Hi! The case I modded about a year ago which serves as my main system, has 2 fans on the top, these came with the case and are not regular fans (the do not have the regular casing or design, it´s hard to explain without dismantling the whole thing to take picks off. The point is that because of this it´s rather hard to replace the whole thing (and prob not needed aniway). So my problem is, the leds still light up but the fans no longer turn, is this to do with the current trend on cases that bring fan speed controllers? meaning, aren´t these, essentially, voltage controllers? I.E. the less voltage the less they turn? could this in the long run essentially screw the fans up? and if so, could fixing this be as simple as, removing the little motor from another fan and replacing the one in these? Thanks!
