Hmmm - I have alot of worries about this method of watercooling PSUs. I mean - PSUs are engineered very carefully - and that extra impedance could present troubles, methinks. I'm not that much of a electronics guru though - more of a wannabe

Anyways - has anyone ever tried making an actual replacement for the stock heatsinks? I've noticed those are normally grounded - would that be a problem for the waterblock to be grounded? Anyways - touch the wires (lightly - after licking finger) to see if it is warm. If it is - then replace it with a thicker wire. At least that would be my strategy.
