EK Water Blocks EK-Pro CPU WB 4189 Rack Ni + Acetal

EK-Pro CPU WB 4189 Rack – Nickel + Acetal Enterprise-Grade CPU Water Block for Intel® LGA 4189 – Rack-Optimized and 1U-Compatible The EK-Pro CPU WB 4189 Rack – Nickel + Acetal is a high-performance CPU water block designed specifically for Intel® LGA 4189 processors, optimized for 1U rack chassis. It’s built to deliver outstanding thermal performance, serviceability, and reliability, making it an ideal choice for enterprise-grade applications in dense server environments. To meet the increasing heat dissipation needs of modern CPUs, the water block features a nickel-plated pure copper cold plate, CNC-machined for maximum contact and efficiency. The top is crafted from durable black POM Acetal, while the hold-down bracket is made from laser-cut stainless steel, ensuring long-term mechanical integrity in continuous operation. The block includes four G1/8” side ports, allowing flexible and low-profile tubing arrangements — ideal for use in compact 1U server environments. Its refined internal design is engineered for high flow efficiency and stability, even in demanding rack-mounted systems. With no compromises on performance or build quality, the EK-Pro CPU WB 4189 Rack offers exceptional cooling, robust mounting, and enterprise-ready design.
