I have a project coming up to build for a friend. I am going to use a lian li cube case with phenom processor, ballistix memory and two 3870x2's. Will be needing cooling loop for it so am looking for the following:

High flow pump =>700lph*
2 x ek 3870x2 blocks with 3/8" barbs
cpu block with 3/8" barbs*
Radiator to cool all on single loop* & fans
5 mtr 3/8" tube
fill port*
some form of manifold for parallel feed?* (are these even available? would there be any drawbacks?)
resevoir*

would like your recommendations on tagged items and is there anything else I might need.

Cheers

If i was going intel i would agree, but I have 3/8 in my rig on phenom 9600 and even oc'd I have idle at lo 30's and load at high 30's with cpu & vga on the same loop, and that's with the crap pump and rad that gigabyte use.

I think 3/8 should be enough but thanks for the input.

You don't mention your budget, but seeing as it's a high spec PC I'm guessing it'll be reasonably high spec?

Pump: 12V Laing DDC-1T - £40

CPU Block: D-Tek FuZion - £38

I think you'll be pushing it on a single loop - your looking at dropping about 500W of heat into that loop with a heavily overclocked Phenom, so you'll need ~75cfm fans even with a Thermochill radiator (the best ones out there acording to most) which won't be that quiet. You'd be far better off with say 2 x 120.2s, or a 1 x 120.3 and a 1 x 120.2 (Thermochills preferably)

Radiator: Thermochill 120.3 - £56

You don't really need to have to both a fillport and a reservoir if you can access the reservoir for filling, but if you really want to:

Fillport: POM Acetal - £8

I wouldn't bother with parrallel feed, you'll just end up reducing the flow to each one and increasing the temperatures of both of the cards probably, just go with having them in series

Cylinder reservoirs seem to be the most popular, and look pretty good too:

Reservoir: EK Multioption Res 100 - £20

As for the tubing size, you'll probably get a drop of a degree or two if you go 1/2" over 3/8", but if you go for 1/2" you can use 7/16" tubing which is an extremely tight fit - you need a knife to take it off TBH - so there's a lower chance of a leak.

What is the construction on these rads like, is it an open rad like on a car or is the liquid fed through internal pipes between the fins?

Was going to use a backlit bay res and just wanted the fillport so i don't need to keep taking it out to top up.

buggrit, thats what my case came with, thought it worked quite well, looks like i might have to change the layout.

Oh well i was looking at changing the rad and pump anyway

May well do that then, only a slight decrease in temps but it isn't giong to cost much more.

It's fed through internal pipes. Thermochill radiators are very thick, so it can be hard to find somewhere to put them, but this means they offer a much bigger surface area than other radiators

Fair enough, sounds like a fillport is a good idea. Danger Den also make fillports which are pretty nice quality (I've got a black one lying around at home somewhere which I keep meaning to use but it's slightly chipped) - they are £10 each

If you want to do a single loop, your best method is probably:

Pump -> Radiator -> CPU -> GPU -> GPU -> Reservoir -> Pump

Like I said, you'd be better off with dual loops though

I would personally say the extra safety is worth it.

A note - if your using 1/2" on the D-Tek FuZion normal clips won't fit, your best bet is to use som wide cable ties
