Cheers gmat, I was'nt to sure about the 5vmobo mod, it seemed alot was'nt explained properly. a new PSU is in order I think (Antec 550 T/P@?99). how come the 5vSBV 3.5, 1.5AGP and 2.55DDR V's are all fine, it's only the +5&12 that are diminishing?...

Because those are the lines where current is drawn. 5V powers electronics components, and 12V powers motors and high-current-draw components through mobo regulators. You can easily get a 10A draw on the 12V and a 5A draw on the 5V, or more. The -12,-5 and others are there only for reference points, a few Op Amps, and basic mobo functions (BIOS with CMOS save, power save, etc) so they get almost no current.

flux is the key I think, and tinning the wire properly...

You know what you're talking about. Good luck then

O/T, did we ever pick your brains about a way to make a Eheim1250 start in the same direction every time?, the sine wave of the AC means it'll start either clockwise or anti~clockwise. if it could be controlled it'd be easy to mod the pump for more flow+head ...

If we could get to the motor coils, yes. A variable impedance controlled by a JFET at startup would 'dephase' slightly the sine going to one coil, making sure the first sequence followed by the rotor is 1->2 and not 2->1. But with no internal access to the pump electrical guts i dont see any easy solution...
