Lenovo 4H47B04172 SR630 V4 Cabled FAN for Cpu+mem DWC

Lenovo 4H47B04172 SR630 V4 Cabled Fan for CPU and Memory DWC

Overview

The Lenovo 4H47B04172 is a cabled fan module designed for CPU and memory direct water cooling (DWC) configurations in the ThinkSystem SR630 V4 rack server. When a SR630 V4 is deployed with a DWC thermal solution — common in high-density compute environments where air-cooled fan trays are replaced or supplemented — the 4H47B04172 provides the dedicated airflow required to maintain thermal margins across the CPU and memory subsystems. This is a replacement or spare component for data center operators maintaining SR630 V4 fleets running DWC workloads.

Compatibility

This fan is specific to the Lenovo ThinkSystem SR630 V4 platform in cabled DWC configurations. It is not a universal fan module and should not be substituted into non-DWC SR630 V4 builds or earlier SR630/SR630 V2/V3 generations. Confirm your SR630 V4 chassis is configured for cabled direct water cooling before ordering. For broader server components compatibility, cross-reference the Lenovo ServerProven list using your exact chassis serial and configuration.

Installation Notes

Installation requires working within a live DWC-configured SR630 V4 chassis. Ensure the server is powered down and coolant loops are depressurized before handling the fan module. The cabled interface means routing and connector seating must be confirmed before powering up — a partially seated connector will not trigger the expected fan-present signal and may cause thermal fault events. Weight is 10.00 lb; plan for two-person handling when servicing the chassis in a populated rack.
