Water block Alphacool 12847

The Alphacool XPX Eisblock (model 12847) is a CPU water block that combines high cooling performance with a distinctive visual design. Constructed with a mix of transparent nylon, black and white acrylic and a copper base, the block is built to resist tensile stress and temperature differences while providing a clear or satin appearance depending on the finish. Its cooling base measures 34 x 32 mm and the unit is compatible with a wide range of CPU sockets including LGA 115x, LGA 2011-v3, LGA 1366, AM4 and many older AMD/Intel sockets.

Advantages

The transparent nylon construction offers greater resistance to tension and cracking than conventional Plexiglas while allowing a visually clear coolant channel. A satin (milky) finish option diffuses lighting for a softer look. Internally polished channels make the cooler appear completely clear and Alphacool’s patented ramp technology distributes coolant evenly over the entire cooler base for improved thermal transfer. The frame is swap‑able for color customization.

Suitable for

• Custom liquid‑cooled desktop PCs
• High core‑count CPUs (8 cores or more)
• Enthusiast builds where aesthetics and lighting are important
• Systems requiring durable transparent coolant channels

How to use

Install the Alphacool XPX Eisblock following your motherboard and case manufacturer instructions for water‑block mounting and socket compatibility. Replace the stock frame with a different color frame if desired before final mounting. Connect the water block to your custom loop using appropriate fittings and tubing, ensure the loop is filled and leak‑tested, then run the cooling system while monitoring temperatures to confirm correct operation. Use thermal paste between the CPU and copper base per standard practice.

Recommendations

Use the clear version to showcase internal coolant and RGB lighting, or the satin version to diffuse lighting for softer color effects. Always perform a pressure/leak test after installation and verify socket compatibility with the supplied mounting hardware.
