Lenovo 4H47A82888 SR650 V3 2U Performance Heatsink

Lenovo 4H47A82888 SR650 V3 2U Performance Heatsink

Overview

The Lenovo 4H47A82888 is a 2U rack-form performance heatsink designed for the ThinkSystem SR650 V3 server platform. At 10 lb, this is a substantial thermal component — the kind of mass and fin density required to handle high-TDP processor configurations in dense 2U chassis where passive cooling headroom matters. If you're commissioning SR650 V3 nodes in a high-density compute row or a network video recorder stack, matching the correct heatsink to your processor TDP tier is non-negotiable: running an undersized cooler against a high-core-count Xeon is a thermal throttling problem waiting to happen.

Manufactured in Mexico and sourced factory-new through channel-direct distribution, the 4H47A82888 is a genuine Lenovo part — no grey-market, no parallel imports. It carries UNSPSC commodity code 43201538, consistent with server thermal/cooling components in enterprise procurement systems.

Key Features

• 2U Rack Form Factor: Engineered specifically for 2U chassis depth — the heatsink height and fin profile are sized to clear the SR650 V3's airflow baffle and adjacent DIMM slots. Do not attempt to substitute a 1U heatsink; clearance and retention clip geometry differ by chassis generation.
• 10 lb Solid Mass: The 10 lb weight reflects a full copper or copper-aluminum composite core with dense fin stacking — the thermal mass needed to absorb processor transient loads before airflow catches up. Lightweight heatsinks in this application class are a compromise; this one is not.
• Platform-Specific Engineering: Designed for the SR650 V3 server line, meaning retention bracket spacing, backplate compatibility, and fin orientation align with the SR650 V3's motherboard layout and fan wall. Cross-generational substitution (SR650 V2 vs. V3) is not recommended without verifying Lenovo's compatibility matrix.
• Factory-New Genuine Part: Procured through US channel-direct sourcing — factory-new condition, manufacturer warranty applies, no refurbished or pulled-from-service units.

Integration & Compatibility

The 4H47A82888 is specified for the Lenovo ThinkSystem SR650 V3 2U rack server. Before ordering, cross-reference your processor TDP and the SR650 V3 configuration guide to confirm this is the performance (vs. standard) heatsink tier required for your CPU selection. Lenovo's server and storage platform documentation segments heatsink SKUs by processor wattage band — installing the standard heatsink under a 205W+ processor voids thermal compliance. This part addresses the performance tier. Consult Lenovo's ServerProven or the SR650 V3 product guide for the definitive processor-to-heatsink pairing table before finalizing your data center infrastructure bill of materials.

Frequently Asked Questions

Q: What server is the Lenovo 4H47A82888 compatible with?

A: The 4H47A82888 is designed for the Lenovo ThinkSystem SR650 V3 2U rack server. It is not confirmed compatible with prior SR650 generations (V2 or V1) without verifying Lenovo's compatibility documentation.

Q: Why does a heatsink weigh 10 lb?

A: Performance-tier heatsinks for high-TDP server processors use dense copper or copper-aluminum fin stacks with substantial thermal mass. The 10 lb weight on the 4H47A82888 is consistent with a component engineered to handle processor TDPs in the 205W+ range where lightweight alternatives would result in thermal throttling.

Q: Is this the standard or performance heatsink for the SR650 V3?

A: The product name designates this as the performance heatsink for the SR650 V3. Lenovo segments SR650 V3 heatsinks by processor TDP tier — verify your CPU's wattage against Lenovo's SR650 V3 configuration guide to confirm this is the correct tier for your build.

Q: Is the 4H47A82888 a new or refurbished part?

A: The 4H47A82888 is sourced factory-new through channel-direct distribution — no refurbished, grey-market, or parallel import units.

Q: Where is the 4H47A82888 manufactured?

A: Country of origin is Mexico (MX), consistent with Lenovo's ThinkSystem hardware manufacturing supply chain.

The 4H47A82888 is one of those parts that looks like a line item until you're standing in front of a throttled SR650 V3 at 3 AM. At 10 lb, this performance heatsink is Lenovo's answer to high-TDP Xeon configurations in the SR650 V3 — the mass tells you everything about what it's designed to handle.

Technical Highlights:

• 2U Form Factor Specificity: The 2U rack designation is not just a size note — it defines fin height, retention geometry, and airflow lane alignment for the SR650 V3 chassis. Substituting a non-platform heatsink risks fouling the baffle or leaving processor die coverage incomplete.
• 10 lb Thermal Mass: In a server this dense, thermal mass buffers processor power spikes until the fan wall catches up. A lighter heatsink in this socket position is a throughput limiter under sustained compute load.
• Performance vs. Standard Tier: Lenovo deliberately separates heatsink SKUs by processor wattage band. The 4H47A82888 sits in the performance tier — if your SR650 V3 BOM includes a high-core-count or high-frequency Xeon, this is the correct SKU; the standard heatsink is not a safe substitute.

Deployment Considerations:

• Always cross-reference the SR650 V3 configuration guide before ordering — processor TDP determines which heatsink tier Lenovo requires, and ordering the wrong tier means a second shipment and a delayed rack commissioning.
• Watch for generational fit: the SR650 V3 retention bracket differs from the V2. Even if a prior-gen heatsink physically mounts, thermal interface contact and clip tension may not meet spec — use the platform-matched part.

The 4H47A82888 is the right call for SR650 V3 deployments running high-TDP processors in dense compute rows — HPC nodes, AI inference racks, or high-channel-count NVR server builds where sustained processor load is the operational baseline, not the exception.
