Hey everyone, I'm trying to get together a custom loop to cool the system in my sig. I'm heavily overclocked.

What I have so far is:

Pump:

Swiftech MCP350
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

GPU Blocks:

Swiftech MCW60 VGA Cooling Water-block with Ramsinks
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CPU Block:

Swiftech Apogee GT
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Radiator:

ThermoChill PA120.3 w/shroud
http://www.dangerden.com/store/product.php?productid=20...

And will use the Maximus' stock waterblock for the NB.


What reservoir is recommended? Am I forgetting anything? Any help is greatly appreciated.

From where Ive been looking...the D-Tek Fusion is the best CPU block

The Swiftech micro res. seems to be popular
February 2, 2008 1:58:35 AM

+ on the Swiftech micro res

-Need three 120mm fans for the radiator. For this rad, CFM anywhere from 50 - 100.
-Need about 10 hose clamps
-Need about 10 feet of tubing. I'd go with 7/16" ID Tygon or MasterKleer.
-Need Additive - recommend either swiftech HydrX or pentoison plus PT Nuke from Petra's. Could go with an all-in-one like PC Ice.
- Need a couple of gallons of Distilled water.

There are a few things that should be considered here if you do intend on heavily o'clocking. First, do you just intend on o'clocking the CPU or the GPU as well - this could really influence what you might choose as far as cooling solution compoennts because if you intend on o'clocking all the major components then some of them may end up sufferring from the heat of the other components before the coolant hits the rad.

In a single rad solution, it really doesn't matter how good the rad is if you heavily o'clock thigns like both the CPU and GPU (and the effects will worsen if you are in SLI or Crossfire). One component (presumably the CPU - assuming it is first in line AFTER the pump) will benefit fromt he heat exchange of the rad but the components that follow the CPU will have to deal, not with just their own heat but the heat from the CPU as well. I only mention this because you said that you heavily o'clock but you didn't mention - specifically - which components.

Thanks for all the replies!


@phreejak
I only really delve into the CPU OCing, the cards are *slightly* overclocked but it's only a 3-4c difference under full load on air.

The EK Supreme is actually 1 or 2 degrees better than the Dtek and cheaper too.

For fans Id get as powerful ones as possible but dont go over 30dba as you probably will not like the sound!

For me the favored tubing is 1/2inch. So thick and strong and tons of water transfer.

Reccomended res.. well a small one is better IMO it makes no difference really, I use one of the 150mm XPSC passive res and I dont like it much lol, too big.

1/2 ID tubing will be a little easier to fit on to barbs. 7/16 ID tubing is only slightly smaller and will give you a tighter and more secure fit. EITHER will work nicely. Your choice.

BTW hawkspur, how do you like that case? I have the original Armor. I love it, but cable management is a challenge. Looks like TT may have fixed that with the ArmorPlus.

go with tygon thick walled 1/2id tubeing i got it and it doesnt kink, it looks like you have money to burn so id sujest a much more powerful pump im useing a alphacool ap1510, and a ek supreme which is the best waterblock out there but you need good pressure because it had a big pressure drop. rad is fine you cant get any better, gpu block just go for cheapest they all do the same job equally aswell. as long as its full cover(mem aswell as gpu)
February 2, 2008 11:24:40 AM

As far as a CPU block is concerned, you couldn't go wrong with the Apogee GTX, the D-Tek Fuzion (with nozzle kit) or the EK Supreme - those are pretty much the top three and they all function within a few degrees of each other.

With the size of your cooling loop and the number of waterblocks you might be involving you might consider a slightly more powerful pump to power it.

If you will be going to a 1/2 ID setup then I'd recommend the MCP655 (DD5 Laing) which is naturally setup for 1/2 connections. It is very powerful 1400LPH and is dead quiet. The AP1510 from alphacool is slightly more powerful (1500LPH) but has the DC voltage converter that comes with it that you have to place and it has a 21 - 35dBa sound level which is noticeable.

The GPU block you've listed is nice - and it will produce far better results than the fullbody gpu waterblocks. I don't think there are very many GPU waterblocks out for your vid card right now so your choice is an excellent one. If you use a fullbody waterblock then you'll have to deal with the pressure drop due to all the tight bends and turns of the water channel.
February 2, 2008 11:43:59 AM

I don't really recommend the Apogee GTX.

I've been reading around lately on watercooling and the GTX has a problem with the aluminum top and Galvanic corrosion. You could get the copper top but its $30 on top of the $70 for the block and $100 seems like a rip to me.

