ARGB LIGHTING EFFECTS - The 120mm ARGB SickleFlow fan (16.7 million colours) features translucent blades, which diffuse light evenly across the fan(3-Pin ARGB), and is fully compatible with ARGB motherboards. UPGRADED BLADE DESIGN - The latest Air Balance fan blades are both larger and more curved than their predecessors and deliver even better air flow (62 CFM) and pressure (2.5 mmH2O). CASE & COOLER READY - Due to their hybrid blade design, SickleFlow fans are an excellent choice for cases with obstructed airflow (extra air pressure) or for CPU heatsinks and radiators that have widely spaced fins (or outdated fans). REINFORCED FRAME - The 120mm square housing has been updated with additional rib support which improves mechanical efficiency while dampening vibration and noise (8~27 dBA). NEW BEARING SEALANT – The rifle bearing features a two-tier sealing mechanism to protect against dust and leakage, thereby improving durability (160,000 MTTF) and outperforming competitors in its fan bearing class (650~1800 RPM).
