That's the screw that came with it, but it does not even fit in there and even if it did, there is no threading inside those holes and it obviously won't reach the other hole that would be against the case. And if you're thinking about going in from inside the case, those holes are not nearly big enough for these thick screws. And the screws that were inside the case attached to the old fans are long thin ones but as it turns out actually not long enough to reach through both of these holes and have enough length left to actually go into the case.
I'm really confused now.
Case is Corsair 750D.
