Lenovo 4H47B03713 SR650/A V4 2U Performance Heatsink

Lenovo 4H47B03713 SR650/A V4 2U Performance Heatsink

Overview

The Lenovo 4H47B03713 is a 2U rack-form-factor performance heatsink designed for the ThinkSystem SR650 and SR650 V4 server platforms. At 10 lb, this is a substantial copper-and-aluminum thermal assembly built to handle the sustained CPU thermal loads that arise in dense, continuously running data center and edge compute environments. If your SR650/A V4 is configured for higher-TDP processors or operating in an elevated ambient environment, the 4H47B03713 is the purpose-built thermal solution — not a generic aftermarket substitute.

Sourced factory-new from channel-direct distribution, this is a genuine Lenovo component manufactured in Mexico (MX), carrying UNSPSC commodity code 43201538 (Computer Cooling Components). That classification matters for procurement teams running commodity-coded purchasing workflows — the part will resolve cleanly in any compliant catalog system.

Key Features

• 2U Rack Form Factor: Designed to fit within the 2U chassis envelope of the SR650/A V4 — no modification, no clearance guesswork. If you are populating or refreshing an SR650 chassis, this heatsink installs to Lenovo's mechanical specification without rework.
• Performance-Grade Thermal Capacity: The "Performance" designation in the product name indicates this heatsink is rated for higher-TDP CPU configurations versus the standard heatsink option. Deploying high-core-count or high-TDP processors in the SR650/A V4 without the correct heatsink risks thermal throttling under sustained load — the wrong heatsink is a common cause of unexplained compute performance degradation in dense racks.
• 10 lb Solid Construction: The 10 lb weight reflects the fin stack and base plate mass required for adequate thermal transfer at performance-tier TDPs. Expect a deliberate, tool-assisted installation — this is not a clip-on accessory.
• Genuine Lenovo Component (MX Origin): Manufactured in Mexico under Lenovo's production standards. No grey-market, no parallel imports — critical for environments where hardware provenance affects support contract validity.

Integration & Compatibility

The 4H47B03713 is specified for the Lenovo ThinkSystem SR650 and SR650 V4 (including the SR650 A variant) 2U rack server family. Confirm your exact chassis generation and CPU TDP before ordering — Lenovo publishes heatsink selection guidance by processor TDP in the SR650 V4 product guide. Installing a performance heatsink in a chassis configured for standard TDP CPUs is harmless; installing a standard heatsink under a performance-TDP CPU is not. When in doubt, the performance heatsink is the safer selection.

For broader server infrastructure components or compatible server accessories, verify chassis generation compatibility against Lenovo's published compatibility matrix before procurement.

Frequently Asked Questions

Q: Which server platforms is the 4H47B03713 compatible with?

A: The 4H47B03713 is specified for the Lenovo ThinkSystem SR650 and SR650 V4 (SR650/A V4) 2U rack server family. Verify your specific chassis generation and processor TDP requirements against Lenovo's official compatibility documentation before ordering.

Q: What does the "Performance" designation mean for this heatsink?

A: The Performance designation indicates this heatsink is rated for higher-TDP CPU configurations in the SR650/A V4 platform, as opposed to the standard heatsink option. It is the correct choice when deploying high-core-count or high-TDP processors that exceed the thermal capacity of the standard heatsink.

Q: What is the weight of the 4H47B03713?

A: The 4H47B03713 weighs 10 lb. Plan for tool-assisted installation and verify that your chassis rail and CPU socket retention mechanism can support the heatsink mass during handling.

Q: Is this a genuine Lenovo part or an aftermarket component?

A: This is a genuine Lenovo component, manufactured in Mexico (country of origin: MX), sourced through channel-direct distribution. No grey-market, no parallel imports.

Q: What is the UNSPSC code for this part?

A: The UNSPSC code is 43201538 (Computer Cooling Components), which resolves correctly in commodity-coded procurement and catalog systems.

The 4H47B03713 is one of those parts that only matters when it's wrong — and when it's wrong, you find out under load. At 10 lb, this is a full-mass performance heatsink for the SR650/A V4 platform, not a lightweight standard-config option. If you are specifying high-TDP processors in an SR650 V4 deployment, this is the correct thermal component to specify alongside the CPU.

Technical Highlights:

• 2U Form Factor Fit: Engineered to the SR650/A V4 2U chassis envelope — installs without modification or clearance conflict in a properly configured SR650 rack unit.
• 10 lb Thermal Mass: The weight reflects the fin stack and copper base plate required for performance-TDP heat dissipation. Standard-config heatsinks in the same platform family are measurably lighter — the mass difference is the thermal headroom difference.
• Genuine Lenovo, MX Origin: Country of origin Mexico, distributed channel-direct. Relevant for federal procurement and support contract validity — Lenovo support teams will ask about component provenance when troubleshooting thermal events.

Deployment Considerations:

• Confirm CPU TDP mapping before specifying: Lenovo publishes heatsink selection tables by processor TDP for the SR650 V4 — cross-reference before the chassis ships to avoid a disruptive field swap.
• The 10 lb mass requires careful handling during installation; the CPU socket retention clip must be inspected after seating to confirm the heatsink is fully locked — partial engagement is a common field error with heavy heatsinks and shows up as intermittent thermal throttling rather than an immediate fault.

The 4H47B03713 is the right call for SR650/A V4 nodes running high-core-count workloads in edge AI inference or dense virtualization stacks where CPU TDP headroom cannot be compromised by an undersized thermal solution.
