Help Mounting Case outtake fan

[Aster22]

Hey Tom's
I just removed my liquid cooling cause i'm pretty sure it broke and wanted to replace it with a hyper 212 evo. But when i removed the my old liquid cooler(Asetek 510LC) i found that i had no way to mount my outtake fan on my Haf 912 there's no place to screw it in. The screws just go right though the holes with nothing to screw into.Do i need bolts? Do i need a new fan?
Any help will me much appreciated thanks.

take one of the bolts and screw it into the fan. if it holds then you have to put the fan on top or on the bottom of the case wholes and screw the bolt into the fan. most case fans are silver and screw into the fan and hold the fan down by the fan plastic shroud.

I don't have the bolts could i find such small bolts and the screws that came with the fan are smaller then the hole im afraid that if all i do is put bolts in the fan won't hold in place.

these would go from the top outside of the case into the fans to hold them.
look at the case user guild that online to help you.
if not them look for local shop that has m4 screws

all your looking for is a bolt that go from the top of the case pass the fan bottom by a little and then you want to put a screw on the end of the nut to hold the fan.
