Fan on Nano

Hello everyone,

Looking for some guidance here. I got a fan for nano, actually two of them - one 10mm and one 5mm in height. The thing is - for both of the fans if I plug the 4-pin connector into the fan port, it does not spin up. Only when I am starting to pressing the connector down and have it angled slightly, the fan starts but as soon as I press the connector down a couple of mm more, it stops.

I got the second fan, thinking it was a fan/cable issue but with the second fan, I have exactly the same behavior.

Anyone have seen this?


Not sure about this, but looks like contact issue. For 4-pin connector, the design can be found in reference schematic in DLC. You may need to check the fan datasheet to make sure the pins connection.
