I wouldn't recommend using the method where you modify a 20-24 pin adapter harness these days. Current CPU's need so much current that even slight resistance in the supply wiring can cause a significant voltage drop. Hence, you don't want any extra non-soldered connections between the PSU and the mobo.

now i know if done right a fire is unlikely. i also have a decent knowledge of electronics. the diagrams are very straight foward.
however, anything that can go wrong will. this could prove dangerous even if done "right".
i did not mean to spoil the party. i am just glad i read the fine print that allowed me to make my decision.
khriez said:Damn... how safe is the guide in the speed3d link? The one where you use a relay ? How would a fire start? I need to know why a fire would start -- so I can find a solution... TRIPLE PSU'S BABY!!!!!!!!!!!
Sure it does.Excelsior said:Erm... Voltage drop does not depend on the current travelling through the conductor with a given resistance.
Yes. In fact, you could just use wire nuts or for that. The green wire doesn't carry much current. What you want to avoid is putting non-soldered connections into the circuit that feeds the CPU.khriez said:You said unsoldered, so does that mean it would still be okay to solder the 2nd power supply green wire to the first by cutting the wire?
Folks from extreme cooling crowd commonly say that phase change is less of a hassle than TEC's. It's also more energy efficient, and if something goes wrong with the system, at least it won't add heat to your CPU.khriez said:Damn a peltier was more trouble than I thought...oh well good thing they are only 30 bucks.
