Help with radiator

[HawkJ]

Hello. I am building a custom water loop. Planning to cool the CPU, two GPU's and the motherboard itself. So how many minimum rads do i need to have to achieve good temp? 

 

And what is the best rad to go for?

usually start with 240 then add 120 per component, some components need less than others like your motherboard doesn't need as much as your gpu.

Thicker the rad the better, copper>aluminum.

For that setup, I would recommend 4x 120mm of radiator space. Also, there isn't much benefit to watercooling to motherboard if you're not going to be using ln2 or pushing a butt ton of voltage through it.

Actually i am planning one right now. Ill either be going for

 

GPU - dual 780.

CPU - i7 4820k

Motherboard - Asus Rampage 4 Black Edition

 

OR

 

GPU - dual 780.

CPU - i7 4770k

Motherboard - Asus Maximus 6 Formula

Since you're going for a quad core Ivy Bridge E, you should get a regular i7 instead. I think the 4770k and the formula is a better solution.

Yeah. True. And should i use the built in water cooling loop on the formula or should i get a new full motherboard instead?

You don't need to cool the motherboard, but if you seriously want to for the better aesthetics, you can use the integrated block; just make sure that your coolant has an anti corrosive since the block if made out of aluminum.

True. Thank you so much for the opinion.

So a question for that. If you can sufficiently cool the cpu and power delivery on the motherboard can you get away with running higher voltages and still have it be stable?

Yes, most likely. But what I meant by ton of voltage is like 1.4V+
