The problem is that the fan header in the PSU is delivering 12v, and this is interpret as "max" to the fan. Try cut the 12v trace and find a 5v and jumper it to the pin, or get a resistor to limit the current a bit. I did this mod to my Amiga 2000 PSU, and the only solution was the resistor (12v = super noisy, 5v = almost no spin at all, resistor = perfect).
Even cooler would be to find a trimmer resistor (pot) and drill a hole for it in the PSU case -- which results in super cool user-adjustable fan speed!
