High-pressure 120 mm PWM case fan

The Delta AFB1212HHE-PWM is a 120 mm case fan built for systems that need strong static pressure. Dual ball bearings and a 4-pin PWM connector allow automatic speed control tied to workload. It suits builders who want reliable airflow through dense heatsinks or restrictive mesh panels. Buyers needing silent operation above all else may prefer a lower-speed alternative.

Thermals noise and power draw

At full speed the fan spins at 2900 RPM, moving 120.07 CFM with a maximum air pressure of 9 mmH2O while producing 44 dBA. Typical input power is 4.8 W at 0.4 A, rising to 8.4 W at 0.7 A maximum across the 10.8–13.2 VDC operating range. The airflow-to-noise ratio is 2.73:1, reflecting its focus on pressure over quietness.

PWM control and bearing life

The 4-pin PWM connection lets the motherboard reduce speed during light loads, cutting noise when full pressure is not required. Dual ball bearings are rated for 70,000 hours at 40 °C with 15–65 % RH, roughly 16 years at 12 hours daily use. No extra mounting hardware or software utilities are included in the package.

Questions about this item

How do I install the AFB1212HHE-PWM and what step is often missed?

Mount the 120 x 120 x 38 mm frame with four screws, then plug the 4-pin PWM connector into the motherboard header; the step often missed is enabling PWM control in BIOS so the fan can vary from idle to 2900 RPM.

What maintenance or replacement will this fan need later?

The dual ball bearing is rated for 70000 hours at 40 °C and 15 - 65 % RH; after that the bearing will need replacement, and no lubrication or other service is required before then.

What limit appears first during sustained high-load operation?

At full speed the fan draws 0.7 A (8.4 W) and produces 44 dBA; the noise level and the 9 mmH2O pressure ceiling are the first limits you will encounter under continuous load.
