Laptop-ventilator-koellichaam Lenovo 01AY475 — koelmodule voor Lenovo-laptops

Replacement laptop fan heatsink Lenovo 01AY475 is a cooling assembly designed for compatible Lenovo notebooks. This component consists of a heat pipe system and a fan unit intended to transfer heat away from the CPU and GPU areas, restore effective thermal management, and reduce the risk of thermal throttling. It is supplied as an original-design part intended for repair or maintenance tasks where the existing cooling system is noisy, underperforming, or damaged.

Advantages

The heatsink and fan assembly provides targeted heat dissipation for processor and graphics components, helping maintain stable operating temperatures during typical workloads. Using a direct-fit replacement restores contact with heat sources and improves airflow compared with worn or clogged units. The assembly is manufactured to match the original mechanical layout, which supports straightforward installation and reliable alignment with vents and mounting points.

Suitable for

• Repairing laptops with reduced cooling performance or excessive fan noise
• Replacing damaged or bent fins, broken fans, or leaking thermal interfaces
• Preventive maintenance to restore factory-level thermal behaviour
• Work involving rebuilding or refurbishing compatible Lenovo notebook models

Key specifications

• Function: combined fan and heatsink assembly for laptop thermal management
• Cooling method: heat pipe conduction with blower fan to expel hot air
• Compatibility: designed for specific Lenovo notebook thermal modules (verify model fit before purchase)
• Materials: metal heat pipes and fin stack with plastic fan housing
• Mounting: screw-mounted bracket and connector matching original laptop layout

How to use

Before installation, power down the laptop, disconnect the battery and external power, and ground yourself to prevent electrostatic discharge. Open the service access panels following the manufacturer’s service manual, remove the old heatsink and fan assembly by unscrewing the mounting hardware and detaching the cooling connector from the motherboard. Clean residual thermal compound from the CPU/GPU surfaces using isopropyl alcohol and lint-free cloth. Apply a thin, even layer of fresh thermal compound to the processor surfaces, position the replacement heatsink assembly so mounting holes align, and fasten screws in a cross pattern to the specified torque if provided. Reconnect the fan cable to the board, reassemble the laptop, reconnect power, and verify fan operation and temperature behaviour during an initial boot and light workload.

Recommendations

Verify physical compatibility with your laptop model and consult the service manual for disassembly instructions. Use appropriate thermal paste and avoid over-tightening screws. If unsure about installation, consider professional service to ensure correct fit and to prevent motherboard or connector damage.
