120 mm 24 V square fan for inverter cooling

This OEM Industries cooler is a SANYO 109R1224H1011 square fan measuring 120 mm across and 38 mm thick. It runs on 24 V at 0.25 A and uses a three-pin power connector. The unit is a fan-only assembly intended for inverter or industrial cooling applications.

Black frame with three-wire connector

The black square housing fits standard 120 mm mounting patterns while the 38 mm depth requires sufficient clearance behind the mounting surface. A three-wire lead provides power, ground and tachometer feedback for speed monitoring. No LED lighting is present, keeping the appearance neutral for server or embedded use.

Verify 24 V header and 38 mm depth before ordering

Check that your system supplies a 24 V fan header; a 12 V header will not drive this fan correctly. Confirm the mounting area can accommodate the 38 mm thickness and that the three-pin connector matches the board header pinout. Buyers needing PWM control or a different voltage should look elsewhere.

Questions about this item

What does the 3-pin connector mean for speed control on the 109R1224H1011?

The 3-pin connector supplies power and a tachometer signal so the motherboard can monitor RPM, but it lacks a PWM wire so speed is adjusted by varying the 24V voltage instead of a digital pulse-width signal.

Will the 120 mm by 38 mm frame fit my chassis fan mounts?

The fan uses a standard 120 mm square frame that is 38 mm thick, so it matches common 120 mm mounting holes; verify your case or heatsink has clearance for the 38 mm depth before installing.

How do I wire the three leads correctly on the 109R1224H1011?

Connect the red wire to 24V, the black wire to ground and the yellow wire to the motherboard tachometer header; reversing the red and black leads will prevent the fan from spinning and can damage the motor.
