## Summary description

Replacement cooling fan and heatsink assembly Lenovo 5H40W36703 for compatible Lenovo laptops. This factory-design cooling module combines a fan and heat sink to remove heat from CPU/GPU components, restoring thermal performance and preventing overheating, throttling, and unexpected shutdowns. Suitable for repair, maintenance, and refurbishment of laptops original parts require matching part number.

## Long description

Replacement cooling fan and heatsink Lenovo 5H40W36703 is a factory-design cooling assembly intended for compatible Lenovo laptops. This module integrates a centrifugal fan with a dedicated heat sink to extract heat from central processing and graphics components, restoring proper thermal management to prevent thermal throttling and unexpected shutdowns. The assembly is designed for direct replacement of worn or damaged cooling parts and for maintenance or refurbishment tasks where original-form cooling performance is required.
Advantages
The cooling assembly combines an efficient fan and a precision-formed heatsink to ensure heat is transferred away from the CPU/GPU and expelled through the laptop chassis. It restores designed airflow pathways and contact pressure at the heat pipes and cooling surfaces, reducing operating temperatures and stabilizing performance under load. Using a like-for-like cooling module helps maintain system noise characteristics and preserves fitment and mounting points for straightforward installation.
Suitable for
 Repair of Lenovo laptops with failing or noisy cooling fans
 Maintenance and refurbishment to restore thermal performance
 Replacement after liquid damage or physical impact affecting the cooler
 Upkeep to prevent CPU/GPU throttling during sustained workloads
Key specifications
 Integrated fan and heatsink design for direct thermal coupling to CPU/GPU
 Heat pipe(s) and fin stack geometry matched to the laptop chassis airflow
 Form factor and mounting points compatible with designated Lenovo laptop models
 Thermal interface contact surfaces pre-shaped for factory fitment
 Electrical connector type matching laptop system fan header
How to use
Power down the laptop, disconnect the battery and external power, and open the service panel according to the laptop manufacturer’s maintenance instructions. Remove the existing cooling assembly by unscrewing the mounting fasteners and disconnecting the fan cable from the motherboard. Fit the replacement cooling fan and heatsink into place, align mounting points, secure screws to specified torque values if available, and reconnect the fan cable. Reapply or replace thermal interface material to the CPU/GPU as required before final assembly, then test the system to confirm proper fan operation and temperature behavior under load.
Usage recommendations
Use compatible thermal paste and follow manufacturer torque specifications for mounting screws. Avoid touching the heatsink contact surfaces with bare hands to prevent contamination. After installation, run a controlled stress test and monitor system temperatures and fan RPM to verify restored cooling performance.
