I am using the Nactua NF-A9x14 PWM fans with a radiator in my Ncase M1. Where can I get screws that accommodate 14mm fans instead of the typical 25mm fan?
Step 1.
Determine the thread and screw size. Enough guides online (
example)
Step 2.
Find replacement screws either the right size or ones you can shorten. If you know what screw size and thread it has, you can visit the hardware store.
Step 3.
If your replacement screws are too long or you can't find replacements and want to sacrifice your original screws (I recommend finding replacements), you can shorten them properly with this kind of screw/wire stripper pliers:
Usually they come in Metric (M3) or Imperial (6-32), rarely both. Ideally use a matching nut, which you wind for enough down the screw so it can go in the pliers and after stripping you can remove it, possibly fixing a thread issue caused by cutting it.
