Thermal module Lenovo 5H40Z26567 – laptop cooling assembly, OEM replacement part

Thermal module Lenovo 5H40Z26567 – laptop cooling assembly, OEM replacement part is a direct-fit cooling component designed to restore thermal management in compatible Lenovo notebooks. This replacement thermal module reestablishes heat transfer from the CPU and GPU to the heat sink and exhaust vents, helping to maintain targeted operating temperatures and reduce the risk of thermal throttling. It is an OEM-compatible assembly intended for repair and service use to recover cooling performance and extend the useful life of internal components.

Advantages

The assembly provides stable and consistent heat dissipation by restoring the original heatpipe and heatsink path, enabling the notebook to run at designed performance levels. As an OEM-compatible part, it matches the original form factor and mounting points to simplify installation and minimize mechanical adjustments. Replacing a degraded or damaged thermal module reduces fan workload and can lower internal temperatures, which contributes to longer component life and more reliable system behavior.

Suitable for (tasks / use cases)

• Repairing Lenovo laptops with reduced cooling efficiency or overheating issues
• Service and maintenance tasks in workshops and authorized service centers
• Replacing damaged or corroded heatpipe and heatsink assemblies
• Restoring thermal performance after spill damage or mechanical shock

Key specifications

• Function: laptop thermal module (heatpipe and heatsink assembly) for CPU/GPU heat dissipation
• Compatibility: designed for specific Lenovo notebook models (verify model compatibility before purchase)
• Material characteristics: copper/aluminum heatpipe and fin-stack construction for efficient thermal transfer
• Form factor: OEM-compatible replacement with original mounting points and connectors
• Purpose: repair/service component to restore factory thermal pathway and cooling performance

How to use

Before installation, power down the notebook, disconnect the battery and follow anti-static precautions. Remove the bottom cover and any obstructing components to access the existing thermal module, noting screw locations and connector positions. Carefully detach the old thermal module from the CPU/GPU and clean the mating surfaces using appropriate isopropyl alcohol and lint-free cloth. Apply a thin, even layer of thermal interface compound to the processor surfaces, then position the replacement thermal module and secure it with the original screws in the correct sequence. Reassemble the notebook, reconnect the battery and perform a controlled power-up to verify fan operation and stable temperature readings.

Usage recommendations

Verify compatibility with your specific Lenovo notebook model before purchase. Use high-quality thermal compound and proper torque on fastening screws to ensure ideal contact. If uncertain about disassembly or reassembly procedures, seek professional service to avoid damage to internal components.
