The EK-Annihilator Pro Square ILM is a dedicated server grade water block with 1U chassis compatibility which was specifically developed for LGA 3647 (Socket P) Intel® processors. The core of the new CPU water block was further refined to manage the growing heat dissipation of new processors and to further upgrade connectivity options for server rack requirements. The new server/workstation-grade CPU block is 1U chassis type compatible for use with server racks.

EK-Annihilator Pro Square ILM

The EK-Annihilator PRO water block features a total of 9 ports, which allow for versatile connectivity options. Three ports located on the top are standard G1/4″ threaded and are intended for workstations and taller server racks, while the 6 side ports, for low profile usage, are G1/8″ threaded.

This enterprise cooling solution is built for performance, reliability, serviceability and no compromises in mind. The EK-Annihilator PRO water block meets these demands with top thermal performance, and unparalleled connectivity making it the perfect choice for liquid cooling high-density computing systems.

EK-Annihilator PRO water block features a precisely machined copper base (‘cold plate’) which is made from purest copper available on the market and is treated with nickel electroplating. The top is made from CNC machined from thick and sturdy black POM Acetal and the CPU square ILM and Square ILM hold-down brackets are made of laser cut stainless steel.
