The HAVN H18 2-pack is a 180 mm PWM fan that combines high cooling performance with low noise generation. With up to 1300 rpm, it generates 279.71 m³/h air flow at 2.19 mm H2O static pressure and remains pleasantly quiet at 35 dB(A). Corrugated fan blades provide even airflow and reduce turbulence - ideal for radiators and mesh fronts.
