Lenovo 4H47A85857 Thinksystem SR665 V3 2U Standard HSK

Lenovo 4H47A85857 ThinkSystem SR665 V3 2U Standard Heatsink

Overview

The Lenovo 4H47A85857 is a standard heatsink designed for the ThinkSystem SR665 V3 platform in its 2U rack configuration. Weighing 10 lb, this heatsink is a direct thermal management component for processor cooling in SR665 V3 deployments — the correct part to specify when replacing a failed heatsink or completing a processor installation that shipped without one. Sourced factory-new from distribution; no grey-market, no parallel imports.

Compatibility

Designed for the Lenovo ThinkSystem SR665 V3 in 2U rack form factor. Verify your SR665 V3 chassis revision and processor TDP requirements against Lenovo's compatibility matrix before ordering — the SR665 V3 platform offers both standard and high-performance heatsink variants, and processor TDP determines which is required. This part number corresponds to the standard (non-high-performance) heatsink; if your processor SKU requires the performance heatsink, confirm the correct part before deployment. Check Lenovo's rack server documentation for processor-to-heatsink pairing by TDP class.
