High-speed 120mm case fan
The Delta AFC1212DE-PWM is a single 120 x 120 x 38mm case fan built for systems that demand maximum airflow. It spins at 3900 RPM and moves 148.34 CFM through a standard 4-pin PWM header. A TAC sensor provides real-time speed feedback for precise control.
Builders who need extreme cooling headroom
This fan suits servers, workstations or overclocked rigs where thermal margin outweighs acoustic comfort. At 51 dBA the noise level is prominent, so it is not a fit for quiet living-room PCs, noise-sensitive studios or any build that prioritises low decibel levels over raw airflow.
38mm frame thickness
The 38mm depth is the critical specification; verify that your chassis or heatsink mounting points accommodate this profile before purchase. Standard thinner brackets will not accept the frame, making the dimension the single factor that decides whether the part can be installed.

Questions about this item
What does the box contain for the AFC1212DE-PWM, and do I need to purchase mounting screws separately?
The package includes one 120 x 120 x 38mm fan with a 4-pin PWM connector and TAC sensor. Mounting screws are not included and must be sourced separately.
How do I decide between different versions or capacities of this Delta 120mm case fan?
This model is offered as a single configuration: 3900 RPM, 148.34 CFM airflow, and 51 dBA noise at 38mm thickness. No alternative speed or capacity variants are available for this MPN.
What does the 3900 RPM headline figure deliver once the fan is installed in a case?
At full speed it moves 148.34 CFM of air through a standard 120mm mount while producing 51 dBA. The 4-pin PWM control and TAC sensor allow the motherboard to lower speed and noise when full flow is not needed.
