Okinos, 5 Pack, 120mm PWM Case Fans – 4-Pin Silent PC Fans, 1500 RPM High Airflow 67CFM, Low-Noise 28 dBA, Quiet Stealth Mode, Anti-Shock Pads, PWM Sharing w/ 1-to-3 Splitter Cable, Hurricane Series

【9 Extended Arc Blades】By adding 10% length of the pc fans arc through precise calculation, thus generated greater airflow (67.19 CFM), and ensured sufficient heat dissipation to extend the service life of internal component parts;
【Better Cable Management through Splitter】Each Fan Splitter includes 1*4-pin interface for speed signal transmission between PWM Fans and MOBO, the other 2 interfaces only with 3-pin connectors to prevent simultaneous signal transmissions, which may cause the fans to operate abnormally;
【Trio-Segmented Frame Design】8 inner corners of the 120mm case fan frame adopted Trio Segmented Frame Design, which effectively expanded the intake/exhaust area and increased additional 5% of total air volume;
【Advance Pillar Frame】4 Pillar directly penetrated through both sides of the case fan which provided resistence that can reduce the impact when fan running at extreme points on P/Q curve. hence prevent potential rattle noise, keep fans quiet;
【Reinforcement Bar Design】Rebar frame strengthened the overall stability of the fan, ensured that pc fans can perform highly closed to optimized P/Q curve, and also extended the life of the fan itself;
【8 Anti-shock pads】8 anti-shock pads effectively reduce vibration, as a result fan operate quietly at 27.5 dB(A)
【Package】(1) Hurricane Series 120mm PWM PC Fans x5；(2) 1 to 3 Fan Splitter x2；(3) Fan Screws x20
