Query: No screws, box was open..

They might work well I’m not sure, I opened my box with these fans and my power supply and there were no screws and the box for the fans was open and the little screw driver was jabbed into my power supply box.. I did hook one up and it kicked on.. but none of my case screws fit the large holes so I’ll have to wait and find screws I guess..
