Pulse-width modulation (PWM) is a modulation process or technique used in most communication systems for encoding the amplitude of a signal right into a pulse width or duration of another signal, usually a carrier signal, for transmission. But Scythe has not been available in the US for a while now, so hard to find. so as long as boht your Arduino and fans are using same power source you will have no problems. Unfortunately motherboards are moving to 4 pin PWM fan control while the best fans are mostly 3 pin. NZXT Aer RGB fans are designed to integrate seamlessly with our popular HUE+ LED controller. Depending on performance, I might want to add a condition for the fan speed to be increased when the AC is being used. So it can be best to pay attention to where the majority of your dust builds up. 5HP to 2HP motors with the ability to fine tune the speed while maintaining torque. The motherboard has 1 PWM fan header for the CPU, and two voltage controlled ones for the case. But the cases I have my eye on (Corsair Carbide 200r, Fractal Design Define R5) do not list in their specs if their case fans are 3 or 4-pin connectors. by: Al Williams and not much benefit but it would be worth trying it if you want the practice. a lot of newer board especially from asus have software to control any kind of fan from the OS Very often when designing some stuff I need a square wave signal generator with variable pulse width and frequency to control power MOSFETS. The sense pin is used to relay the rotation  Non-PWM fans can still have their speed adjusted by the mobo or a dedicated fan controller. 140mm Case Fans 6. 2CFM,DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes PWM Fan Intel LGA1151 AMD AM4 12cm Blue LED Heatsink Gaming Desktop PC De-Vibration,Deepcool MINI CPU cooler Double Heatpipe Radiator for Intel LGA 775/115x for AMD 754/940 Noctua NF-F12 PWM Cooling Fan It's worth noting that both fans do have the low noise adapter installed and are running about ~1200 RPM give or take.
