4028 is running the wrong way?
I have installed this fan from RatRig, used the red and the black wire and the blue for pwm control. When I start using my printer (V-Core 3.1 with an Octopus V1.1) I noticed that the fan turns the wrong way so the air blows out at the top. Is there a solution to make it turn the other side, other than flipping the fan..?
And can the yellow wire be used for anything?

Dumb question, but did you install the fan in the right orientation?
Posting a picture would be helpful

Yes, with the sticker facing upwards.
wrong way ^^
Sticker indicates the direction the air goes to

But if I twist it, than the protection of the fan will be inside
All fans I used in pc, printer etc have de enclose with sticker at the outside. Strange..
check the outside of the fan
there should be arrows
Sticker is always on the "Blow" side and not on "Suck" side

This is the way, same for computer fan. The „closed“ side is where the air goes. You can print a fan shroud
