120 mm 12 V DC case fan

This 120 mm square axial fan runs on 12 VDC and delivers 120.1 CFM at 2900 RPM. It fits standard 120 mm mounting holes with a 38 mm frame depth and uses a three-wire lead with a locked-rotor sensor. The ball-bearing motor is rated for 70000 hours at 40 °C. It suits builders who need high airflow in a compact footprint.

44 dB(A) noise and 5.52 W draw

In normal operation the fan produces 44.0 dB(A) while drawing 5.52 W at 0.460 A. Static pressure reaches 0.354 in H2O (88.2 Pa) for effective heat-exchanger airflow. The voltage range spans 4 to 13.2 VDC, allowing speed control via PWM or voltage reduction. Operating temperature covers -10 to 60 °C.

38 mm thick frame

The 38 mm frame depth determines case compatibility; thinner 25 mm slots will not accept this fan. Buyers who need a slimmer profile should look for a 25 mm model. The plastic frame and blades keep weight at 0.564 lb. CE, CSA, UL and VDE approvals are included.

Questions about this item

How do I connect the three-wire lead to a motherboard header and which step do people miss?

Plug the 3-wire lead into a 12 V fan header; the third wire is the speed sensor and must sit on the sense pin or the BIOS will report 0 RPM.

What maintenance will this 120 mm ball-bearing fan need after long-term use?

The ball bearing is rated for 70000 hrs at 40 °C; no lubrication is required, but dust buildup on the plastic blades should be cleaned with compressed air to keep airflow near 120.1 CFM.

At what temperature does the fan hit its operating limit during sustained loads?

The rated range stops at 60 °C (140 °F); above that the 0.460 A motor may exceed its thermal design and the 44.0 dB(A) noise spec no longer applies.
