OK... So I know all the basic principles of constructing a water cooling loop however I am a little uneducated on heat dump and how much rad is needed.

Everytime I think about building my new PC I'm leaning more and more towards adding my GPU into my loop.

What I would like to know is how much rad would I need for the following loop ::

i7 920 OC'd @ 4.0GHz (needs 3x120mm to istself AFAIK)
Full motherboard colling on EVGA X58 SLI LE (NB, SB, Mosfets)
ATI Radeon HD5850 (stock)

So How many x 120mm will I need...

The plan at the moment is to mount a Feser Xchanger 480 on the top of my HAF 932. I made those Radiator spacers... they have 55mm clearance above the top of the case.

Will I need another 1x120... or 2x120? The Single is easy to mount inside the top of the case using the 4 reamaining screw holes.

I will need to keep the PSU at the bottom of the case in order to route my tubing properly... therefore putting a rad at the bottom is out of the question... and therefore may prove difficult to find a convenient location for a double... but if it's needed it WILL be done.

ANY input is appreciated...

Thanks in Advance...

I say put as much rad as you can in. Future proof ;)

You'll more than likely want to have the GPU in the loop though... probably more so than the CPU. The fans on ATI cards can be really loud, but at the same time, if the 5850 is near the 4850, i can't see it needing more than 1x120

PS. I have no experience with WCing, i'm just putting my logic in lol
 
for that much i would want 2 triple (6x120mm) or more.

triple for the i7 with high overclocks

double for the gpu

single for the board, but if you can swing it a double.

i didn't calculate the heat dump from each part, just going by what i read about from several forums and my personal experience.

Thank You

So if I do 6x120mm... A 480mm and a 240mm... It's easier for me than 2x360mm.

My other option would be for me to squeeze a TFC Monsta in the bottom... abandon the top 480... It is doable... just a little more expensive.

But then again it will cost me £150 ($250) to add the GPU to the loop... I'm thinking it's not worth it to be honest.

The Quad (480mm) should be enough for the CPU and Motherboard.

You really dont need to cool the GPU. Itll run fairly cool w/ a low-medium fanspeed stock. Unless you plan to overclock it and you dont want fan noise, you can get away without it.
