Lenovo System Cabinet Fan Option Kit

The Lenovo 4F17A12350 is a two-fan option kit designed for Lenovo ThinkSystem SR630 servers, models 7X01 and 7X02. By replacing or supplementing the original fans, it keeps critical components such as processors, memory, and storage bays within safe temperature limits.

Both fans work in tandem to maintain a steady airflow through the chassis. This consistent cooling is especially valuable when the server handles virtualization clusters, database workloads, or real-time analytics that push hardware to its limits. By preventing hotspots and thermal throttling, the kit helps the system deliver predictable performance during peak demand.

Installation is straightforward. Each fan slides into the designated bay, snapping onto existing power and control connectors. There is no need for extra cabling, firmware updates, or software configuration, so maintenance windows remain short and uncomplicated.

IT teams running dense rack environments, branch offices with limited cooling infrastructure, or labs that rely on continuous uptime will find this kit practical. It serves as an immediate upgrade for systems already running warm and as a ready-to-use spare that can be swapped in during scheduled maintenance or unexpected fan failure.

Highlights:

• Kit includes two fans engineered for Lenovo ThinkSystem SR630 servers, models 7X01 and 7X02
• Improves airflow to maintain stable internal temperatures during heavy workloads
• Tool-less installation into the server’s existing fan bays
• No software or firmware changes required for operation
• Helps prevent thermal throttling and supports consistent server performance
