Ventoinha de arrefecimento Lenovo System FAN L 81MV Modelo 5F10S13875 para sistemas Lenovo, peça OEM de substituição

Lenovo System FAN L 81MV is a replacement cooling fan designed for compatible Lenovo desktop and workstation systems. As an OEM-equivalent service part, this fan delivers directed airflow to internal heat-generating components such as the CPU, chipset and power modules. It helps stabilise operating temperatures under load and supports reliable system operation during sustained use.

Advantages

The fan provides focused cooling with a compact form factor compatible with designated Lenovo chassis layouts. It is built to meet the airflow and thermal dissipation characteristics required for the supported systems, offering a straightforward swap-in option for worn or failed original fans. Using a proper system cooling fan reduces the risk of thermal throttling and contributes to prolonged component life.

Suitable for

• Replacing a failing or noisy system cooling fan in compatible Lenovo desktops or workstations
• Repair and maintenance tasks where original cooling performance needs restoring
• Service-part inventories for IT departments and repair centres supporting Lenovo systems

Key specifications

• Function: system cooling fan for internal chassis airflow
• Form factor: compact fan assembly designed for Lenovo chassis mounting
• Airflow: engineered to provide targeted airflow to CPU, chipset and power areas
• Connector type: system fan power connector compatible with Lenovo mainboard headers
• Operating environment: designed for typical desktop/workstation thermal ranges
• Compliance: manufactured to match OEM performance and integration requirements

How to use

Power down the system, disconnect it from mains and open the chassis following the manufacturer’s service instructions. Remove the existing fan assembly by disconnecting the power cable and any mounting screws or clips, then install the Lenovo System FAN L 81MV in the same orientation, secure it with the original mounting hardware and reconnect the fan cable to the appropriate header. Reassemble the chassis, restore power and verify fan operation and system temperatures in the BIOS or with monitoring software.

Recommendations

Perform installation in a static-free environment using appropriate tools. Ensure intake and exhaust vents are clear of dust and obstructions. If replacing a noisy or failing fan, compare connector and mounting alignment before final assembly to avoid cable strain or improper seating.
