  • 25 mm thickness suits tight spaces
  • Plastic frame keeps weight low

140mm USB case fan

The SXDOOL 14025 is a 140mm case fan designed for computer chassis cooling. It draws power from a standard USB interface, making it convenient for desktop users who want simple airflow without motherboard headers. The unit uses a double ball bearing for durability.

Plastic frame with 25mm thickness

The fan measures 140mm by 140mm by 25mm and features a plastic frame. It operates on a 5V USB connection with a two-wire design. This configuration suits general case ventilation but lacks PWM speed control or high static pressure for dense radiators.

USB power interface

The defining specification is the USB power interface, which limits the fan to 5V operation. Builders needing 12V PWM control, higher RPM ranges, or motherboard fan-header management should look elsewhere.

Questions about this item

Will the 140 mm USB fan fit in a case designed for 120 mm mounts?

The fan measures 140 mm by 140 mm by 25 mm, so it requires 140 mm mounting holes and will not align with standard 120 mm screw patterns.

How can I confirm the double ball bearing is running smoothly after I plug it in?

Listen for a steady, low hum without rattling; the double ball bearing design should deliver consistent rotation and minimal vibration at 5 V USB power.

Does the package include a USB cable or must I supply my own?

The fan has a built-in USB connector with two lines, so no separate cable is needed — just plug it directly into any 5 V USB port.
