Lenovo 4H47B04173 SR630 V4 Cpu+mem DWC Module

Lenovo 4H47B04173 SR630 V4 CPU and Memory Direct Water Cooling Module

Overview

The Lenovo 4H47B04173 is a direct water cooling (DWC) module designed for the ThinkSystem SR630 V4 rack server platform, providing processor and memory thermal management for high-density compute deployments where air cooling reaches its limits. Manufactured in Mexico and classified under UNSPSC 43211600 (electronic components and supplies), this module is a precision server component — not a drop-in accessory. Installation requires careful integration planning within the SR630 V4 chassis and a compatible facility-side liquid cooling infrastructure.

At 10 lb, the 4H47B04173 carries meaningful mass for a server module, consistent with the cold plate assemblies, manifolds, and coupling hardware typical of enterprise DWC solutions. If you are sourcing this for a data center retrofit or a new high-performance compute buildout on the SR630 V4 platform, confirm your facility liquid loop specifications and coolant compatibility before ordering.

Key Features

• Direct Water Cooling Architecture: DWC removes heat directly from the CPU and memory via liquid rather than relying solely on airflow — a practical necessity in high-core-count, high-TDP server configurations where chassis airflow alone cannot maintain thermal headroom. This translates to more consistent sustained performance under prolonged compute loads.
• SR630 V4 Platform Specificity: The 4H47B04173 is engineered for the ThinkSystem SR630 V4. Platform-specific fit matters here — DWC cold plates are not interchangeable across server generations or OEMs. Verify your exact chassis generation before ordering.
• Factory-New, Commercial-Grade Component: Sourced as a genuine, factory-new Lenovo part — no refurbished or grey-market substitutes. For thermal management components in production servers, component integrity directly affects reliability.
• 10 lb Module Weight: At 10.00 lb, plan for the additional load on your server rail and rack weight budget, particularly in fully populated 2U deployments where multiple heavy components are installed simultaneously.
• Mexico Manufacturing Origin: Produced in Mexico under Lenovo's manufacturing quality standards, consistent with the broader ThinkSystem server line.

Integration and Compatibility

The 4H47B04173 is purpose-built for the Lenovo ThinkSystem SR630 V4 server. Compatibility outside of this platform is not confirmed by available evidence. Liquid cooling deployments require facility-side infrastructure — supply and return manifolds, coolant distribution units (CDUs), and appropriate coolant type — that must be validated independently of this module. Consult Lenovo's SR630 V4 installation documentation and your facilities team before commissioning.

For broader server and storage components or to explore the Lenovo server catalog, additional platform options are available. If you are evaluating rack server cooling strategies, direct water cooling becomes relevant when average rack power density exceeds approximately 15–20 kW per rack — at that point, server accessories and thermal management components like this module become infrastructure decisions, not afterthoughts.

Frequently Asked Questions

Q: What server platform is the Lenovo 4H47B04173 compatible with?

A: The 4H47B04173 is designed for the Lenovo ThinkSystem SR630 V4 rack server. Compatibility with other platforms or server generations is not confirmed by available evidence — verify your chassis model before ordering.

Q: What does DWC mean for the SR630 V4?

A: DWC stands for Direct Water Cooling. The module removes heat from the processor and memory via a liquid cooling loop rather than airflow alone, which is important for high-TDP CPU configurations where air cooling is insufficient to maintain thermal limits under sustained load.

Q: How much does the 4H47B04173 weigh?

A: The module weighs 10.00 lb. Factor this into your rack weight budget and rail load calculations, especially in fully populated 2U configurations.

Q: Is the 4H47B04173 a new or refurbished component?

A: This is a factory-new, genuine Lenovo component sourced through commercial distribution channels — not refurbished or grey-market.

Q: Where is the 4H47B04173 manufactured?

A: The module is manufactured in Mexico, consistent with Lenovo's ThinkSystem production standards.

Karl Wilson

The 4H47B04173 is a platform-specific thermal component, and that specificity is the most important thing to understand before ordering. At 10 lb, this DWC module is not a light bracket swap — it is a precision cold plate and manifold assembly for the SR630 V4 CPU and memory subsystem, and it only makes sense in environments where liquid cooling infrastructure is already in place or being built out alongside the server deployment.

Technical Highlights:

• Direct Water Cooling Target: CPU and memory thermal management via liquid loop — addresses the core limitation of air-cooled high-density compute where sustained TDP drives chassis temperatures above safe operating margins.
• Module Weight (10 lb): Heavier than a typical server accessory — rack rail load ratings and total chassis weight must be recalculated before finalizing the physical deployment plan.
• SR630 V4 Platform Lock: Not a universal fit. The cold plate geometry, manifold connections, and mounting points are specific to this server generation — cross-platform substitution is not viable.

Deployment Considerations:

• Facility-side liquid cooling infrastructure — CDU, supply/return manifolds, coolant type and pressure — must be validated before this module can be commissioned. The module alone does not create a cooling loop.
• Watch out for chassis generation mismatch: SR630 V4 is distinct from SR630 V2 and other ThinkSystem 2U variants. Confirm the exact server generation with the Lenovo chassis serial or sales order before procurement.

The 4H47B04173 is the right call for high-density AI inference or HPC workloads on the SR630 V4 where sustained CPU TDP pushes the limits of what the standard air cooling path can handle — specifically in facilities already running or planning a rack-level liquid cooling deployment.
