High-speed 120 mm PWM case fan

The Delta FFB1212EH-PWM is a 120 mm case fan with a 25 mm thickness and a dual ball bearing. It runs at 4000 RPM and delivers 150.33 CFM of airflow at a rated 56.4 dBA. The 4-pin PWM connector allows automatic speed control from the motherboard.

4000 RPM airflow and static pressure

The single specification that decides fit is the 4000 RPM speed combined with 12.43 mmH2O maximum static pressure. This pairing moves 150.33 CFM through restrictive radiators or dense mesh, but it also produces the quoted 56.4 dBA noise level. Builders who need that pressure headroom accept the sound; those who do not will find the fan louder than necessary.

Suited for high-restriction cooling.

This fan suits water-cooling radiators, heatsinks with tight fin stacks, or chassis with restricted intake paths where static pressure matters more than quiet operation. It is not for builders who prioritise low noise in open-air cases, nor for systems that cannot supply the 12 VDC rail current the motor draws at full speed.

Questions about this item

How much airflow does the 150.33 CFM rating actually deliver inside a case?

The fan moves up to 150.33 CFM at 4000 RPM, with a peak of 190 CFM available when the PWM curve demands maximum cooling.

What does the 4-pin PWM connector control and what voltage range does it operate on?

The 4-pin PWM connector provides speed control and monitoring; the fan runs on 12 VDC with an operating range of 7 to 13.2 VDC.

Will the 25 mm thickness fit standard 120 mm mounting points in my chassis?

Yes, the frame measures 120 x 120 x 25 mm, matching the common 120 mm mounting pattern used in most cases.
