Two 140 mm ARGB fans with magnetic dome bearings

This dual pack supplies two white 140 mm case fans that use magnetic dome bearings for low friction and long life. Each unit runs from 330 to 1700 RPM and moves up to 95.5 CFM with a static pressure of 3.46 mm-H2O. Noise spans 10 to 36 dBA, and a zero RPM mode stops the blades entirely at light loads. Eight addressable LEDs per fan connect through a single +5 V ARGB header.

Suits builders who want simplified cabling

Daisy-chain wiring lets multiple fans share one 4-pin PWM and one +5 V ARGB connector, reducing cable clutter inside the case. The high static pressure and AirGuide vanes make the pair effective on radiators or dense heatsinks. Buyers whose cases only accept thinner frames or who lack a 5 V ARGB header will need a different solution.

140 mm frame with 25 mm thickness

The fans measure 140 mm square by 25 mm thick, so they fit standard 140 mm mounting points on cases and radiators. Verify that your chassis has clearance for this thickness before ordering.
