I finished building my first desktop a couple weeks ago so I still am every new to this... Anyway I ordered additional fans to install into my NZXT 410 Phantom. The problem is that although the fans came with screws, the fans weren't threaded. Apparently this is the standard and I'm supposed to screw in the screws to create threads. I tried doing it with a screw driver but the screw ended up getting stuck and I think I was beginning to strip the screw... (not sure if I had the right screwdriver head lol) What's everyone's experience with case fan installation? I'm thinking that maybe I should use a power drill... Also I'm adding two 120mm CM sickeflow fans, a 120mm NZXT fan, and a 140mm NZXT fan if that's relevant. Thanks!
