SKU CH-34S1-3MXAF

A 120 mm square, 25 mm deep DC 24 V case fan with a 7-vane brushless motor and 34 cm cable for standard chassis mounting

  • DC 24V power suits industrial and server builds
  • 120 mm square frame fits standard case mounts
  • 7-vane impeller with fluid dynamic bearing runs quietly
  • 34 cm cable reaches most motherboard headers
  • 126 g lightweight design eases installation in tight spaces

24 V DC Case Fan for PC Cooling

This 120 mm square frame fan runs on a 24 V DC brushless motor and uses a seven-vane impeller to move air through a chassis. It is built for builders who need a standard-thickness cooler that fits common mounting points. The 34 cm two-pin lead connects directly to compatible motherboard headers.

Thermals Noise and Power Draw

The brushless motor and fluid-dynamic bearing keep operating noise low while delivering steady airflow at the rated 24 V. A 126 g net weight reflects a compact rotor that spins up quickly without adding vibration to the case. Power consumption stays within the limits of a standard 24 V fan header.

Standard 120 mm Mounting Pattern

Four 4 mm mounting holes spaced for the 120 mm square footprint let the fan serve as intake or exhaust in any orientation. Buyers who need PWM speed control or a three- or four-pin connector should look elsewhere because this unit only offers a fixed-speed two-pin interface.

Questions about this item

How do I install the 120mm fan and what is the common mistake with the 4mm mounting holes?

Mount the fan using the four 4mm screw holes on the 120mm frame; the step often missed is checking screw length so threads do not bottom out against the motor housing.

Which part will need replacement first on this 24V brushless fan?

The fluid-dynamic bearing is the wear item; once it degrades the fan develops noise or vibration and the whole unit must be swapped.

What limits continuous operation of the 34cm cable 24V fan under sustained load?

The 24V DC input and brushless motor set the thermal ceiling; if case airflow cannot remove the motor's waste heat, temperature rise will throttle speed or stop the fan.
