• Repairing Lenovo laptops and mobile workstations with a matching cooling assembly
• Replacing a noisy, failing or clogged fan to restore proper airflow
• Maintenance tasks during cleaning, thermal paste replacement or component upgrades

Key specifications

• Function: active cooling for CPU/GPU areas
• Form factor: laptop/workstation internal fan assembly designed for specific chassis
• Connector type: motherboard-compatible multi-pin fan connector (matching original design)
• Power: low-voltage DC fan compatible with laptop power delivery
• Material: plastic housing with integrated fan blades and mounting points
• Noise profile: designed for balanced acoustic output under typical load

How to use

Installation requires disassembly of the laptop or workstation to access the internal cooling assembly. Power the device off, disconnect the battery if possible, and follow the manufacturer service manual or a trusted repair guide for step-by-step access to the fan area. Remove screws and any heatpipe or shroud securing the original fan, disconnect the fan cable from the motherboard, and replace it with the new unit ensuring correct seating of mounting points and secure connector engagement. Reassemble the device, reconnect power sources and verify fan operation in the BIOS or operating system monitoring tool before normal use.

Recommendations

Perform replacement in a clean, static-safe workspace and use appropriate tools. Inspect ventilation channels and heat-sink surfaces, and consider renewing thermal interface material when the fan is replaced to ensure optimal thermal transfer. If uncertain about compatibility or installation steps, consult official service documentation or a qualified technician.
