Replacement CPU Fan for ThinkPad T420S

This replacement CPU cooling fan fits the Lenovo ThinkPad T420S and carries the AVC BATA0507R5U 004 part reference. It is intended for owners whose original fan has become noisy or stopped spinning. The unit ships new and each piece is tested before dispatch.

DC 5 V 0.45 A power specification

The fan operates at 5 volts and draws 0.45 amperes, matching the electrical requirement of the original ThinkPad T420S cooling assembly. Verifying this voltage and current rating against the old fan is the single check that confirms compatibility before purchase.

Tested for continuous operation

Every fan is individually tested to confirm 100 percent function before shipping, ensuring it sustains airflow during extended workloads rather than only at startup. A nine-month warranty backs the expected reliability under constant thermal load.
