Good day

Due to the recent hot weather the Uk has been experiencing and other factors (Like new pc projects), I`ve decided to upgrade my pc to a fully watercooled system.

Current Specs:-
Case:- CoolerMaster Cosmos II Super Tower Case
Power Supply:- Corsair Professional Series HX1050 1050w
CPU:- Intel Core I7 3970x 3.5GHz @ 4.6GHz overclocked
Motherboard:- Asus P9X79 Deluxe
RAM:- 32GB Kingston "Hyper x" 2133MHz Quad channel
Hard Drives:- Western Digital Velociraptor 1TB HDD x2 "WD1000DHTZ"
Solid State Drive:- Intel 520 Series 240GB
Graphic Cards:- Nvida GTX680 @4GB VRAM each card SLI
Cooling:- Intel Thermal Solution RTS2011LC All-in-one for CPU

Even in this hot weather, my PC is cool but I know it could be a lot cooler.

My current Idea is to go for a three radiator system like the Overclockers Uk "Ultima 460i Scimitar" however my concern is the x1 XSPC EX120 120mm radiator.. I Fear it would be inadequate to cool the fluid from the SLI GTX680`s adequate enough to pass onto the Cpu.
Any Suggestions, Idea`s, Comments would be appreciated because I really would like to make the whole system watercooled....

When you say cool the fluid from the 680's to pass on to the cpu - you need to realise that the fluid in the loop will reach an equilibrium and be within a degree or so all the way round loop. It isn't a case of you requiring cool fluid to come out of 1 component in order to cool the next component in the loop. What is important is your total radiator surface area as it is this that will dissapate the heat from within the fluid.

What that Ultima has is a triple, double and single radiator - in essence the equivalent of having 2 triple radiators, which is going to give very good cooling potential.

As i say the fluid will reach a temperature and that will be the temperature of the fluid in the entire loop until such time as the radiators have time to dissipate the heat or further heat is added.

120x6 radiator will be sufficient to cool what you are looking for.

I just checked out the system you mentioned and you as far as I can see you have the flow idea wrong

The flow is

res - pump -360 rad- cpu- xspc 120 rad - gpu- 240 res- pump/res.

The 120 only takes some of the heat out of the water from the cpu before it hits the hotter gpu. As to how much difference it does make I dont know but I do the same with a 240 xspc rad before it hits my gpu's.

The general rules is 1 cooler space on a rad per item water cooled. so a cpu only could be a 120/140 rad and a sli/xfire system could be a 360/480 rad but most people go for way more in there builds.

Yes, but the order doesn't matter. Due to fluid dynamics, the fluid reaches a temperature equilibrium so the component/ radiator order doesn't matter as such.

What I am saying is that you could have the same system but with no radiators inside the case and a large external 120x6 radiator and it would result in the same cooling potential. You aren't cooling liquid in different sections of the loop prior to the fluid moving on to the next component in the loop to cool. Think of the flow in motion as 1 uniform temperature which will rise and fall depending on the total amount of heat given out by the system and the efficiency of the radiator(s) and fans at removing the heat from the fluid.
