/4" threads, then reconnect and refill or top up if required. Follow the motherboard or controller instructions to configure pump and fan speeds and lighting effects.

Recommendations

For reliable long-term operation, use compatible G1/4" fittings for any loop expansions, avoid PVC hoses to prevent deformation at high temperatures, and ensure the pump receives stable power. If adding a GPU AIO or extra radiator, check pump capacity and monitor temperatures after completion. Use the included aRGB controller or motherboard software to manage lighting and daisy-chain the devices for cleaner cabling.
