Alphacool Eisblock XPX Aurora Pro Light CPU Water

The Alphacool 12981 Eisblock XPX Aurora Pro Light is a nickel-plated copper CPU water block designed for custom liquid-cooling loops. It features a clear plexi top with 14 addressable 5 V aRGB LEDs and a 3-pin JST connector with an included Y-adapter. The cold plate uses 147 fins over a 42 x 58.6 mm area optimised for large processor dies.

Suited for high-end desktop and workstation sockets

This block targets builders using Intel LGA 2011, LGA 2066 or LGA 3647 platforms plus AMD Threadripper TR4, TRX40 and SP4 sockets. It provides two G1/4 threads for standard fittings. Buyers with mainstream desktop processors cannot use this block because the mounting pattern is specific to the larger HEDT and server sockets listed.

147 fins across 42 x 58.6 mm cold-plate area

The fin array covers the full surface of large CPU heatspreaders to maximise thermal transfer. Nickel-plated copper construction ensures high conductivity. The 63.8 x 79 x 22.5 mm footprint and integrated aRGB lighting complete the specification that determines fit and performance.

Questions about this item

What limits cooling performance during sustained loads?

The 147 cooling fins covering a 42 x 58.6 mm area set the thermal transfer ceiling for this copper cold plate.

How much heat and noise does the block add when running all day?

The nickel-plated copper block itself produces no noise and negligible heat; all thermal load and pump noise come from the rest of your loop.

Which mounting hardware must I already own for this block to fit?

You need the correct Alphacool mounting kit for Intel LGA 2011, 2066, 3647 or AMD Threadripper TR4, TRX40, SP4 sockets.
