Replacement Cooling Fan for Positivo Sim Laptops

This new cooling fan replaces the original MF60070V1-C140-A99 part in Positivo Sim 2450m and 2560m models. It is intended for owners of those specific laptops who need to restore factory cooling performance. Buyers with different laptop models or chassis designs cannot use this component.

Direct-Fit Compatibility and Part Verification

The fan carries part number 49R-3NH4CU-1401 and matches the NH4CU43 specification for the listed Positivo Sim series. It fits only those exact model numbers; any variation in chassis or connector will prevent installation. Buyers who need a universal cooler or a different form factor must look elsewhere.

Single-Fan Package and Compatibility Responsibility

The package contains one tested fan unit without mounting hardware or thermal material. Correct fitment depends on verifying the part number against the original before ordering. Buyers who cannot confirm the exact MPN or who require a complete cooling assembly with heatsink will not be served by this item.

Questions about this item

Will the NH4CU43 fan fit my Positivo Sim 2450m without modifying the chassis?

The fan is built for the Positivo Sim 2450m and 2560m series; matching the NH4CU43 part number to your service manual confirms a direct fit.

How can I verify the MF60070V1-C140-A99 spins correctly after I install it?

Power on the laptop and listen for steady airflow from the vent; the BIOS hardware monitor should report a stable RPM reading for the CPU fan.

Does the package include mounting screws or thermal pads, or just the 49R-3NH4CU-1401 fan unit?

The box contains only the 1 x Fan; screws, thermal pads and any cable adapters must be sourced separately.
