Cooler Master SickleFlow 140 ARGB (MFX-B4DN-14NPA-R1)

ARGB LIGHTING EFFECTS - The 140mm 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 ai... morer flow (67 CFM) and pressure (2.2 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cases with obstructed airflow (extra air pressure) or for CPU heatsinks and radiators that have widely spaced fins (or outdated fans).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 140mm square housing has been updated with additional rib support which improves mechanical efficiency while dampening vibration and noise (10~27 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 (650~1400 RPM).

ARGB Lighting: Signature cooling performance with an ARGB 3-Pin design: a perfect choice for all of the users wanting lighting effects that are individually customizable. New Blade Design: Revised curve blade design to improve airflow and air pressure. A refreshed blade for improved lighting. Enhanced Fan Frame: Enhanced frame structure, reducing... moreturbulent flow noise increase efficiency. Sealed Bearing Structure: Sealed and secured fan bearing, preventing dust and lubricating oil leakage while increasing the fan’s operation stability and life span. PWM Fan Control: Dynamically adjust the speed between 650 rpm to 1,400 rpm, minimizing noise or maximizing airflow.
