[SOLVED] How to install Noctua fans at the front of a 750D case?

[Komirai]

Took the screws out of the previous fans to put in the Noctua fans but the screws have no thread at the end and doesn´t feel secure at all. The super short screws that come with the Noctua fans don´t fit through the case holes so trying to use the ones that came with the case. I´m so confused first time changing fans, they both 140mm.

Any help or advice?
