The EK-Annihilator EX/EP Square is a dedicated server grade water block with 1U chassis compatibility which was specifically developed for LGA 3647 (Socket P) Intel® processors. The entire CPU block was designed from the ground up to fit the requirements of the Square ILM socket and to integrate multiple connectivity options for server rack requirements. With that said, the new server-grade CPU block is 1U chassis type compatible for use server and workstation type motherboards.

EK-Annihilator Square

This enterprise solution is built for performance, reliability, serviceability and no compromises in mind. The EK-Annihilator EX/EP Square water block meets these demands with low hydraulic restriction and top thermal performance making it the perfect choice for liquid cooling high-density computing systems.
