Módulo térmico com ventoinha Lenovo 5H40T02803 — conjunto de arrefecimento de substituição para sistemas Lenovo compatíveis

This Lenovo thermal module with fan is a replacement cooling assembly designed for compatible Lenovo laptops and small form-factor systems. The module integrates an active fan and a heat-sink interface to dissipate heat from processors and other hot components, helping to maintain stable operating temperatures and reduce thermal throttling. Intended for repair or upgrade of system cooling, it installs in place of the original unit using existing mounting points and cooling interfaces.

Advantages

The assembly delivers targeted airflow across heat-generating components and provides consistent thermal conductivity via a dedicated heat-sink interface. Its compact design matches the original form factor for straightforward installation, while the fan provides active cooling to stabilize performance under sustained load. Using a compatible replacement helps restore thermal management, mitigate overheating, and extend the operational lifespan of internal components when installed correctly.

Suitable for

• Repairing a malfunctioning or noisy cooling system in compatible Lenovo laptops
• Replacing a damaged or worn-out fan and heat-sink assembly
• Upgrading thermal components during system maintenance or refurbishment
• Maintaining stable performance in systems prone to thermal throttling

Key specifications

• Cooling type: active fan with integrated heat sink
• Form factor: compact module designed to match original equipment mounting points
• Function: dissipates heat from CPU/GPU and nearby components to maintain operational temperatures
• Interface: airflow channeling and thermal contact surfaces for direct heat transfer
• Compatibility: intended for use in compatible Lenovo laptop and small form-factor systems

How to use

Power down the system, disconnect power sources and remove the battery if applicable before beginning installation. Access the internal compartment following the device service manual and locate the existing cooling assembly. Remove securing screws and disconnect fan cables, then extract the old module. Position the replacement module in the same orientation, ensure thermal contact surfaces align with the CPU/GPU, reconnect the fan cable, and fasten screws to the original torque specifications. Reassemble the device and power on to verify fan operation and system temperature stability.

Recommendations

Use approved thermal compound where the service guide specifies, avoid touching thermal contact surfaces with bare hands, and confirm compatibility with your specific Lenovo model before purchase or installation. Perform periodic cleaning of air intakes and fan blades to sustain airflow and cooling efficiency.
