Nuno, about that power supply

[Scout255]

Wombat: If it is too load, hoot up the ground wire to the red wire from your P.S and the positive to the yellow wire.
This will lower fan voltage to 7 Volts, which will lower the fan's RPM considerably and hence a quiter fan.
This will affect the alpha's performance (by about 5-7%)

I know that trick, but I appreciate the help. Thanks. Are you sure the performance difference is so small? This Athlon runs hot @ 1.95V, but that's what it took to keep stable.
