## High-Density Cooling for Intel LGA 4189 Processors

The EK-Pro CPU WB 4189 Ni + Acetal is an enterprise-grade water block tailored for LGA 4189 Intel processors, designed to manage increased heat dissipation and enhance connectivity options for workstations. Featuring three standard G1/4" threaded ports on the top, it caters to workstation and server rack requirements.

Constructed with a pure copper base treated with nickel electroplating and a CNC-machined black POM Acetal top, it ensures durability and efficient heat dissipation for liquid cooling high-density computing systems.

### Precision-Machined Copper

Pure copper base with nickel electroplating provides optimal thermal conductivity and corrosion resistance for the LGA 4189 socket footprint.

### Three Top-Mounted G1/4" Ports

Triple top port layout supports flexible loop routing in workstations and tall-chassis server racks where overhead port access simplifies tube management.

### CNC POM Acetal Top

CNC-machined black POM Acetal top ensures chemical compatibility with common coolants and mechanical durability over extended service intervals.
