160W Liquid Cooling for Z Workstations

This internal power cable connects the 160W liquid cooling solution to compatible HP Z workstations. It supports the Z820, Z420, Z620, Z640 and Z440 models. The component ensures the cooler receives the power required for server-grade thermal management.

Sustained 160W heat dissipation

Under continuous load the cable delivers stable current to the liquid cooling unit, allowing it to maintain the 160W thermal capacity without throttling. Steady power flow prevents the pump and fan from cycling unpredictably during long rendering or compute sessions. The assembly is built for the sustained duty cycles typical of workstation and server environments.
