What customers say
Enthusiasts highly regard the Alphacool Eisbaer Pro Aurora 420 for its exceptional thermal performance, easily managing extreme heat from high core count processors. A key strength is its superior modularity; the standard G1/4 fittings allow seamless integration into custom loops, significantly boosting long term utility. Users consistently note the robust, premium build quality, which supports its higher cost. While the massive 420mm size presents case compatibility challenges for some, the consensus is clear: this is a specialized, high performance cooling solution for users prioritizing top tier cooling power and future expandability over simple installation.
Know before you buy
This cooler supports a wide range of sockets, including Intel 775, 115x, and 20xx series, as well as AMD AM2, AM3, AM4, and TR4. Please verify your specific motherboard socket type before installation to ensure a proper fit.
Yes, the Eisbaer Pro Aurora 420 is designed for expandability. It features standard G1/4 fittings and a refillable loop, allowing you to easily integrate additional components like GPU blocks or extra radiators into the system.
The radiator is constructed from full copper rather than aluminum. Copper offers superior thermal conductivity, which allows for more efficient heat dissipation and better long-term cooling performance for your CPU.
The addressable RGB lighting is controlled directly through your motherboard's software. This allows you to sync the lighting effects on the pump and fans with the rest of your system components without needing proprietary controller software.
The radiator measures 468 x 144 x 30 mm. Before purchasing, ensure your PC case explicitly supports 420mm radiators, as this is a large unit that requires significant clearance in the top or front mounting positions.
The upgraded pump operates at 2800 rpm and is engineered for a 10% increase in power while maintaining lower noise levels than previous iterations. It provides a balance of high flow rates and quiet operation suitable for high-performance builds.
