Replacement CPU GPU fan for X540 series laptops

This 4-pin 5V .5A cooling fan fits X540SA, VM520U, X540S, X540SC, X540LA, X540, X540L, F540 and related models. It uses a DC brushless motor for quiet heat dissipation. The metal housing matches the original mounting points when hole positions align. Designed for owners of these specific laptops who need a direct swap.

Practical limits of the 4-pin 5V .5A interface

The connector supplies only 5 volts at 0.5 amps, so the fan cannot exceed that power envelope. Speed control depends entirely on the laptop’s PWM implementation; some boards may not vary voltage smoothly. Cable length is fixed at the factory standard and cannot be extended without splicing. Polarity is locked by the keyed header, preventing reverse insertion.

Installation notes and common pitfalls

Remove the old fan first and compare screw holes and cable routing against the product photos before fitting. The 9-inch measurement is approximate; allow up to 1 cm variance from manual sizing. Misaligned mounting holes are the usual cause of fitment failure. No screws or thermal paste are included in the package.

Questions about this item

Which model number should I pick for my X540 series laptop?

The single version listed is B2RD4NB1401193; it fits X540SA, VM520U, X540S, X540SC, X540LA, X540LJ, X540YA, X540L, X540 and F540 models.

What does the 5V .5A rating mean once the fan is installed?

It draws 5 volts at 0.5 amps from the motherboard header, giving the DC brushless motor enough power for quiet, steady airflow.

How does the 4-pin connector limit what I can control?

The 4-pin PWM header lets the board vary fan speed automatically; without that header the fan would run at full speed constantly.
