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
for 9v ground to this point: Xenon
, Zeyphr/Falcon/Opus/JasperXenon:Bottom of the Board:
Yellow=12v Black=CPU Red=GPU
(If your Having Trouble Understanding Click the Picture)ORTop 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:
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
that is close to the right strength and here
is how it should be used.This post has been edited by Grim187: Sep 23 2011, 01:00 PM
