This 5 V 0.50 A four-pin cooling fan is a direct replacement part for the NS85B12-16L17 model. It is intended for laptop owners who need to restore original airflow after a bearing failure or noise issue. The unit ships new and individually tested before dispatch.

Fits Laptops Using the NS85B12-16L17 Fan

Installation requires a compatible motherboard header and the physical mounting points used by the original cooler. The four-pin connector enables PWM speed control so the system can regulate fan speed automatically. No additional wiring or adapter cables are included in the package.

Steady Cooling Under Continuous Load

The 0.50 A rating indicates the current draw during sustained operation rather than a brief spin-up peak. This allows the thermal solution to maintain consistent RPM while the processor remains under heavy load. Buyers needing higher airflow or a different voltage spec should verify their part number before ordering.
