Product Details Features/
The kit has three 120×120×25 mm fans in black.
They are stackable / daisy‑chainable, meaning you connect the fans in series, so instead of pulling wires from each fan separately, you use a single PWM cable + single ARGB line.
There is a built‑in switch in the controller to reverse airflow direction (forward ↔ reverse) without having to flip or change the fan physically. 
The fans use shock‑absorbing pads in the corners to reduce vibration / noise. 
The lighting / frame style includes an “infinity mirror” effect around the fan frame, which gives a border of mirror‑like lighting reflections. 
Performance / Technical Specs
Fan Speed: ~ 800 to 2000 RPM ±10%.
Airflow: up to 75 CFM approx. (some listings give ~75 CFM ±10%) for this kit. 
Static Pressure: ~ 2.05 mm H₂O at maximum speed. 
Noise Level: about ~ 30 dBA under PWM / at high speeds. Some listings say ~29.2 dBA. 
Power / Current Draw: rated current ~0.16 A (±0.04 A) max. Power about ~1.92 W per fan. 
Bearing Type: Hydro bearing. 
Number of Blades: 7 blades per fan. 
Lifespan: ~ 50,000 hours usage at ~25°C. 
Fan Blades etc: Because of the reversible & stackable design these fans are usable both for airflow (case intake/exhaust) and radiator use.
