OEM Industries DFS551205ML0T CPU cooler 4 Pin 5V .5A

Replacement fan for select Ideapad models

The OEM Industries DFS551205ML0T is a direct-replacement CPU cooling fan built for the Ideapad Y460, Y460A, Y460N and Y460C. It draws .5 A at 5 V through a standard four-pin connector so the motherboard can regulate speed. The two-tone housing and ball-bearing motor are sized to fit the original chassis without modification. It is not for builders needing a universal desktop cooler or a higher-flow unit for overclocking.

Sustained thermal behaviour

Ball-bearing construction keeps friction stable over long sessions, so acoustic output and rotational speed remain consistent when the system runs under continuous load. The four-wire PWM interface lets the firmware taper voltage as temperatures settle, preventing the voltage spikes that can occur with three-wire designs. No LED lighting means no extra current draw during extended use. It is not for users who want RGB illumination or software-controlled lighting effects.

Upgrade context

This part replaces a worn or noisy factory fan in the listed Ideapad models when the original bearing fails or airflow drops below spec. The jump is worth it when core temperatures climb under normal workloads or the stock unit develops a rattle that cleaning cannot fix. It is not for owners of other laptop series or desktop sockets where the mounting holes, connector pinout or voltage rail differ.
