noob question, please help

mmmalas · 03-22-2006, 07:29 AM

hi,

this is my first watercooling system, which I have not built my self!

its an already built koolance system dual pumps, with 1/4" tubing

I bought NV68 for my 6800Ultra, which is 1/2" block

what do I need to convert the block?, sorry I am not familiar with terminology (barbs/thread etc) since english is not my first language

edit: I live in the uk so the shops I could think of are:
http://www.watercoolingshop.com/catalog/
http://www.coolercases.co.uk/
http://www.componentsuk.co.uk/catalog/
thanks in advance for your help

regards

There are a couple of problems you are going to run into.
First, the obvious one - how to connect 1/4" hose to 1/2"barbs. I'd suggest taking the block down to your local hardware store and seeing what sort of threaded barbs they've got and just replacing the ones that are on there. BUT - read on before you do that just yet.
Second, DD trumpets "high flow", which could be good as in "doesn't introduce a lot of restriction to your loop" and could be bad as in "relies on high flow and doesn't cool worth a d*mn at low flow" - and you definitely have a low flow system (I'm hoping it's at least 1/4" ID and not OD tubing).
Third, you may or may not have enough radiator capacity to "shed" the additional heat to the air. I have no experience with Koolance, but their reputation is that they size things to just barely be able to cope with the heat load they're sold to handle. The heat from your 6800 may be more than your radiator can handle.
Fourth, the NV68 is copper. AFAIK (second hand knowledge) Koolance stuff is aluminum. Aluminum by itself in a look will corrode - but it's lots worse if there's copper in there, too. So be sure to use corrosion inhibitor.
There's more, but I don't like being a nay-sayer - and I don't know enough about your Koolance system (and maybe they've improved). How big is the radiator? What kind of pumps? are they in series or parallel?

mmmalas · 03-22-2006, 12:12 PM

thanks for answering, I was wating all day for an answer

the rad is 3x80mm fan.

the dual pumps are submerged with water in the reservoir, and only one tube in and one out, which makes me think that they are in series.

The case model is PC2-601BLW

here is the video review
http://www.3dgameman.com/vr/coolergu...eo_review.html

http://www.3dgameman.com/vr/coolergu...eo_review.html

I already have the blocks and everything is connected, apart from the video card wb.

please if anyone can help, then please do, I have new pc for over a week, and I did not run it yet.

regards

bobkoure · 03-22-2006, 12:52 PM

80x3 sounds like you've got enough cooling capacity.
Might be as simple as getting some 1/4 NPT thread to 1/4" barb adapters and seeing how well things work. Eldon James makes decent ones in nylon, but I've no idea where you'd get 'em where you are.
On the bright side, this GPU cooler is unlikely to present any additional system resistance compared to the 6mm tubing you've got.

Oh - and I'd consider ditching the chipset cooler altogether and converting everything else to 10mm (3/8"). 6mm seems awfully small.
And you might also simply have a mismatch between a "needs high pressure allows low flow" cpu block and a "needs high flow" GPU block.
This is all gear I haven't worked with personally.

mmmalas · 03-22-2006, 01:30 PM

I just want to point out that the block is 1/2",

could you show me pic, of the thing I am looking for

I live in uk, I would thoght some stuff already exist in watercooling shops here.

as for converting everything, I just got everything, so i need to change the pumps, nb/cpu block, so I dont think this is an option really

I am noob to watercooling, so I want somthing that works, not bothered about overclocking at all tbh

You want a pair of gizmos that look like this

It's called a thread to barb (or thread to hose) adapter - you want a 1/4 NPT thread to 1/4" barb adapter.

Your block is not 1/2", it is a block with 1/4 NPT female threaded holes in it - with 1/4 NPT to 1/2" ID tubing adapters.

