Unique-Bargains 120x120x25mm 7 Vanes DC 12V 0.18A Case Fan

Compact 120 mm case fan for standard chassis cooling

This 120 x 120 x 25 mm fan fits the common mounting pattern found in most PC cases and power-supply housings. It runs on a DC 12 V supply drawing 0.18 A and uses a seven-vane impeller to move air through tight spaces. The two-wire lead is 27 cm long, giving enough reach for typical motherboard or controller headers. Builders looking for a straightforward replacement or supplementary airflow will find the dimensions familiar.

Voltage must match the 12 V rail

The fan is rated exclusively for DC 12 V operation at 0.18 A; connecting it to a 24 V source will damage the motor. Verify that your power supply, fan controller or motherboard header provides a 12 V output before wiring. The two-wire design carries power only, so speed reporting or PWM control is not available. Buyers who need variable-speed operation or a 24 V fan should select a different model.

Simple screw mounting with 105 mm hole centres

Four mounting holes spaced 105 mm centre-to-centre accept standard 4.3 mm diameter screws, aligning with the vast majority of 120 mm fan grilles. The 27 cm two-wire cable reaches most headers without extension, though routing behind a motherboard tray may require a tie-wrap. No specialised tools are needed beyond a Phillips screwdriver. Ensure the airflow direction matches your chassis layout before tightening the screws.
