Slevflow ASQ 120 Spectra S (Infinity Sides, Dual Middle Ring) is a 120 mm PWM‑controlled case fan with hydraulic bearing, designed to boost airflow while offering eye‑catching ARGB lighting. It spins at roughly 800–1800 RPM, moves around 65.5 CFM of air with a static pressure of 2.15 mm H₂O — strong enough for case ventilation or radiator cooling. It also includes anti‑vibration pads for quieter operation and supports 5V ARGB + 4‑pin PWM with daisy‑chain capability, letting you easily sync lighting and fan speed with other fans.
