Single loop or dual loop? - Page 3

post #21 of 25
General rule of thumb is 120 to start with and 120 for each component you want to cool, and then 120 per overclock (and 120 per component you want to cool silently)

So since you want to cool two components, both overclocked, ideally you'd be looking at a 360 + 240. 120 definitely is nowhere near that, the least you want is 240.

Alright yeah, but I can't and won't go with all of that, because even if I had the disposable income to do it, all of that would never fit in to the prodigy... comfortably anyways.

I was thinking of going with a Swiftech MCRx20-XP dual 120mm rad and just be done with it. Pretty much the best option I can come up with, short of taking the gpu out of the equation, which I don't want to do.


Besides, I won't be doing any heavy overclocking, and there will already be 2 more fans within the case pulling air out.

How big of a deal is noise to you? If you're willing to use some powerful fan you could get by with a 2.120mm rad with two devices and decent overclocks. Being that most people don't want noise, you probably aren't going to do that. The best option would be to keep the GPU out of the equation on the liquid cooling loop, and spend the $80 something you'd spend on a full coverage GPU waterblock on an aftermarket air cooler for the 670. I'm pretty sure the 670 would do fine with a high end air cooler.

However when you add 2 or 3 gpu's you're talking about 5 times more heat due to the gpu's compared to the CPU.
If you put those gpu's together with the CPU you do get lower temps on the gpu, but definitely higher water temps over the CPU.
Since gpu's mostly tag along at ridiculous low temperatures anyways while the CPU is pushing its thermal limits at high overclocks you can definitely benefit from colder water over the CPU.

All of this.

Multiple blocks will always do better in a dual loop,having multiple heatsources in the same loop has a knock on effect to others down the line.
Its really up to the individual user.
I run my rig completely series with no problems tho and I have more heat going in to it than most.

I see a lot of misinformation in this thread....
