Help with wc e8400 and 3870x2 (x2) in cf

[Smerlin]

So basically I'm building a rig and have most of the bits I want I just need to decide how many rads I need. I am def sticking with the one loop can't really afford two. Everything I have is listed below.

Cosmos s(with the 300m side fan)
Gigabyte x38ds4
Kingston hyperx ram 4gb t1 with ram cooler
E8600 e0 stepping
2 Ati 3780x2 1gb ati cards in xfire
Xspc x20 CPU block
Xspc 720 dual bay res+pump
2x 3870x2 xspc full blocks
Black ice extreme triple rad.
1/2 I'D hose

Also will be running a push pull on the rad (6fans)

Will the black ice be enuf to wc the gpu's and the CPU(looking to get 4ghz outta the CPU ideally)?

Is it worth getting a signle rad extra and will my pump be powerful enough?

Lastly any particular order I shud plumb it together or does temp just even out across the setup??

Thanks in advance for any help

I would get 2 triples just to be safe or a triple and a double I dont think a 1 rad will be enough tbh. Also the black ice extreme series only have good performance at high rpms meaning loud fan noise.

Have a look at the radiator comparison here. A black ice extreme would be good if you dont mind noise.

Everything else seems fine. Its generally a good idea to have the radiator before the pump/res.

Example loop would be

Pump/res > CPU > Rad > GPU1&2 > Rad

I'd use the Phobya 200mm rad on the side for the GPU's and a 240 rad on the top for the CPU

so Res>Pump>Card 1>Card 2>200mm rad>CPU>240 rad>Res
