FD1340D015 40x40x20mm 40mm 4CM DC13V 3Pin Dual Ball Bearing HighSpeed Cooling Fan, Replacement Cooling Fan for Power Supply, Small Industrial Equipment Heat Dissipation

FD1340D015 is a compact 40×40×20 mm DC cooling fan rated for DC13V input. It comes with a standard 3pin connector that outputs tachometer signal, allowing host hardware to monitor realtime fan rotational speed. Builtin dual ball bearing minimizes mechanical friction, supports longduration continuous operation and delivers better durability compared to sleeve bearing fans. Its highspeed rotational performance produces substantial airflow to exhaust internal heat efficiently. The small 40 mm footprint fits tight confined spaces inside power supplies and other miniature devices. Predrilled mounting holes enable quick and secure installation. This unit serves as an ideal dropin replacement fan for power supply repair, small chassis cooling, embedded systems and various industrial heatdissipation projects. It maintains stable performance under sustained working conditions for equipment maintenance and refurbishment applications.
