Laptop CPU Cooling Fan Replacement, 4-Wire PWM DC 5V 0.50A Cooler Fan Compatible with NS85B10-17M13 DC28000LGD0 DC28000DBD0 NS85B10-16k23, Notebook & Small Server Internal Cooling Fan

This replacement internal cooling fan is a direct OEM substitute for the original fan marked NS85B10-17M13, DC28000LGD0, DC28000DBD0 and NS85B10-16k23, designed to resolve overheating, loud rattling, stuck fan and shutdown issues on your laptop or small server.

Adopting standard 4-wire PWM wire harness, the fan realizes real-time speed regulation linked with CPU temperature. It runs at low speed under light load for quiet daily use and boosts airflow automatically during gaming, rendering or heavy computing to quickly dissipate heat and prevent thermal throttling.

Strictly following original factory parameters, it operates at DC 5V input and 0.50A rated current, consistent with the power supply requirement of your devices motherboard. The precisely molded fan frame and blade structure fit the original installation position without modification, and the connector is identical to the stock plug for plug-and-play installation.

Built with wear-resistant bearing and high-strength plastic housing, the cooling fan delivers stable airflow with reduced vibration and noise. Each unit is fully inspected for rotation balance, voltage stability and connector tightness before delivery to guarantee consistent cooling performance.

Suitable for notebook CPU/GPU heat dissipation and mini embedded server cooling modules. It is a cost-effective repair part to restore your devices original thermal performance, extending laptop service life for office work, design creation and continuous server operation.
