    I purchased the original fan for the x86 at the udoo shop. It arrived today and right upon installation i realized something strange: it turns on as soon as the connector is attached - even if the OS (win 10) is shut down. And it keeps on running at full power no matter what. I have tried adjusting the thermal settings in the BIOS, but nothing seems to change this behaviour. I had to disconnect the fan since I couldn't find a way to shut it down. Any thoughts??? Tks!!!

    Tks for the tip, but this was the very first thing I tried. No luck. I am running v 1.03. I reset all settings back to factory defaults and that didn't correct the problem. Fan is still turning on even with the OS fully powered down (Udoo led amber).

    It is a 3 wire connection isn't it? Perhaps 2 wires are changed? Check the pdf manual for details.

    Yes, 3 wires. This is the fan sold at the Udoo shop, so I doubt there is an issue with wires being reversed or something like it. It seems more like a board issue as even with the OS shut down power is being sent to the fan.
    Is it possible to ask for a replacement board??
