CPU + Duel GPU loop first time watercooler help please.

post #1 of 13
Thread Starter 
Right so I've hit a point where I want to start WCing I am bored I have money burning a hole in my pocket and I am getting the itch to do some upgrading on my rig tongue.gif So given that I really don't do anything that really taxes it as it is I figure hey its time to upgrade in a different direction at least until i see what bulldozer can do vs SB tongue.gif

So basics, I want a WC loop that can cool my cpu, and my duel 5870's

Having read around it a fair bit I have come up with a shopping list, but I would like for some old hands to take a peak and let me know what I am missing as lets face it as a nooby I am bound to have made some mistakes tongue.gif

Case: my 922 is plenty big enough for air but A its industrial looking to the point of ugly and B kind of restrictive for water. So I'm looking at a corsair 800D seems to be plenty big enough and i really like its sleek lines.

Blocks:
Cpu = EK supreme HF full copper or Heatkiller V3
GPU = EK full cover for 5870 or XSpc Razor fullcver 5870- seem to be the only one readily available for my card in the UK

Pump & Res:
Now this is where I start getting really confused tongue.gif Ideally I would like I think... a Duel bay res with an integrated pump something like this Would that be suitable or would it make a significant difference to bump this up and Buy the same Res made to take a Laing D5?

Radiators:
I know the general formula of 120mm of rad per component but this very imprecise. Is there any solid resource with most common Rads and the total Wattage they are able to dissipate available?
I am thinking Black ice 360 in the top of the case and 2 140's one on the back and on on the bottom. Is this going to be too much too little?

Fans:
Thinking Push pull if I have space shrouded Gentle typhoon seem to be popular but this is certainly an area I know virtually nothing about tongue.gif

Tubes will be 1/2" connectors will be compression Coolant will be pure distilled.

Any advice you can offer would be very much appreciated, my budget is negotiable and reasonably high but I would rather not go completely over the top if it isn't going to net me any significant advantage tongue.gif

Wow for a first time wcer you have done a pretty good job picking components. Your link to the pump/res is broken for me but generally you dont want to do that combo. You would be much better of getting a good pump and a small res to either be mounted in the case or to go in one of the drive bays. For res, the type doesn't really matter. For pump, i would recommend the swiftech mcp-655. They are the best. The corsair 800d case is amazing for watercooling. You won't be disappointed. And that radiator setup sounds perfect. A 360 rad would be a little small for a cpu and 2 5870s but add the 2 140s and you should be in great shape.
In terms of tubing, get 7/16" tubing and put it over 1/2" barbs. The tubing will be roughly the same size for waterflow but it will be a tighter fit and will prevent leaks. And those fans you picked are awesome!

edit: with 2 gpus, 1 cpu, and 3 rads, your loop will be somewhat restrictive. Make sure you don't cheap out when buying a pump because that will most likely make your break your loop. You need a pump strong enough to keep the water flowing in such a restrictive loop. That is why i recommended the mcp-655.

I would go EK on CPU n GPU blocks EK makes great water blocks.

The 655 is perfect for your loop.

The res is purely aesthetics.

Rads at least a 360 an additional 120 I would recommend. DADS makes a great rad imo but I have herd Good things about the black ice ones as well.

The GT AP-15 are good fas with a nice static pressure so you don'need the shrouds

Over all it looks like a soild setup. For the.tubing 7/8 is works well with 1/2 barbs but you need to heat up the ends in boiling water for an easier fit.

thanks like I said I have done a bit of homework ^^

yeah links done something weird will fix that tongue.gif how much of an advantage is it going for a separated pump and res combo? I only ask as I like the idea of how tidy it all is in the 1 box which is designed to fit somewhere already built into any case tongue.gif

Will Barbs be better than compression fittings? Not having used either I like the idea of compressions as they seem more secure and also will allow for easier cleaning etc

Compression look cleaner than barbs. Barbs are cheaper. Those are the main differences. I use barbs but am switching to compression when I clean my loop next time cause I like the looks. I went with an all in one res with my 655 I got the XSPC res that fits the 655 and I love it.

Compression looks much better and is less to worry about. Just be careful not to cross-thread but overall if you have the $$ they're better.

Since you supposedly have money burning a whole in your pocket...
With 1 CPU, 2 GPUs, and 3 rads, considering 2 pumps would greatly benefit your loop.

Can you explain why the extra pump would be a benefit? I'm planning a similar setup to the OP. I've been reading a lot of conflicting opinions on if you really need dual pumps or not as the only benefit seems to be redundancy. Even with the OP's build, the restriction doesn't seem to be enough to warrant the extra cost for a couple of degrees.

With the cost of another pump + dual pump top, I'm struggling making a choice on 1 pump or two. If I'm incorrect, please correct me!

In other thoughts, would i possibly be better off just doing a CPU loop and using Accelero Xtreme 5870 air coolers? from what im reading the deltas on those are realy awesome,

Rather than 2 pumps on 1 loop would spliting to 2 loops one for the gpu and one for the cpu work? is that realy neccessar.

Bear in mind Im really not looking to hit any insane OC's mostly just want to bring temps down without my pc sounding like a jet taking off tongue.gif

You can get through the 2 GPU 1 CPU 2 Rad set up with a 655 or 335. That set up isn't terribly restrictive however if you add mobo sinks and ram sinks you may encounter flow issues but other than that stick to one loop.
