Vandkøler Alphacool 12949

The Alphacool 12949 Eisblock XPX Aurora Edge water block is a compact CPU cooling solution in grey and black, made of acrylic and copper. It uses Alphacool's patented ramp flow system and an enlarged coolant channel area to improve heat transfer from modern multi-core CPUs. The block integrates addressable digital RGB LEDs around the cooling housing for adjustable illumination and includes a Y-adapter on the cable for easy daisy-chaining of other Alphacool Aurora products.

Advantages

The patented ramp design evens the coolant flow across the diffuser plate to press water uniformly over the cooling base, while the enlarged cooling channel (34 x 32 mm) and 81 thin fins (0.2 mm) increase surface area for efficient heat diffusion. Integrated aRGB LEDs (up to 15 LEDs) provide uniform lighting around the block and can be controlled via a compatible controller or a 3-pin 5V motherboard header. The product is compact (70 x 70 x 32.5 mm) and compatible with a wide range of Intel and AMD sockets.

Suitable for

• Enthusiast and custom liquid-cooled desktop PCs
• Multi-core processors (4, 6, 8, 12+ cores) requiring enhanced heat dissipation
• Systems where integrated aRGB lighting and series connection of Aurora components are desired

How to use

Attach the supplied backplate to the rear of the motherboard, clamp the appropriate mounting frame (Intel or AMD) to the cooler, and ensure the pre-attached mounting screws are aligned. Apply a thin, even layer of thermal paste to the CPU heatspreader, position the water block over the socket, and secure it with the provided screws according to the torque guidelines of your motherboard or CPU cooler manual. Connect the aRGB cable to a compatible 3-pin 5V header or controller; use the included Y-adapter to chain additional Aurora devices if required. If routing multiple devices in series in larger cases, consider optional extension cables.

Recommendations

For optimal performance, verify compatibility with your motherboard socket and plan tubing and cable routing before installation. Use a compatible 5V ARGB controller or motherboard header to manage lighting effects, and follow the system manufacturer's guidance for mounting torque and leak testing when integrating into a custom loop.
