Lenovo 4H47B08906 SR860 V4 STD Heatsink

Lenovo 4H47B08906 SR860 V4 Standard Heatsink

Overview

The Lenovo 4H47B08906 is the standard heatsink assembly designed for the ThinkSystem SR860 V4 server platform. Weighing 10.00 lb, this is a substantial thermal management component — the kind of mass that reflects the SR860 V4's high-density processor configurations, where sustained heat dissipation directly determines whether CPUs sustain boost clocks or throttle under load. If you are replacing a failed or damaged heatsink in an SR860 V4 chassis, or building out a new system that requires a discrete heatsink order, this is the factory-spec part.

Key Features

• Platform-Specific Fit: Engineered for the SR860 V4 chassis — using a non-spec heatsink in a high-core-count server risks thermal limits and voided service agreements. The 4H47B08906 is the correct part for this platform, eliminating guesswork on compatibility.
• 10.00 lb Construction: The weight reflects the copper and aluminum mass required to pull heat from enterprise-class processors at sustained workloads. Lighter aftermarket alternatives routinely underperform under prolonged CPU stress — this spec matters.
• Factory-New Genuine Part: Sourced as a factory-new component, not refurbished or pulled from decommissioned hardware. For server deployments where uptime is non-negotiable, starting with a genuine part is the baseline, not a premium.
• Manufactured in Mexico: Country of origin MX, relevant for procurement teams with supply chain documentation or trade compliance requirements.

Integration and Compatibility

The 4H47B08906 is designed for the Lenovo ThinkSystem SR860 V4. Before ordering, confirm your chassis generation — the SR860 V4 is distinct from prior SR860 generations, and heatsink assemblies are not universally interchangeable across server generations. Consult the Lenovo server catalog or your SR860 V4 documentation to verify the correct heatsink part number for your specific processor and thermal configuration. If your SR860 V4 is configured with high-TDP processors, verify whether the standard heatsink (this unit) or a performance heatsink variant is required — that determination depends on your CPU selection, not the chassis alone.

Frequently Asked Questions

Q: What server platform does the 4H47B08906 fit?

A: The 4H47B08906 is the standard heatsink for the Lenovo ThinkSystem SR860 V4 server platform. It is not confirmed compatible with other SR860 generations without independent verification.

Q: Is the 4H47B08906 new or refurbished?

A: This is a factory-new, genuine Lenovo part — not refurbished, not a pull from decommissioned hardware.

Q: What does the 4H47B08906 weigh?

A: The heatsink assembly weighs 10.00 lb.

Q: Where is the 4H47B08906 manufactured?

A: Country of origin is Mexico (MX).

Q: Do I need the standard or performance heatsink for my SR860 V4?

A: The correct heatsink variant depends on your processor TDP. Confirm the requirement in your SR860 V4 configuration guide or with Lenovo pre-sales before ordering.

The 4H47B08906 is the standard heatsink assembly for the ThinkSystem SR860 V4 — and the 10.00 lb weight is the first thing that tells you something about this platform. SR860 V4 configurations can support multiple high-core-count processors; that mass is the copper and aluminum doing actual thermal work, not packaging weight.

Technical Highlights:

• 10.00 lb Assembly: Substantial heatsink mass supports sustained thermal dissipation in high-density, multi-processor SR860 V4 configurations where CPU throttling under load is a real operational risk.
• Platform-Specific Design: Engineered to the SR860 V4 mechanical and airflow envelope — fit and airflow channeling are not interchangeable with prior SR860 generations.
• Factory-New Genuine Part: Sourced new, not pulled inventory — relevant when you need a clean service record and full manufacturer warranty eligibility on the host server.

Deployment Considerations:

• Verify your SR860 V4 processor TDP against Lenovo's heatsink selection matrix before ordering — standard versus performance heatsink variants are determined by CPU choice, not chassis model alone.
• Evidence for this part is limited to weight and origin data from distribution; for full thermal specification and installation torque requirements, reference the SR860 V4 maintenance manual directly before installation.

The 4H47B08906 is the right order for SR860 V4 deployments requiring a replacement or spare standard heatsink — most directly relevant to data center operators maintaining hot-spare inventory for high-availability compute clusters where unplanned downtime is not acceptable.
