low frequency myslia 20 - 30 hz, inak to nefunguje.
Postavil a pouzil som zopar regulatorov a jedine co mi vadilo
bolo bzucanie ventilatora.

Zdravim osadenstvo,

mate niekto skusenosti ci sa daju otacky takehoto

ventilatora riadit PWM? Podla tohoto je vsetko v poriadku

A 2-wire fan is controlled by adjusting either the dc voltage or pulse width in low-frequency PWM. However, with only two wires, a tach signal is not readily available. This means that there is no indication as to how fast the fan is running—or indeed, if it is running at all. This form of speed control is open-loop.

Su tam nejaki specialni diablici, na ktorych si treba dat pozor?
