40 mm Sleeve-Bearing Fans for 24 V Systems

This pack contains ten 40 mm square fans designed for 24 V power rails. Each unit draws 0.1 A through a two-pin connector and uses a sleeve bearing. The fans suit builders who need multiple low-profile coolers for tight enclosures or replacement parts for legacy hardware.

Thermals Noise and Power Draw

At 24 V the fans run on a modest 0.1 A current, keeping power draw low in normal operation. Sleeve bearings typically produce a gentle airflow sound that stays quiet at modest speeds. The simple two-wire design means speed is fixed unless an external controller is added.

Upgrade Path and Compatibility

These fans replace worn 40 mm sleeve-bearing units in industrial gear, small form-factor PCs or embedded boards that already use a 24 V two-pin header. They are not suited for builders who need PWM speed control, larger frame sizes or higher static pressure for dense heatsinks.

Questions about this item

How do I install the 40mm fan using the 2-pin connector?

Align the 2-pin connector with the 24V header on your board, press it straight on, and route the wires so the 40*10mm frame sits flat; the step most people miss is checking polarity before powering up.

What maintenance will the sleeve bearing need over time?

The sleeve bearing runs dry eventually; when noise rises or speed falls, swap in another unit from the 10-piece pack.

What limit appears first when the fan runs continuously at 24V 0.1A?

Continuous operation at the rated 24V 0.1A will wear the sleeve bearing lubricant first, leading to audible rumble and reduced rpm.
