Compact, highly flexible controller for 4-pin PWM fans Works as a manual speed reducer or in tandem with the automatic motherboard fan control: achieve truly quiet operation, even with high-speed ...

If you don’t already have one, you’ll probably want a fan, too. This circuit is meant for a 12V fan. I use this controller ... boost the PWM signal up to 5V for the fan. I use the 74AHCT125 to perform ...

connecting the YELLOW cable to PIN 4, BLACK on 6 and BLUE on pin 8: doing so, you will have to use GPIO 14 to control the speed of your fan. I measured the tension on the NOCTUA PWM pin (blue cable) ...

Device that supplies 5 pwm signals, and gets 5 tacho signals. When a tacho is not ok ,than the controller ... (FAN-FAULT) that asserts low when the fan runs at a speed below the predefined minimum RPM ...

2-wire fans 3-wire fans 4-wire fans. The methods of fan control to be discussed here include: no fan control on/off control linear (continuous dc) control low-frequency pulse-width modulation (PWM) ...

I would like to interface the XTR115 to a standard 3.3V or 5V MCU pin with PWM(isolation required). can any one provide working circuitary? See parts 4 and 5 of a recent blog series we published on ...
