| Oct 23, 2020 at 15:15 | comment | added | JackOfHearts | No, that's a good idea. I have another one but is it almost the same reference, it is just a little bigger. I will try to find another one and test it. | |

| Oct 23, 2020 at 15:05 | comment | added | JackOfHearts | I have checked the PWM, the one at the gate of the transistor and the one at the drain are as expected. | |

| Oct 23, 2020 at 14:53 | comment | added | Wesley Lee | Perhaps the "auto restart" function is preventing it from running via PWM? A lot of brushless fans will be better controlled via 4 pin PWM (which will also indicate that the are meant to be run in different speeds). In my experience a lot of these higher RPM fans aren't meant to be ran at lower speeds (won't even start at low PWM duty cycles). | |
