Changes

A: The PWM 4010 fan for NASPi uses the yellow wire for PWM signal transmission, while most regular PWM fans typically use the blue wire for this signal. Please refer to the below photo of the fan port interface definition of X-C1 adapter:<br>red cable = 5V<br>black cable = GND<br>yellow cable = for PWM signal<br>If you encounter such issues, please check if this wiring difference is the cause.<p><a href="/File:X-C1-fan-Port.png" class="image" title="X-C1 Fan"><img alt="X-C1 Fan" src="/images/thumb/4/48/X-C1-fan-Port.png/500px-X-C1-fan-Port.png" decoding="async" width="500" height="309" srcset="/images/thumb/4/48/X-C1-fan-Port.png/750px-X-C1-fan-Port.png 1.5x, /images/thumb/4/48/X-C1-fan-Port.png/1000px-X-C1-fan-Port.png 2x" data-file-width="1233" data-file-height="763"></a></p>
