Eisblock XPX Aurora Edge CPU Water Block

The Alphacool 12949 Eisblock XPX Aurora Edge is a nickel-plated copper CPU water block designed for custom liquid-cooling loops. It targets enthusiasts building high-performance systems who want efficient heat transfer combined with addressable digital RGB illumination.

34 x 32 mm cold plate with 81 micro-fins

The enlarged 34 x 32 mm cooling base covers large multi-core dies from 4 to 12-plus cores. Patented ramp flow technology distributes coolant evenly across 81 fins just 0.2 mm thick, maximising surface area until flow restriction becomes the limiting factor.

Dual G1/4 ports and 70 x 70 x 32.5 mm footprint

Two standard G1/4 threads accept common hard-tube or soft-tube fittings. The 70 mm square footprint fits most modern socket retention frames, while the 32.5 mm height clears standard motherboard heatsinks without requiring extra standoffs.

Questions about this item

Will the G1/4 ports on this block mate with the fittings I already use on my older loop?

Yes, the block provides two standard G1/4 threads so existing compression or barb fittings will connect directly.

How can I verify the addressable RGB is functioning correctly once the block is installed?

Connect the 3-pin 5 V ARGB header to a compatible motherboard or controller; the LEDs should cycle through colours immediately on power-up.

Does the package include mounting hardware for current Intel and AMD sockets or must I buy a separate kit?

The box contains the water block with pre-installed nickel-plated copper base, Plexi Chrome top, digital RGB lighting and G1/4 ports; a socket-specific mounting kit is not included.
