Hi Everyone

I have just built my first Gaming PC and am interested in water cooling my components. I have spent quite a bit on this rig and would like to install the best possible cooling system i can regardless of cost. I have read through a fair few guides but am still undecided.

My system consists of the following components:
-Cooler Master Cosmos II Ultra Tower
-Intel i7 4770k
-Asus Maximus VI Extreme Motherboard
-Asus GeForce GTX 780 x3
-Corsair Dominator Platinum 2x8GB 2400Mhz
-Thermaltake Toughpower 1500W
-Creative Sound Blaster ZxR
-WD VelociRaptor 1TB x2
-Samsung 840 Series 120GB SSD

From what i have read i have semi-decided on the following for the water cooling:
-MCP655-PWM Pump
-EK-FC Titan GPU Water Block (Very unsure of which model to get, read a lot about nickel corrosion)
-EK Supremacy CPU Water Block (Again unsure of which variation to get)
-EK-RESx3 Reservoir
-Primochill LRT 1/2" ID tubing
-Bitspower Compression Fittings
-Still unsure of a good radiator that will fit in the rad bay of the Cosmos II

So i suppose my questions are:
1) Are these cooling components sufficient for overclocking my system/are there better alternatives?
2)Is it worth water cooling RAM at all?
3)Should i make two seperate loops? One for CPU (and maybe RAM) and one for the three graphics cards?
4) If i should have two seperate loops, should i have two radiators or a split one, and will my pump handle it or should i get two?
5) Recomendations on cooling fluid? Have read alternating views on corrosion inhibitors and kill coils.

Any help would be greatly appreciated.

Thanks in advance,
Andrew

I use an EX360 rad in my loop, it's a good option if you want a cheap but good performing rad. It also doesn't need amazing fans to get close it its best performance.
However in this case, especially since you want too keep everything internal, you will want as thick a rad as you can get. The EX series is a slim rad option, something like a thicker RX rad might be more suitable considering that you have a lot to cool here. You will also need fairly good fans to get optimum performance from thicker rads, though that performance will be above what you can get from an equivalent size slim one.

Fans, good water-cooling fans are Scythe Gentle Typhoons, Noctua NF-F12's, Silverstone Air Penetrators and Corsair SP120's. Those are your top-end...
Its fairly late where I am, so feedback will be brief.

1. You will need far more rad space than whatever can fit inside a Cosmos II to cool all that adequately, look into external mounting or a rad-box solution.
2. Nope.
3. Depends on what your goals are. Simplicity, go for one loop. Performance, go for dual.
4. Again, you will need a ton of rad space for this. Two seperate loops, you need two pumps, two res' and enough rad on each loop to deal with whatever is being cooled. You cant share components between them otherwise your back to a single loop and depending on how its done it could kill your performance.
5. Distilled water + Killcoil/Biocide is my recommendation. No need for bottled stuff.

Thanks for the quick response.
My goal is definately performance. I haven't measured it out yet but im pretty sure i can fit two pumps and two reservoirs into the empty space of the main area of the case.

I have read that the XSPC EX360 radiator will fit into the top section of my case. Was thinking of installing another in my empty HDD bays at the bottom of the case.

Do you think this radiator and the other cooling components i listed are the best options for performance?

Feel free to go to bed before responding:)
Thanks again