In the states, the best place to get something like this would be at the local hardware store. I've no idea if your local hardware (stockist?) might have something like this.

mmmalas · 03-24-2006, 04:35 AM

can you look at the links below, and tell me if this is the right one to order

http://www.componentsuk.co.uk/catalo...roducts_id=306

http://www.altecweb.com/home.asp?cat=Subcategory11220

sorry I am not being lazy, but I dont know what to order

bobkoure · 03-24-2006, 09:15 AM

Nope, sorry - BSPP is not the same as NPT.
NPT is tapered, BSPP in straight ("P" for parallel sides).
I think, for 1/4 the thread pitch is the same so you can thread one into the other - at least for a bit. There will only be a few threads that are actually tight enough to be watertight, but that might be fine. At a minimum, use teflon tape or teflon paste.
Personally, I'd hold out for NPT but, hey, that's me...
If you already have the block, take it down to the local hardware store. Tell the folks there you're looking for a 1/4 NPT to 1/4" (or 6 or 8 mm) tubing adapter. They probably have something like that in stock - and if not there than at an import auto place. Get some teflon paste while you're at it..

PS: While I'm at it, 'G' is the name as BSPP - so G1/4 is 1/4 BSPP (same deal as the French not wanting to admit that they set their clocks based on the time in Grenwich)

mmmalas · 03-24-2006, 01:52 PM

ok if I got those fitted into the NV68 block
http://overclock.co.uk/product.php?p...t=445&view=rel

with those tubing
http://www.tekheads.co.uk/s/product?product=601078

would I be able to connect it to my system?

bobkoure · 03-24-2006, 04:29 PM

I did a search for info on threading on that block (haven't seen it, but up to now all DD blocks I have seen have been 1/4 NPT.
From the comments in this thread they might be 3/8 NPT or even 3/8 BSPP.
Here's a picture of two of 'em stacked

Notice the o-ring under the adapter flange? Sort'a looks like a parallel fitting to me - makes sense, given that it's in plastic.

I think I'd better retire as "expert" - clearly I don't know enough about this block...
Anybody else have one in-hand?

Failing that, mmmmalas - can you unfasten a fitting and measure the opening of the hole? that'll at least settle the issue of 1/4 vs 3/8 (and no, 1/4 fittings are not 1/4 across).

mmmalas · 03-24-2006, 04:41 PM

it seems that that whole need 6/19" UNF fitting

ricecrispi · 03-24-2006, 04:55 PM

that was custom added 9/16 hiflow fitting by mod god coolermiester. I think he invented that sli cooling idea and dangerden mod there to be sli like that.

I believe they are g 1/4 Bspp fittings now.

ricecrispi · 03-24-2006, 05:00 PM

Dangerden items (old - pre 2004 iirc) - 1/4" NPT
Dangerden items featuring HiFlow Fittings (2004/05) - 9/16-18 UNF
Dangerden items featuring PerfectSeal Fittings (2006) - G1/4"

I stole this from marci on his thermochill website thread list. Great bookmark to keep.

mmmalas · 03-24-2006, 05:17 PM

thanks bobkoure for you help so far,

ricecrispi, do you have any comment on the above?

I am looking for somthing that work, thats all, not bothered about overclocking now.

bobkoure · 03-24-2006, 09:28 PM

Well, if they've gone to G1/4, then this link (which you posted)
http://www.componentsuk.co.uk/catalo...roducts_id=306
should work fine - at least in the sense of fitting - no idea how dependent that block is on flow, and whether you've going to have enough to make it happy.

The issue isn't how much thermal energy water can carry (it can carry an amazing lot) but sometimes blocks are designed assuming some minimum flow. If you fall below that flow, the heat doesn't get effectively from the flock to the water.

Might as well try it and see...

mmmalas · 03-25-2006, 08:11 AM

I had confirmed that the block is 9/16-18 UNF,
so I think the following solutions should work

or

http://www.frozencpu.com/ex-tub-42.html

I need to get 1/2OD tubing, would this work?
