Odroid XU4 making a sharp noise

Unread post by sergiomafra » Thu May 09, 2019 1:17 am

As shown on video, there is a sharp noise besides the fan noise. When the fan stops, the sharp noise continues. And it is irritating haha

Does anyone know its origin and how to stop it?

Can you carefully disconnect the fan connector with tweezers to find a noise source.
Some fans didn't rotate with a low PWM output level and you have to adjust the PWM level slightly higher.
