## 1U Liquid Cooling for AMD EPYC SP5 in Dual-Socket Servers

The EK-Pro CPU WB SP5 Rack Ni + Acetal is a high-performance water block designed for AMD socket SP5-based processors with up to 96 cores and 192 threads. Specifically built for 1U chassis compatibility, it is ideal for liquid cooling in dual-socket server environments.

Featuring four G1/8" threaded side ports, it offers seamless connectivity and top thermal performance. Constructed with a pure copper base, nickel electroplating, black POM Acetal top, and stainless steel bracket, it ensures durability and reliability for high-density computing systems.

### 1U Dual-Socket Compatible

Sized and ported for 1U chassis running dual AMD EPYC SP5 processors, where low-profile side-port access is required to maintain chassis height compliance.

### Four Side-Mounted G1/8" Ports

Quad port layout provides independent inlet, outlet, and additional connections for dual-socket loops, enabling flexible coolant distribution across both sockets.

### Copper Base + Stainless Steel Bracket

Nickel-plated copper base and stainless steel hold-down bracket with T20 Torx fasteners deliver long-term structural integrity and consistent thermal interface pressure.
