Lenovo 4M27A60832 ST650 V2V3 Performance Fan Kit

Lenovo 4M27A60832 ST650 V2/V3 Performance Fan Kit

Overview

The Lenovo 4M27A60832 is a factory-new performance fan kit designed for ThinkSystem tower servers running thermally demanding workloads. If you're pushing a ST650 V2 or V3 with high-core-count processors, dense memory configurations, or multiple expansion cards, the stock cooling may not deliver the headroom you need — this kit is the OEM-specified path to increased airflow without modifying the chassis or voiding the system warranty. The 4M27A60832 drops in as a direct replacement or upgrade within the existing fan bay, maintaining full compatibility with the server's IPMI fan-speed management and thermal control firmware.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST650 V2 and ST650 V3 tower servers. Do not install in ST550, ST558, or other ThinkSystem tower variants — fan bay geometry and connector pinouts differ by chassis generation. Verify your server's machine type before ordering. This kit is a Lenovo field-installable option (FIO), meaning it is intended for installation during initial system build or as a post-sale upgrade by a qualified technician.

Installation Notes

The kit weighs 1.25 lb and measures 5.90 x 5.90 x 6.25 in — plan bay clearance accordingly if adjacent PCIe cards or cable runs are present. Standard tool-less fan bay retention applies on ST650 platforms; no additional hardware required beyond what is included. Power the system down and discharge static before handling. Fan direction is fixed — confirm airflow orientation matches your rack's front-to-rear or side-exhaust thermal design before seating the unit.
