How to install Lenovo ThinkSystem SR650 GPU Thermal Kit

• Power down the SR650 server and disconnect all power sources. Remove the side panel to access the internal components and prepare the system for hardware modification.
• Identify suitable PCIe slots for your GPUs and verify there is adequate clearance for full-length cards alongside the new cooling hardware. Clear any obstructions and organize cables to avoid interference with the mounting components.
• Install the two full-length card holders into the designated PCIe slots or mounting points as instructed by Lenovo’s service documentation. Ensure they are firmly seated and aligned to support the GPUs securely.
• Attach the two low-profile heatsinks to the GPUs according to the kit’s mounting pattern. The heatsinks should sit flush with the card surfaces, providing optimal contact for effective heat transfer without obstructing adjacent components.
• Mount the air duct in the appropriate position to channel airflow toward the GPUs. Route cables as needed to prevent airflow disruption. Reconnect power and verify that the GPUs are seated correctly and the cooling channel is unobstructed.
• Close the server, reattach the side panel, reconnect power, and boot the system. Enter the BIOS/UEFI or management software to confirm GPU presence and monitor temperatures under typical workloads. Run a burn-in or benchmark test to validate thermal performance and ensure there is no throttling during sustained operation.
