Water block EK Water Blocks Nickel LGA 4677

The EK Water Blocks 3831109861110 Nickel LGA 4677 is an enterprise-grade CPU water block engineered for efficient liquid cooling of LGA 4677 Intel® Xeon processors. Designed for 1U chassis compatibility and server-rack environments, this water block combines a nickel-plated copper coldplate with a CNC-machined POM acetal top and a stainless steel hold-down bracket to deliver durable construction, reliable thermal transfer and low-profile connectivity. The product includes threaded side ports and a compact accessory set for installation and maintenance.

Advantages

The nickel-plated copper coldplate provides high thermal conductivity while the nickel treatment improves corrosion resistance and surface durability. The black POM acetal top is CNC-machined for tight tolerances and long-term reliability in dense rack systems. Four G1/8" side ports allow flexible low-profile tubing routing in 1U chassis, and the included accessory kit simplifies installation and servicing. The unit is purpose-built for high-density computing where consistent thermal performance and serviceability are required.

Suitable for

• Liquid cooling of LGA 4677 Intel® Xeon processors in server and workstation systems
• 1U rack-mounted chassis and other low-profile server enclosures
• High-density compute nodes and blade or microserver configurations
• Custom liquid-cooling loops where compact side porting is needed

How to use

Mount the water block onto an LGA 4677 CPU according to the server or motherboard manufacturer’s mounting procedure, using the provided stainless steel hold-down bracket and the supplied Allen and Torx keys to achieve proper torque. Route low-profile tubing to one of the G1/8" side ports and secure fittings or plugs as required. Apply the supplied thermal grease to the CPU surface before seating the coldplate to ensure optimal thermal contact. Verify leak-tight connections and perform a pressure and leak test before powering the system.

Recommendations

Use compatible G1/8" fittings and low-profile tubing designed for 1U environments. Maintain the cooling loop with appropriate corrosion inhibitors and biocides where required, and follow standard rack airflow and case clearance guidelines. During installation, tighten fasteners progressively and evenly to avoid uneven pressure on the coldplate. Periodically inspect fittings and seals for wear and reapply thermal interface material if the block is removed for servicing.
