I'm new to this forum, I've to tell you I live in Uruguay (South America) my native lenguage is spanish and I'm a car mechanic, so I have some knowledge about electric things.
I've finally found a bunch of people that are into "quiet", I don't get why people buy screaming fans, I don't know if they compete to win the "Louder PC Contest". I'm into performance, but I want it quiet as well, my PC is in my bedroom 2 steps far away from my bed.
I used to have a P3 1ghz, my father burnt it, so I came back and I'm with my K6 266 @ 337
Now to the topic:
I've seen that many of you made that switching 5v/off/12v, I prefer 7v/off/12v, and I noticed some of you were having troubles.
I've made my own baybus (that's how it's called), really cheap, but it gets time to do it and some soldering skills (nothing anyone can't get, just practice).
What I've used was only this
and here is the pic of my pc with the baybus
and used this to conect the fans, takes just 2 seconds to plug the fans to it
