SXDOOL 25mm DC5V 2507 Ultra-miniature Brushless Circuit Board Cooling Fan 2-wire case fan

Ultra-miniature 25 mm board cooler

This 25 mm square fan fits directly onto a circuit board or tight enclosure where a standard frame cannot. It runs from a 5 V or 12 V supply and draws only 0.15 A at 5 V or 0.06 A at 12 V. The two-wire lead ends in a simple terminal interface for quick soldering or header connection. Builders working on embedded boards, router mods or small-form-factor projects will appreciate the footprint.

Oil or sleeve bearing with 2-pin power

Two bearing variants exist in the same 2507 body: one uses an oil bearing rated at 26 dBA, the other a sleeve bearing at 27 dBA. Both spin at roughly ten thousand revolutions per minute and consume less than one watt. The red and black leads are polarity-marked, so incorrect wiring is unlikely. No PWM or tachometer wire is present, so speed control must come from voltage regulation.

Random terminal style ships as-is

The supplier notes that the terminal type on the lead is chosen at random unless a specific style is requested. This means the connector may or may not match a standard header pitch on your board. Keep a few crimp pins or a soldering iron handy to adapt the ends. No mounting screws, adapters or software are included in the package.
