The EK-Annihilator EX/EP 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 new 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.
