Corsair 600T watercooled build: "Blue Dragon"

that 5870 actually looks quite nice, I usually don't like chip only gpu blocks but that looks nice :D

I think I may agree with you on the bitspower fittings part, although I used ek compressions, there were a few leaks at first, until I tightened the leaking ones that were on my rad to the point that they were almost wrecking the threads

Thanks mate! But wow, majorly scared of leaks now. If there's even a tiny leak somewhere I'm never going to be able to face running my comp when I'm not in the room, or asleep :p. I want to run the pump at a high setting and I can just imagine one of the tubes just popping out and spraying water all over the insides.....................................................
 
Really wish I'd never noticed this thread. All sorts of expensive ideas floating around in my head now for my 600T!
 
Are you cooling the card like that because you have an Asus rog matrix 5870 2gb, and never thought about water cooling when you bought it. Then once you did you realized no one makes a full block for it like me???
 
Bah.. only bitspower fittings I ever had leaked. Been using generic for yonks and yonks now with never a problem.
 
Big update. Been very busy today, and not very happy with the loop, probably cos I ignored some of the advice in this thread and totally disregarded the impact of flow. I do like how it looks though :). Did the 2nd GPU this morning, only took me an hour this time as I knew exactly what needed to be cut:







Tubing up, and checking every fitting 10 times:



I improvised with bridging the gpus a bit as I wanted it to look a bit unique. The bit below seemed like genius at the time but ahem...you'll see xD.



And leak testing + bleeding:









Need some noms. Temperatures and issues to be addressed later :p.

That's gorgeous! I'll really have to go watercooling on my next build when I go Intel this fall. It looks so cool running as it is.

That really is a monster of a build.

It does look awesome, I'm also going to have a go at watercooling. I'm buying bits and pieces here and there, its already becoming rather pricey! :(
 
Thanks guys! Thought I'd test some temps after the loop was ready, but with only the quad rad running as I hadn't sorted cables for the top rad yet.

CPU
Quad with 4 x GTs running in silent, and Triple on passive...Linx first. 2500k at stock, after 6 passes the hottest core hit 49C tops on load. Not bad...but the gpus weren't been stressed and I'd hoped to get a bit better.

GPUs
Testing GPUs in furmark. What the ****? Bottom GPU is 20deg idle, top GPU is 30deg idle which is ok (top gpu is outputting an image). However, under full load, the bottom GPU goes up to 23deg, and the top GPU hits 65!!!

My first thought here was - dammit, I've ballsed up my crossfire. Ran Heaven benchmark and same result. Then ran a couple of games that I know work with crossfire, still no temp increase on the bottom GPU. Disabled and enabled crossfire, tried new bridge etc. Uninstall, reinstall drivers + latest CAP, same result. Tested bottom gpu and it works properly, outputs image etc.

What the ****??

Like an idiot I only then checked fps with crossfire enabled and disabled, and it turned out I was getting double fps with it enabled. I only then checked the load for each card, and it turned out both were at 100%.

Basically, my loop is cooling the bottom card so that at 100% load, temperatures only go up by 3degs, but because of my 'ghetto crossfire link :p', flow to the top card is being restricted massively, and load temps there are very high indeed. So, sort out that link and hopefully gpu and cpu temperatures will both improve :confused:? Argh need to drain and redo that part of the loop at least :( :(.

Is the flow direction correct for the cpu? I thought the left had fitting should be the inlet on the Supreme? Unless I'm reading the pump wrong it seems to be going in the right hand port on the cpu block.

Not sure if this can be true since at first sight the gpu blocks appear to be in series therefore should have the same flow. I'd be thinking about reseating the block.

Well spotted, you're right! Read the instructions wrong. Looks like it's going to be a total drain job then. Do you know if it's going to damage the block if I continue running like this for a while, or does it just affect temperatures?

Surely flow would drop a lot before the top gpu due to the highly restrictive connectors?

It won't do any physical damage to the block, it just won't perform s well as it should.

The flowrate in a series loop like you have is the same everywhere. The water velocity may change due to changes in cross sectional area, but the actual flow will be a constant, and it is the flow rate which governs the cooling performance. Your top and bottom gpu blocks are getting exactly the same flow regardless of your link. Only if you had a parallel arrangement might you be starving one of them of flow. If the flowrate is the same in two identical blocks when the cooling performance should also be the same, therefore something must be wrong with the mounting.

Well whaddaya know :). I got to dash but will think on this and remount - cheers!!
 
Also I would double check whether your gpu blocks also have a prefered flow direction, as at the moment the inlets/outlets swap round between blocks. This may even be a reason for the temperature difference come to think about it.

edit: infact looking at the 4th photo in post #97, they do, and on the face of it the top card has the inlet in the wrong port, which may explain why your top card is too hot. Mystery solved I think.
