    I have two build creeping along at the moment. This is for the slightly slow one (It started in 2006). The config is

    • PC-6 Case with Top 240 thick Rad , Bottom 360 medium rad. Can't recall what fans at the moment.
    • 2 Pumps, Laing DDC 12W and 18W.
    • QX6950 (I think) on a X48 Rampage Motherboard and EK waterblock on the heatpipe.
    • Dual 5770s in crossfire
    • Dual
    • T-balance Big-NG , flowmeters, Zalman power monitors, any other junk I could plug in.

    I was going to have the CPU & NB on a loop with the 18W pump and the 360 rad and the graphics with the dual rad and the 18W. Part of the logic is that with the pumps and fans controlled off the T-ban, the graphics loop would only really get pumps when I was gaming and the top rad was goign to be nosier than the bottom one.

    Does this make sense or shouId I pump the fatter pump on the cpu....


    Any thoughts?

    (I'll try and post a pic of the rig, wip at the weekend when I get home.

    Don't mean to be rude, but what is the point of this build? Pairing and aging CPU with two very very old GPUs (the 5770s are basically 4870s) for a new watercooling build is counter productive.

    I'm pretty sure that was slightly rude haha. It's still going to game pretty darn well when it's built.

    I'd probs put the 360 rad with the GPUs and the 240 with the CPU+nb. Which pump you use all depends on how restrictive the blocks are. Are they full cover GPU blocks?

    Have you considered solder-modding the lower wattage DDC to 18W? ;)

    Yes it's a bit daft. It's been overtaken my a new mATX IVB build but I've been tinkering with this beast for so long I can't quite face giving up. Crossfire is silly, but somehow in keeping with the project.

    CPU block is somethink like a EK Supreme and the NB is their EK-NB ASUS HP

    Graphics blocks are full cover.

    I'd just do a single loop with the triple rad. The dual rad would be enough but the triple would mean you could run the fans a bit slower.

    In all truth it came about because I bought a case cut for two rads and with the T-ban the idea of having them spin op separately was just too tempting. I have the rads and pumps installed and even got the rather fun TecnoFront Challenge X2 Reservoir so I have to go with it.

    My problem if they I get rather hooked on making everything as complicated as possible and thus just buy more and more parts and don't get anything built. So I'm trying to work it out of my system with this rig. Hence the huge case and moutain of parts. A couple of photos migth explain some of the madness.

    I'd still do a single loop using both rads. The HD5770s only put out 110W each when fully loaded so water temps will probably only increase by 1ºC with them in the loop. The QX9650 if overclocked heavily will probably use around 200W. You'd only need slow speed fans (depending on the rads) for very good temps

    If you can mod the 350 pump to 18W or undervolt the 355 pump then with dual pumps you'd have redundancy. You wouldn't need both pumps though.

    I didn't have a chance to make any progress this weekend but here is the rig as it sits.
