## Long description

The Alphacool Eisblock Aurora XP³ Light is a compact transparent Perspex CPU water block compatible with a wide range of current mainstream AMD and Intel sockets. The nickel-plated copper cold plate measures 56 x 56 mm and features a dense cross-slot pin array (1,156 pins, each 0.4 x 0.4 mm) to increase surface area for fluid flow and heat transfer. The pin area of about 27.6 x 37.6 mm covers most mainstream CPU heat spreaders. Nine addressable digital RGB LEDs arranged in a U-shaped layout provide extensive lighting, with a 3-pin 5V connector and integrated Y-adapter on the cable for daisy-chaining multiple Aurora devices. The block ships with a simple mounting bracket and illustrated manual for straightforward installation. Dimensions (product): 63 x 73 x 21 mm; colour: transparent.
Advantages
The design combines a nickel-plated copper cold plate and a high-density pin structure to deliver effective heat removal while keeping the block compact. Addressable digital RGB lighting with nine individually controllable LEDs enables flexible lighting setups and easy connection to standard 3-pin 5V controllers. The included mounting bracket and clear manual simplify assembly across supported sockets. The transparent Perspex top provides visual access to the coolant and lighting without affecting cooling performance.
Suitable for
Desktop PC cooling loops using mainstream Intel and AMD sockets
Custom water-cooling builds requiring a compact CPU water block
Systems where RGB lighting and visual coolant visibility are desired
Upgrading existing water-cooling setups with a transparent top block

How to use
Place the included mounting bracket over the CPU and pre-position the mounting screws onto the bracket as shown in the manual. Position the water block so the cold plate contacts the CPU heat spreader, then secure the block by tightening the screws evenly. Connect the 3-pin 5V RGB cable to a compatible addressable RGB controller; use the integrated Y-adapter to chain additional Aurora devices if required. Integrate the block into your loop using appropriate fittings and coolant, ensuring leak testing before powering the system.
Usage recommendations
Use compatible fittings and coolant recommended for PC water-cooling; perform a leak test outside the powered system for at least several hours. For full RGB control, connect to a 5V addressable RGB controller supporting individually addressable LEDs.
