Arctic P12 PWM PST 120mm PWM Fan with Cable Spliiter - 5 Pack in Black

Computer case Fan 12 cm 1350 RPM 53 cfm Fluid Dynamic Bearing (FDB) Pulse-width modulation (PWM) support Black 5 pc(s) 4-Pin PWM fan with standard case Long Service Life The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life Perfect Case Fan Regulation with PWM The PWM function allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling and minimizes the noise level. PWM Sharing Technology (PST) Lowers Noise If you want to improve the cooling efficiency of your computer you get several case fans working in parallel (since it takes 10 fans to double the noise level). But what does it help if they don't work together? The PST assures that all of your fans listen to one control signal. E.g. you share the CPU Cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary In
