EK-Pro CPU WB 4189 Rack

Product EAN: 3831109844700

High-performance 1U-compatible water block for LGA 4189 Intel processors with four G1/8" threaded side ports for low-profile server rack applications.

Compatibility: LGA 4189
Platform: Intel

Overview

1U Server Cooling for Intel LGA 4189

The EK-Pro CPU WB 4189 Rack Ni + Acetal is a high-performance water block designed for LGA 4189 Intel processors, optimized for 1U chassis compatibility. It features four G1/8" threaded side ports for low-profile usage and boasts top thermal performance.

The block's copper base is nickel electroplated, while its top is CNC machined from durable black POM Acetal. The hold-down bracket is laser-cut stainless steel, ensuring reliable installation and long-term structural integrity in rack-mounted server systems.

Key Engineering

Three design decisions worth calling out

1U Low-Profile Design

Side-mounted G1/8" ports allow full coolant loop connectivity within the height constraints of 1U rack chassis running Intel LGA 4189 processors.

Laser-Cut Stainless Steel Bracket

T30 Torx fasteners and a laser-cut stainless steel hold-down bracket deliver uniform clamping force and long-term stability in rack-mount server systems.

Nickel-Plated Copper + POM Acetal

Electroplated copper base and CNC-machined black POM Acetal top provide corrosion resistance and chemical compatibility with standard water cooling fluids.
