Web\$\begingroup\$ This petervis links seem suspect -- the article claims the tach signal is in "PWM format", which is nonsense, and that the tach output is at TTL voltage level. The author may be confused between tach output, and PWM input to fan. (Not all fans have both, or indeed either, of PWM input and tach output.) Read answers below, and Intel … WebJul 21, 2024 · A PWM fan will have some minimum ‘starting’ drive before it will begin rotating. This is usually about 25%. Once it starts, it will continue to run with smaller PWM values, as small as 5%. With that out of the way, there’s a more important issue in your circuit: you shouldn’t drive the PWM pin with OUT. bin number in credit cardWebThe PWM pin accepts 5V input, and sources no more than 5mA, so it should be fine. Many fans should work with Arduino´s default PWM. The Norm says you have to use 25 kHz PWM frequency though, which is a bit tricky. See AKA's post in the Control PWM Fan Thread.
