Easiest Way To 12v The Fans!, Includes Instructions for 7 and 9 volt. Options

[Grim187]

i know a lot of you are still cutting the + wire on the fans and just wiring it to a 12v spot on the board, altho this dose work there is an easier way that doesn't require modifying the fans.

for a lesser fan speed cut the ground of both fans and run both ground wires to a power source (after doing the 12v fan mod).
for 7v ground to this point: Xenon, Zephyr/Falcon/Opus/Jasper
for 9v ground to this point: Xenon, Zeyphr/Falcon/Opus/Jasper

Xenon:

Bottom of the Board:
Yellow=12v Black=CPU Red=GPU

(If your Having Trouble Understanding Click the Picture)
OR
Top of the Board:
Bridge Black for CPU, Bridge Red For GPU.



Zephyr, Falcon, Opus & Jasper:
The Zephyr, Falcon, Opus and Jasper Board have the same voltage line to both fans
so it wont be possible to 12 or 7v just one fan w/o cutting the wires.

Bottom of the Board:

OR
Top of the Board:


Note: Sunon and Nidec Fans have Reversed Power Wires.



Trinity/Valhalla:
Bottom of the Board:

Red=5v, Yellow=Fan Speed Control.
Bridge for Full Speed.
Potentiometer for Controlled speed.



If you plan to use a potentiometer to manually adjust the fan speed here is one
that is close to the right strength and here is how it should be used.

The fan used was a stock 360 fan (of course, who knows if ONE manufacturer is used throughout). I know that I had an excellent connection on the bridge (I used to solder modchips on PS1s, so I'm used to finite soldering), so I don't think that this was the issue. I'd have to venture a guess that your third option was the issue. I didn't bother testing it out, as I knew the wire-cutting method worked.

Believe me, I'm not knocking the method outlined here...I just wanted others to know about the potential for less than perfect performance when doing this version of the 12V mod.
