What screws to use for Noctua 1140mm

[Fester1]

I'm trying to install 3 Noctua NF-A14 case fans into Fractal R4 case. However, I'm completely confused on which screws to use:

1) Rubber screws that came with the fan
2) Metal screws that came with the fan
3) Metal screws that came with the Fractal R4

Any help would be appreciated. Total noob here.

Those are well-balanced fans, so you will probably not get any vibration if you use the standard metal screws...but I would try to use the rubber screws if they hold...I've had bad luck with them, I always pull too hard!!!

Thanks, I just went ahead and used the metal screws for now. If the vibration is that bad, then I'll switch.

I've got another problem now. I installed the fans, but they won't go back into the Fractal R4 case. Here's a pic:

why not?

edit: that sounded stupid...what problem are you running into?

Figured it out. The fans are not supposed to have the wires on the right, they're supposed to be installed so that they go through the middle section, in between the two fans.
