I want to permanently* reduce speed of some molex case fans (2x 120, 1x 80). I have them connected on a single PSU wire in a queue one after the other.
I think that the best way would be to switch wires (12V for 5V) on the first molex which would change the whole queue to be powered by 5V and therefore reduce their speeds. I already did this on a one testing fan and old PSU (started up using paper clip on green and black wires) and it was working.
And finally to my question. Can I safely use it this way? I am mostly concerned about PSU, I don't want it to get damaged because draining 5V without 12V or something like that. I think it should not cause any problems but just to be safe I wanted to ask you guys since you know much more about computer hardware than I do.
* Better to say until I decide otherwise which won't happen sooner than in summer.
