The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...

Diodes Inc.has announced the introduction of a pair of all-in-one single-phase 12 V fan motor drivers for low to medium voltage brushless DC fan control in consumer, home appliance, industrial and ...

Well, I'm using Noctua fans which are damned well made. I was originally going with Redux fans, but I found them too noisy, so I'm going to return them in favour of NF-S12A PWM which come with a 1:2 ...
