C.E.L.C. (Custom External Liquid Cooler) - 'I have a dream"

[rappet]

This is the formation update I am thinking of now.

CELC-formation1b.jpg

The length of the tubes are not defined yet.. it is a scheme to find out what to encounter.
For now my biggest headache is how to get the tubing inside the Corsair 780T case... from the backside where the tubes entry to the in and out of the parallel multi linked 3 sli cards.
In the schedule it is drawn as flexible tubes, but probably that is not possible because of the angles and short distance they have to make.
Using fitings might give too many short pieces.... anyway I am trying to find out possiblities here.
If you have any idea or tip... very welcome

The photo is someone elses config I have found on the internet, and it shows where the tubes make the entry in a 780T case and I have sketched my scheme in red.

I can still decide later to go for the combo (pumps/top/reservoir) inside the case.. if it fits.
I also have another issue.. the PSU; I have to upgrade it to a 2kW PSu, or add one I have 850W as second PSU, but then that on e as to go external too.. I will get back to this issue later.

greetz,

PS
It is a fun and learnful journey wandering around ojn the internet try learn about the 'watercooling world'

Just a thought, but you are planning to build a room/chamber for putting your PCs in, right?

Have you considered getting rid of the cases all together? It seems that a lot of what PCs do is use fans to move air (often poorly) in a tight space to improve circulation. In the open fans, and pumps would be louder, but you could work on making the chamber silent. However working on and playing with your water systems would be much much easier.

I have another question about all this. What will you gain in terms of performance? Could you make that up by not going with the water cooling, and upgrading your older machines with, say, Titan X's?

What I want to try, when CoolBox will be ready, is to remove the panels of the cases and see if the airflow will improve or worsen. I thought in general the airflow gets worse when open the case, because of disturbing the airflow and cause turbulences unwanted.
I tried removing the side panel with the 780T (another thread) case and it unexpectedly improved performance.
Ofcourse it says nothing about other cases and also depends on the ambient airflow.
So... I am looking forward to experiment when Coolbox is ready and have a airflow with airco

I have another question about all this. What will you gain in terms of performance? Could you make that up by not going with the water cooling, and upgrading your older machines with, say, Titan X's?

I am not only doing this for performance gain on short term but I want to get ready for performance gain in future.

I got some numbers (i.e. Smicha) that watercookling would give 30-35% performance improvement.
So with watercooling triple Titan Z they will perform like 4 Titan Z on air.
For me that is a good investment reason to stick these cards on a 6-slot mobo in a beauty open case, and I can not do that better with other cards. This way this build transforms from 2x Titan Z on air to 3 Titan Z wtercooled, and that is a hack of improvement! And triple Titan Z is still unbeatable by quad X, right?
This way this build imo gives maximum performance possible for 3card setup in this 780T build.

Doing it this way it gives my other builds (in bigger cases with more slots) room for adding another card (that is on the shelf now ) to match up the 12 GPU limit in networkrendering.
For future performance upgrade I have in mind to wait a while and when new generation card (Pascal?) comes out I might swap triple 780Ti (3gb) card with triple new ones on air... or even quad on water if my experience with wc is more experienced then, and budget allows it ofcouse

So, this is more for long term, and also gets me into watercooling, which is fun...
and which is scary road for me too, to walk on as newbee... but let fun prevale

greetz,

Rappet,

Your plans sound great. I see your enthusiasm about WC - good, because it's addictive

I bet (I can feel it in my bones) that Z can be OC to score something around 240 so with tripple Zs you should exceed 700 score. Just use 'proper' amount of cooling radiator units - 9-10 at least.

Good luck!

Yeah... fun and games.. it is you and that 'other' guy to blame... lol

I will mostlikeley go for the external rad watercool-mo-ra3-9x140 pro black...
I start with 9 fans... if not enough I can add another 9 fans on the backside for push-pull. Should be enough, right?

[smicha]

Push-pull is rather for quiet operation so if you want to reduce noise go for it. But real temp reduction comes from radiators surface area - the more the better.

On the other thread you wrote about calculating 1.5 for each gpu... that way I calculate 6GPU for triple Titan Z and 9 will do.. So the mo-ra3 with the 9fans will be OK.

Does the good airflow in the case still have influence on the GPU temps?

That's right.

Of course. Despite WC cards and mobo are still warm (if not hot) so there shall be some 'support' for them. I keep top fans on 480 as exhaust and it's all cool inside a case.

PS. Yesterday I had a disaster - old phobya died and water started to leak. 2xd5 simply destroyed this shitty radiator. Tomorrow I am receiving a new 560 Hardwarelabs Black Ice rad. On one airplex 480 I still am able to render with temps around 50C on 4 gpus.

Nice to see this thread growing =) I just assume that "other guy" to blame was the one now writing =p sorry, it is addictive..but we said that earlier =DDD

Hehe, back to the theme, You still need to have good airflow to keep motherboard happy as it might get hot enough if You on x58 chip still (as I remember You planed to convert that one =) less or more airflow will not make a difference in GPU temps - they will be more tight to flow, fans on rad & such =)

As mentioned - don't think of extra 9 fans, better take good first kit =) silent yet powerfull..

Out, that sounds scary..it's good that it was Your bottom rad =) how did You notice?

P.S. That copper rad is impressive! You still keep same OC at those temps?
