how to connect the fans to a raspbery 4

@RIKKO14 all of mine are connected directly to the pi

Ok thanks, I tested with a light, the thumbnail of the fans should be up for mine.

@RIKKO14 sorry what is thumbnail of fan?

a priori, the editing on the 1st photo is good because air comes out, not with the editing of the 1st photo

Thumbnail = the sticker on the fan

whenever I unplug my pi and plug it back in the fan will go crazy and make a loud noise. What I do is unplug it and plug it back in multiple times until it goes back to normal. Anyone know why?
