Problem designing water cooling system

Hi

Im looking to overclock my PC, using water cooling.
The company "www.digitalstormonline.com" say that you can use just two 120 rads to cool a cpu and up to two graphics cards.
Is this really right?
Ill be using a CM Scout, i5 and two 4870s

Thanks

Two 4870's need a 120x2 rad at minimum and higher speed (louder) fans to cope. An i5 needs a 120x2 to function.

So no way, unless they let the CPU and GPU temps get stoopid and use higher speed fans.

Watercooling is a hobby, and isn't something you should ever prebuy in a prepurchased system.

No way

air cooled hd4870's get very hot i know i have 2 and they require my fans speeds set to 50% or they crash in game :p, although i have more heat generated in my case than the average user.

i got 1 with a ref cooler which is the worst :p and the other is similar to the vapourx design and they both overheat tbh but the stock one is louder to achieve the same temps
 



i don't even have the vaporx design, just the sapphire heat pipe design and it never even comes close to over heating, then again i have a 120mm fan blowing right on it

Ok I just found another strange product:

The sapphire 4870x2 atomic manages to squeeze two RV770s and a CPU block into one 120mm Rad!
GPUs get to 54 degrees under load, CPU at 48 degrees idle.
Thats pretty impressive for a single 120 I think!

Impressive for a 120 rad to cool both. Good temps? Nope.

You mean a 4870x2. Not some arcane chip name. It's a 4870x2.

Hmm no metion of ambient temps or what it was installed in/on. I can pretty much bet it wasn't inside of a case.

So the test has very little validation, usually expected and written into a review. Actually, reviews isn't where we find out best data, it's tests done with consistent scientific methods, like here.