@OP: You seem to have a good amount of cash to spend (based on that computer in your sig) so I would not wimp out on any parts. Full blocks seem silly to me because as soon as you get a new card you have to change the blocks. But that Swiftech is very universal and probably still be used. Also if you want the best performance you might want to run 2 separate loops. 1 for the CPU and 1 for the 2 GPUs.

No doubt you'd get better performance with separate loops for 2 GPUs and a cpu. But it means two pumps and two rads. That's not a problem - just a consideration.

@Tony

The case is great, suberb airflow, and cable management was a breeze. It came with 3 different kinds of zip ties and clips and has plenty of extra room. It is a little heavy and big, but that isn't too much of an issue.

@Everyone else

Thanks a bunch for all the info, very very helpful :) . I think I'm going to go with half inch tubing and the MCP655 as the pump. I'm not to do two loops as the GPUs are going to be on the end of the loop and can take the extra heat anyways, course I might change my mind depending on what the temps are once I get everything set up.

On tubing...I suggest 7/16" tubing.

It is just as good but will make a better leak-proof seal on the 1/2" barbs. Just dip the end in hot water to make it expand and then get it over the barb
February 2, 2008 10:20:12 PM

7/16th tubing it is then :) 
February 2, 2008 10:44:34 PM

good call :D 
February 2, 2008 11:26:00 PM

Make sure to use hose clips too though, I made that very silly mistake when I was first starting out...
February 3, 2008 12:43:35 AM

I already have a ton of clips, Asus was nice enough to include a crapload with the motherboard.

Well thats it! Any final comments or suggestions before I take the plunge in the water cooling pool? All you guys' help has been greatly appreciated.
February 3, 2008 9:32:20 PM

Yes...the CPU Block

Go with the D-Tek Fusion. Its better and Ive heard problems with the GTX having galvanic corrosion because of the aluminum top. That will cause bad problems if it happens

Also for GOOD cpu and 2 gpus you might need a second radiator (2 fan)
February 3, 2008 9:42:35 PM

The Fuzion is sold out everywhere I've looked though :*(

I might just end up doing two loops with a 120.2.
February 3, 2008 9:52:47 PM

I think Petras tech shop has it in stock...

good call on the 2 loops. It will suit you better.
February 3, 2008 10:01:46 PM

*cries into my wallet*
February 3, 2008 10:04:13 PM

now your crying???

for another $80 pump and a $100 rad...
I would've cried when I got that $1100 QX9650. I would've cried again for those 2 3870s, and again for that PC&C 850 PSU and that monitor and that motherboard and that ram... :cry: 

I'm getting a better cooler though!! :D  but know your getting WCing :cry: 
February 4, 2008 12:56:11 AM

Oh shush :p 

The components were a graduation present, now I have to pay for the watercooling stuff lol.

And the PSU is two years old from my last build!
February 4, 2008 1:05:13 AM

O sorry..

damn graduation

GIANTS WIN!!!!!!!
February 4, 2008 10:08:42 PM

Well I just got all my stuff ordered. Petras ran out of the Fuzion so I had to go through about 10 different websites to find it in stock.

Once I get all of the components by the end of the week I'll be sure to post some pics and benchmarks for the people who helped me out :) 
February 4, 2008 11:52:08 PM

sweet...thanks

Hope it works out well :) 
February 5, 2008 12:48:14 AM

If you are going to use the Fuzion on a quad processor make sure that you get the nozzle kit to maximize the waterblocks potential for that particular type of proc.



February 5, 2008 2:13:33 AM

I did, I had to order it from a different site though :p 
February 5, 2008 2:15:33 AM

better post pics :D 
February 5, 2008 2:58:14 AM

I will, I will! It'll probably be by the end of the week it all comes in, can't wait!
February 16, 2008 10:49:15 PM

Hey everyone, I have all the stuff in and managed to get the CPU/NB loop up and running but I ran out of tubing. So until Monday I wont be done!

After everything is finalized, pics and temps and such will be posted.
February 28, 2008 3:04:14 AM

Pics were promised and so they will be delivered. It took longer than expected, but I'm more or less at where I want to be. Temps are only about 3c above ambient at idle and about 10 at load. Good stuff.







February 28, 2008 10:36:24 AM

Have you considered using Coolsleeves in your loop? As tubing gets heated, it gets more flexible and in areas like between your NB waterblock and the CPU waterblock it could kink up if the bend is tight enough. Also, the tubing leading from the reservoir to the pump could flatten out. Coolsleeves would help guard against all that by helping the tubing maintain its wall integrity.
February 28, 2008 4:34:25 PM

That's a nice looking setup. I see you went with the Fuzion. What kind of temps are you getting?
February 28, 2008 9:51:19 PM

35c idle 44c load at 4.2 and 1.475 vcore :)
