I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

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.

However, PWM fans offer much more precise control over the exact speed of the fan. As mentioned above, both DC and PWM fans can vary their speed. However, a PWM fan can be controlled more precisely.

The only problem is that the Noctua uses PWM, so there’s no governing it with a just potentiometer. ... classic hacks, Microcontrollers Tagged arduino, fan, solder smoke, soldering fan. Search.

Getting down to Arduino basics, PWM output is possible in an Arduino (Uno) on its digital I/O pins 3, 5, 6, 9, 10, and 11. Here the “analogWrite” function can be used to set the PWM duty cycle. To ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

7) Custom designed PWM IC with SCD – Noctua’s custom-designed NE-FD1 is a next-generation PWM fan driver IC that integrates Smooth Commutation Drive (SCD) technology for quieter operation and ...

Today we have with us a nice selection of fans from BitFenix. We have the 120mm and 140mm variants of the BitFenix Spectre Pro PWM series. In addition to that… ...
