Probably not worth asking but: is it possible to fix a seized case fan?
These things are pretty disposable so I doubt I'm going to get any kind of positive response but one of my 120mm case fans (from EZDIY-FAB) seems to have seized up. It's got a lot of drag when I spin it by hand but it's still receiving power because the white LED ring is still operating. I'm not sure what caused this to happen but when I went looking for a replacement fan of a similar type they no longer seem to exist, being replaced across the board with ARGB fans. I'm not against ARGB, exactly, but this particular motherboard doesn't have any RGB headers and any of the remaining single-color LED fans on the market are also 3-pin while my fan is a 4-pin PWM fan.
So at this point, if I want to have a uniform look with illuminated case fans that are also PWM, it seems I have to either install a standalone RGB controller (and have to maintain a remote just to color all my fans white) or go with non-speed controlled fans unless I can fix this fan. Is that doable?
