Please spec me a watercooling system

Hi,

Please excuse dust (i'm sure flash makes it look worse) and nasty wiring behind the motherboard side of the case. Is this roughly what you have then cahonis, and is this accurate to what we are thinking is best?

The 120mm rad on the back.

The 360mm rad on the top.

The 240mm rad on the motherboard side.

I have my 240 rad oriented horizontally though.

To get it vertical (as in last pic) you would have to heavily modify the hot swap bays above the drive bay/cage.
 
Yeah, that's where I have my 240 but I didn't mod my case that much.

It's probably not helping my temps as air flow into the bottom rad isn't great but as I'm only running 2x7950's and a 4770k heat isn't too much of a problem for me.

The cards are running stock voltages and the cpu is @4.6. I get cpu load temps of about 55c and gpu load temps 57c. And that's with my PC right near a radiator so ambient temps can be 28c :)
 
After a lot of umming and arring, I have a plan which i'm going to throw out there and see what people think.

The case is the obsidian 800d.

I'm thinking:
The processor is cooled by a h-50 at the moment, I can move that to a top exhaust fan.
The top graphics card of the 3 goes to a 240mm radiator, next to the H50, also exhaust.
The second graphics card goes to a 120mm fan on the back (where the h50 was). I would have it on the top but the tubes aren't very long so I'm not sure they will reach.
That leaves the bottom card and no extra fan spaces on the case, so I leave that as stock.

I then mod the side of my case to add maybe 4 or 5 in take fans in the side window, to pull air in for the radiators to push back out.

That means 3 closed loops (one for CPU, 2 for the top 2 cards), and one on stock... but a huge amount of air flow going round. Hot air will go out of the top and back, and fresh air in from the side.

How does it sound to you? I'll probably do them all in push/pull if possible, and will hook them up with molex connectors rather than a fan control so they will all (including pumps) be running at 100%.

As I have the fans, this means I just need 2 closed loops (one being 240mm and one being 120mm, the 240 for the top card as it runs hottest). I'll need 4 or 5 fan grills for the side window, and I need to spend some time drilling the holes.

It might make a fair bit of noise, but I doubt as much as the fans on the graphics cards.

Hmmm, just throwing this out there as an idea which would cost me about half the price, how about 3 of these in push/pull for the cards? The CPU already has a h50:

YOUR BASKET
3 x Corsair Hydro H60 V2 High Performance Liquid CPU Cooler £59.99 (£179.97)
3 x NZXT KRAKEN G10 GPU Cooling Adapter - Black £29.99 (£89.97)
Total : £279.53 (includes shipping : £8.00).

I need to go looking up some reviews.

Why separate loops? It won't give you any cooling benefit.

Better off putting in a 360 at the top, a 240 at the bottom and a 120 on the back and having a single loop for everything, including the CPU.

If you use thick rads (60mm) it should be enough cooling.
