Also would i need TIm between the cpu and peltier and waterblock? If i went with your 24v version can I use a standard 750w and convert it to 24v? what would be the easiest / cheapest way to convert it to 24v. I want to stay just below ambient which is around 25c mostly in summer and my cpu idles at 28-32c and 58-61c load.
The 12V 400W uses ~23A so that's a no on the molex, probably a no one a single 6pin PCIe but I'm not 100% sure. You're not going to change the current with a resistor unless you go Parallel, and even then, it's not going to be much.
EDIT: Sorry n00b mistakes, you're not going to change the current unless you change the voltage of the TEC which would be in series. And I don't know of any resistors that can handle 23A.
Yes you would need TIM to ensure that heat is being removed efficiently. On both the hot and the cold side of the TEC.
If you go with the 24V version, you can run it at 12V, which will pull like 12A or so, which will work with a 6pin PCIe, probably not a molex. There is no need power the TEC with 24V, that would make it very inefficient.
