From the shop's description

ADDA AD0912UX-A7BGL DC Fan 12V 0.5A 90x90x25mm (USED LIKE NEW) The ADDA AD0912UX-A7BGL presents itself with compact clarity: a square frame, neat edges, a sense of purposeful engineering. The molding of the plastic casing feels firm and consistent, its surfaces bearing the even texture of a quality injection-molded part. From the front, you observe the blades poised in their resting state, evenly spaced, showing the balance and symmetry one expects in a precision cooling device. Even at rest, it suggests readiness an engineered tool waiting to spin. Once energized, the rotor begins to turn, gradually accelerating into a steady, confident spin. The sound evolves from a soft whisper into a calm, steady hum. The blades slice through the air, drawing or pushing it with an assured rhythm. The motion feels fluid; there is no jitter or stalling, only a consistent sweep. The airflow becomes tactile you can sense its current, a subtle but sure breeze that confirms its purpose. In quiet surroundings, the hum is perceptible but not intrusive. Installed in a system, the fan blends into the background until you pay attention. It doesn’t demand notice; it simply performs. When it stops, you realize how much you took it for granted the airflow diminishes, the ambient temperature shifts, the silence deepens. The form, even then, retains dignity: its structure intact, its blades unbent, its frame solid. It feels like a silent guardian of thermal balance unassuming, reliable, ever-ready to steady internal temperatures without calling attention to itself. Features: Smooth, stable blade rotation with minimal vibration. Quiet operation under typical loads. Balanced design to reduce wobble. Speed sensing (tachometer / feedback signal). PWM / control signal compatibility (4-wire interface). Robust frame construction for long-term use.
