Hello
I have a fan connected. Ground and power supply connected, PWM connected to 9 pin in Arduino Uno. In the settings in SimHub, the volume to the maximum, according to the instructions, etc. When I disconnect the pwm, the fan rotates at 100%, and when I connect the PWM it runs gently, slowly. No testing, maximum etc., no fan response. Please help, the fan is SilentiumPC Zephyr 120MM PWM
Hi !Â
When you say ground connected, the power supply ground is correctly connected to the Arduino too ? it must go to both the fan gnd and the Arduino gnd. At first sight that is my best bet.Â
Also make sure to use the pwm fan entry, not the simple pwm, even if both are called "pwm", the fan specific pwm option uses a 25khz frequency required for this purpose
grounding is coverage here and here. As for the pwm fan, how to check?
I've detailled the process here : https://www.simhubdash.com/community-2/postid/820/
Let me know 😀
I do everything as described in the manual, I have already done it before, but the fan does not respond. I know that he won't stop to 0, but that's not a problem for me. I just want his speed to increase.
Could you send a picture of your wiring ? If you can't make the fan goes faster and you have followed conscientiously the process I linked. It makes me think about an issue on this side.

Pictures are but are waiting for approval
Hi
I do have exactly the same problem. Fan is working at 100% speed when the pin 9 is not connected. When it's connected it runs slowly no matter the parameters set at SimHub.Â
Did you find a way to solve this issue ?
