Somehow these things are no longer available anywhere individually.

I was also upset because I wanted 4 individual ones because they only give the cables with which you can use the fans without a controller! I wanted to connect the fans directly to the mainboard and to a fan controller.

That's why I ordered 4 more last week. They were still in stock.
But my order was cancelled by Digitec because they were no longer available!

Now I'll have to order somewhere abroad!
