Lenovo 4H47B03712 SR650 V4/SR850 V4 2U STD Heatsink

Lenovo 4H47B03712 SR650 V4 / SR850 V4 2U Standard Heatsink

Overview

The Lenovo 4H47B03712 is the standard 2U heatsink designed for Lenovo ThinkSystem SR650 V4 and SR850 V4 rack servers. When a processor slot requires a dedicated thermal solution — whether you are populating a second CPU, replacing a damaged unit, or building out a new server configuration — this is the correct factory-matched part. At 10 lb, it is the full-size production heatsink, not a filler or low-profile variant, which matters when planning chassis weight and rail load ratings for your rack.

Sourced factory-new from distribution, the 4H47B03712 is a genuine Lenovo server component manufactured in Mexico (MX). UNSPSC commodity code 43201538 identifies it as a computer processor cooling component for procurement and inventory classification purposes.

Key Features

• Platform Fit — SR650 V4 and SR850 V4: Designed specifically for Lenovo's current-generation 2U rack platforms. Using the correct heatsink ensures proper TDP headroom and maintains thermal warranty coverage on the processor — substituting non-matched heatsinks on high-core-count Xeon configurations is a support risk you do not want to carry.
• 2U Standard Form Factor: The standard-height profile fits 2U chassis clearance without modification. If you are working in a high-density blade or 1U configuration, this is not the correct part — verify your chassis form factor before ordering.
• Factory-New, Genuine Component: Sourced direct from Lenovo's distribution channel. No refurbished, pulled, or grey-market units — important for servers running production workloads under active hardware support agreements.
• 10 lb Shipping Weight: Plan rack weight accordingly when populating both CPU sockets across multiple SR650 V4 or SR850 V4 nodes. Dual-socket configurations add approximately 20 lb in heatsinks alone across a single server unit.

Integration and Compatibility

The 4H47B03712 is validated for use in the Lenovo ThinkSystem server line, specifically the SR650 V4 and SR850 V4 platforms. Verify your server's processor TDP against Lenovo's configuration guide before installation — standard heatsinks are rated for standard TDP processors; high-TDP CPUs require the performance heatsink variant. If you are configuring a 2U rack server build from scratch, cross-reference the Lenovo ServerProven compatibility matrix to confirm CPU/heatsink pairing.

For data center thermal planning and server infrastructure builds, ensure your rack's airflow direction (front-to-rear) aligns with the SR650 V4/SR850 V4 chassis design. Heatsink installation requires standard Torx tooling — confirm your field kit before dispatching a technician.

Frequently Asked Questions

Q: Which servers is the 4H47B03712 compatible with?

A: The 4H47B03712 is the standard 2U heatsink for the Lenovo ThinkSystem SR650 V4 and SR850 V4 rack servers. It is not validated for earlier SR650/SR850 generations — verify your server model before ordering.

Q: What does the 2U standard designation mean — is there a performance heatsink variant?

A: The standard heatsink is designed for processors within the standard TDP envelope for the SR650 V4 and SR850 V4 platforms. High-TDP processor configurations typically require a separate performance heatsink. Check Lenovo's configuration guide for your specific CPU's heatsink requirement.

Q: Is the 4H47B03712 a new or refurbished part?

A: This is a factory-new, genuine Lenovo component sourced through distribution. It is not refurbished or pulled from a used system.

Q: What is the weight of the heatsink?

A: The 4H47B03712 has a shipping weight of 10 lb. Account for this when planning rack load ratings, especially in dual-socket configurations.

Q: Where is the 4H47B03712 manufactured?

A: Country of origin is Mexico (MX).

Karl Wilson

The 4H47B03712 is a straightforward but frequently mis-ordered part — the SR650 V4 and SR850 V4 both have a standard and a performance heatsink variant, and ordering the wrong one against a high-TDP processor is a thermal event waiting to happen. At 10 lb, this is the full production heatsink, not a placeholder, so it installs exactly as Lenovo intended for standard processor TDP configurations.

Technical Highlights:

• Platform Specificity: Validated for SR650 V4 and SR850 V4 only — earlier V3 and V2 chassis use different mounting interfaces and should not be cross-populated with this part.
• 2U Form Factor: The standard 2U height means full fin stack for airflow — adequate for standard TDP CPUs but do not attempt to run a high-TDP Xeon on this heatsink expecting stable thermals under sustained load.
• Genuine, Factory-New: Sourced new from distribution, which matters when the server is under an active Lenovo hardware support contract — third-party or pulled heatsinks can trigger support disputes on thermal-related failures.

Deployment Considerations:

• If you are populating a previously empty CPU socket on an SR650 V4 or SR850 V4, confirm the heatsink variant matches your processor's TDP rating against Lenovo's ServerProven documentation before installation — standard vs. performance is a real distinction, not a marketing tier.
• Watch: at 10 lb per heatsink, a fully populated dual-socket rack row adds meaningful cumulative weight — factor this into rail load and seismic bracing calculations for dense data center deployments.

This part is the right call when you need a genuine, platform-matched thermal solution for an SR650 V4 or SR850 V4 build or socket-population expansion in a production data center environment.
