well, i have an enermax 431w ps, and i was getting a horrible +12v line drop because of the compressor in my vapochill. so i am reading on the VC forums, and with the help of bulldog and ranger.gav, i did the mod to this powersupply to up the voltage. i added a 1 K ohm pot the a resistor on the ps, and now i can adjust the voltage, i have immediatly went from 11.61 to 11.91 on my +12v line. i have to still tweak it. the best part about it is i can adjust the pot through the fan when it is not spinning.
