High-Density Cooling for Intel Xeon 4th Gen Scalable
The EK-Pro CPU WB 4677 Ni + Acetal is designed for LGA 4677 Intel processors, offering enhanced heat dissipation for 4th gen scalable Xeon processors. With three G1/4" threaded ports, it suits workstations and taller server racks.
This enterprise-grade water block boasts top-notch thermal performance, reliability, and serviceability. Its copper base ensures optimal cooling, nickel electroplating enhances durability, and the CNC-machined black POM Acetal top adds resilience. The laser-cut stainless steel hold-down bracket ensures secure installation. Ideal for liquid cooling high-density computing systems, it meets demands for performance and connectivity.
Three design decisions worth calling out
Precision-Machined Copper Base
Pure copper base with nickel electroplating delivers optimal thermal conductivity and long-term corrosion resistance for continuous 24/7 operation under Xeon workloads.
Three Top-Mounted G1/4" Ports
Triple port layout accommodates a wide range of loop configurations in both workstation and server rack environments without requiring low-profile routing.
Laser-Cut Stainless Steel Bracket
The stainless steel hold-down bracket and CNC-machined black POM Acetal top ensure reliable clamping force and chemical resistance across the full operating temperature range.
