Laptop cooling fan Lenovo model 5F10Z58241 DC5V compatible with Toshiba C-267C-1

Replacement laptop cooling fan designed by Lenovo for internal thermal management. This DC 5V cooling fan is compatible with Toshiba C-267C-1 and intended as a direct replacement to restore proper airflow, reduce operating temperature, and prevent performance throttling or unexpected shutdowns caused by an aging or noisy fan. It fits into the laptop's cooling assembly and connects to the motherboard using the original connector type to provide steady, quiet cooling during normal use.

Advantages

The fan delivers consistent airflow at low voltage to maintain stable CPU and GPU temperatures. Its construction aims to reduce vibration and operational noise compared with worn-out units, while maintaining compatibility with the laptop's cooling ductwork and mounting points. The part is designed for straightforward replacement, improving system reliability and extending the service life of the laptop by restoring effective heat dissipation.

Suitable for

• Repairing laptops that exhibit overheating, frequent fan noise, or thermal throttling
• Replacing a failed or intermittent internal cooling fan in compatible models
• Routine maintenance to restore original cooling performance
• Service operations in workshops and home repair projects involving compatible Lenovo/Toshiba models

Key specifications

• Rated voltage: DC 5V
• Form factor: internal laptop cooling fan designed for specific chassis mounting
• Connection: motherboard-compatible multi-pin connector (original connector type)
• Functionality: axial blower fan for targeted heat dissipation from CPU/GPU area
• Operational characteristics: balanced blade design for reduced vibration and lower audible noise

How to use

Power down the laptop, disconnect it from mains and remove the battery if applicable. Access the internal cooling assembly by removing the appropriate bottom cover or service panel according to the laptop’s service manual. Disconnect the old fan from the motherboard connector and remove any screws or clips that secure it. Install the replacement fan into the original position, secure it with the same fasteners, and reconnect the fan cable to the motherboard. Reassemble the laptop, restore power, and verify fan operation and system temperature under load.

Recommendations

Use ESD precautions when handling internal components. Ensure the replacement fan is installed in the correct orientation and that vents and heatsinks are free of dust. After installation, monitor system temperatures and fan behavior during initial use to confirm correct operation.
