120 mm AC 230 V case fan

This 120 by 120 by 25 mm fan runs directly from 220 to 240 V mains power without a separate supply. It draws 0.08 or 0.07 A at 16 or 14 W and spins at 2400 or 2900 RPM to move 64 to 75 CFM. The unit weighs 330 g and is rated for continuous industrial and medical equipment cooling.

Pre-installation checks

Verify that your chassis has a 120 mm mounting pattern and that the 25 mm thickness clears surrounding components. Confirm the local mains voltage falls within the 220 to 240 V range and that wiring can handle the rated current. Noise at the higher speed reaches 42 dB, so consider acoustic requirements for the intended location.

Replaces lower-airflow AC fans

The 65 to 70 CFM rating suits upgrades from older 120 mm AC units delivering less flow at similar voltage. The jump is worthwhile when equipment temperatures exceed safe limits or when a failed fan must be swapped for a direct drop-in with identical mounting holes and voltage.

Questions about this item

What comes in the box with the UF12B23BTHSize fan and do I need to buy mounting screws or a power cable separately?

The package contains the 120x120x25 mm fan unit only. Mounting screws and a mains lead are not included and must be sourced separately.

The specs list two power ratings — 16 W and 14 W — so which one should I expect in my system?

Power draw is 16 W at 2400 RPM and 14 W at 2900 RPM; the actual figure depends on the mains frequency at your location.

The headline airflow shows 65-70 CFM — what does that mean once the fan is installed in a case?

In free air the fan delivers 64-75 CFM at 38-42 dB; inside a case with filters and grilles the effective airflow will be lower.
