80x80x25mm DC 12V Brushless CPU Cooling Fan, 2-Wire Power Lead, 0.25A Axial Case Fan for PC Heatsinks, DIY Enclosures, 3D Printer Electronics, Router/PSU Ventilation

H·HUN 80 mm brushless DC cooling fan for electronics thermal management. Standard 80 x 80 x 25 mm frame, 12 V DC, 0.25 A. The two-wire lead is terminated in a 2-pin connector: red to +12 V, black to ground.

The frame is 80 x 80 mm and 25 mm thick, with mounting holes on the standard 71.5 mm pitch. The holes are 4.5 mm in diameter and take M4 screws, so the fan drops into any standard 80 mm fan position in a PC case, heatsink shroud or project enclosure.

Two wires, power only. Red to +12 V DC, black to 0 V. At 12 V the rated current is 0.25 A, roughly 3 W. Size the supply for the total of all fans on it, with headroom for startup. Observe polarity: reversing it may stop the fan running and can damage the internal driver.

This is a 2-wire fan, so there is no tachometer (RPM sense) output and no PWM control input. To run it slower, reduce the supply voltage or use a DC fan controller, and check that it still starts reliably at the setting you choose.
