Water block Alphacool 11760

The Alphacool Aurora Plexi GPX Eisblock is a transparent acrylic water block for graphics cards that combines extensive addressable RGB illumination with a copper cooling core. Designed as a complete redevelopment of previous Alphacool GPU blocks, the Aurora Plexi GPX focuses on improved thermal performance and integrated lighting while preserving high manufacturing quality. Dimensions: 122 mm (width) x 266.5 mm (depth) x 25 mm (height). The product uses nickel-plated copper for the cooling core and a clear plexi top for visual integration into custom liquid-cooling loops.

Advantages

The cooler increases thermal contact by using 1 mm Alphacool Eisschicht Ultra Soft heat-conducting pads that conform closely to components and reduce pressure compared with thicker pads. The copper cold plate thickness has been optimized (reduced from 7 mm to 5.5 mm) and the internal coolant channels are refined to improve flow and heat transfer for memory and VRM components. Addressable digital RGB LEDs are embedded along the length of the block for uniform illumination, while improved nickel plating enhances corrosion and acid resistance to reduce the risk of flaking.

Suitable for

• Custom PC water-cooling loops for graphics cards
• High-performance GPU cooling where visual RGB integration is desired
• Systems requiring effective cooling of GPU memory and VRMs

How to use

Install the water block onto a compatible graphics card following the manufacturer's compatibility list and mounting instructions. Place the 1 mm thermal pads on the GPU, memory, and VRM contact areas as indicated, then align the block and secure the mounting hardware to achieve even pressure. Connect the aRGB LED cable to a compatible addressable RGB header or controller. Integrate the block into your custom loop using appropriate fittings; IN and OUT ports are marked by small triangles on the terminal. Verify leak-tight connections and perform a leak test before powering the system.

Usage recommendations

Use corrosion-inhibiting coolant compatible with mixed-metal loops, avoid aluminum radiators in contact with copper unless appropriate inhibitors are used, and follow Alphacool’s mounting torque and leak-test guidance. For best lighting results, pair the block with a compatible aRGB controller and ensure even flow through the GPU channel for optimal cooling of memory and VRMs.
