## Summary description

Replacement cooling fan and heatsink assembly for Lenovo systems, model 5H40W36701. Designed to remove heat from internal components and maintain safe operating temperatures. Intended for use as an OEM-compatible service part for repairs or upgrades. Helps restore proper cooling performance and reduce overheating, improving system stability and longevity.

## Long description

This replacement cooling fan and heatsink assembly is designed for Lenovo systems as an OEM-compatible service part. It replaces the original cooling module to remove heat from CPU and nearby components, helping maintain safe operating temperatures and restore proper thermal management after a failure or during an upgrade. The assembly includes the fan, heatsink fins and heat pipes in a matched configuration to direct heat away from internal components and toward the airflow path.
Advantages
The assembly provides targeted heat dissipation with an integrated fan and heatsink configuration that fits Lenovo system mounting points and cooling channels. It restores airflow efficiency and helps reduce thermal throttling by improving heat transfer from the processor and surrounding components. The unit is intended for straightforward replacement of a failed or underperforming cooling module and supports consistent fan speed control via the system firmware.
Suitable for
Repairing a Lenovo laptop or small form-factor system with a failed or noisy cooling module
Replacing a worn fan to restore original cooling performance
Upgrading a damaged heatsink assembly after liquid damage or impact
Key specifications
Function: active cooling with integrated heatsink and blower fan
Cooling elements: metal heatsink fins and heat pipe sections for heat transfer
Fan type: system blower fan designed for directed airflow inside chassis
Mounting: compatible with Lenovo system mounting brackets and screw positions
Interface: connects to the system fan header for power and RPM control
Intended thermal role: CPU and adjacent component heat dissipation
How to use
Power off the system, disconnect external power and remove the battery if applicable before beginning. Open the chassis according to the manufacturer service instructions, detach the existing cooling module by disconnecting the fan electrical connector and removing mounting screws, and carefully lift out the old assembly. Clean residual thermal material from the processor and heatsink contact surfaces, apply a thin, even layer of compatible thermal compound to the processor, then position the replacement assembly in place and secure it with the original screws. Reconnect the fan cable to the system header, reassemble the chassis, and power on the system to verify fan operation and temperature behavior in firmware or monitoring software.
Usage recommendations
Use genuine or quality thermal compound and follow anti-static precautions during installation. Verify compatibility with the specific Lenovo model before purchase by checking chassis layout and connector type. After installation, monitor system temperatures under load to confirm the replacement restores expected cooling performance and that fan noise and RPM behavior are within normal ranges.
