Ok,
what about these?
$3.99 for 20 diodes w/ free shipping...
5 diodes needed for full PS output per pad. 0.5V drop at full load = 1.5W
per diode max. Use 10 diodes per pad, so 0.75W dissipated per diode
max (probably less since each diode would see 1.5A max load). A diode that size should be able to dissipate that amount of power by itself, or just mount them all under the PS fan.
It may be a bit clunky looking, but it would fit into the PS case no problem.
