New Aquacomputer block: Cuplex XT Di - Double Impact

[Halk]

This concave/convex thing - whichever way it's supposed to be.

This is something fairly recent, and it's only showing a benefit with Intel CPUs, or is it also showing a benefit with the newer AMD IHSs as well?

Concave=VERY BAD. Convex bases are called BOWED bases, it allows for a lot of force to be applied in the center of the CPU, which gets better contact, which gets better temps. Concave means you'll have a thick region of thermal paste in the center and thermal paste has poor thermal conductivity so...

I don't think you understand that performance is affected by a lot of things. Its not just the barbs, the pump, the block, or the radiator. But as a whole, everything counts Now I don't know what you have but for the price of that aquacomputer stuff I think I can get a watercooling system that WILL perform 5C better or more than some aquacomputer thingy... :P Don't like the fat tubes? use 7/16", the OD is only a bit bigger than the 10mm OD tubes you have :P

Oh I do understand that. It's the whole thing together that affects things. It's the thermal paste, it's how well it's mounted, it's (apparently) what shape the waterblock is. It's how good the waterblock is. It's about getting the right mix of restrictive/non-restrictive blocks. It's about getting the tubing right, the whole thing together. I'm sure it's made up of 0.2 here, 1 degree there, maybe even 2 degrees here or there. But I was talking about tubing only.

As for AquaComputer blocks - I do not believe they are the best out there. For all anybody knows this new XT DI could be the best block ever made - I'd be surprised.

But as far as tubing goes I like the 8mm OD (not 10mm, even smaller than that!).

As for the 5 degrees? I'm going to have to ask you how you know that. If it's just a hunch then I guess we'll never find out. The amount of expense and time involved in properly finding out would be enormous.

But if you really do know something I don't about it, I'm very eager to read it.

Going back to where I said if I was to start again... I may not go for AquaComputer stuff. Lacking any further data I probably would go for their blocks. But if I found out there was a tangible difference between an 8mm OD AquaComputer setup, and some other setup with 8mm OD (I'd maybe go 10mm OD at a push) then I'd be seriously considering it.

Although the PC sits next to me, it's my toy, it does a lot of my recreational stuff. It stores all my music, it's my TV, it's the way I speak to my family overseas, it's the way I read the news, the way I send letters, it's where I play games, where I keep my :banana::banana::banana::banana:, etc etc. So, I suppose just like an expensive car, it isn't _all_ about performance. Looks come into it to, and I like the looks of the AquaComputer stuff.

But like I said I'm really all ears about the 5 degree difference. I've tried to read as much as I can on watercooling in general - I enjoy it. And specifically on AquaComputer stuff (although it's thin on the ground, and most of it is Ranker types stirring things up). So any information people happen to have to share, I'm going to read it

I wasn't trying to imply low flow did outperform high flow.

I wasn't accusing you of that. I just wanted to nip that argument in the bud before someone started expanding on it, since it was mentioned further up in this thread.

Yep, that much I understand. I just couldn't remember the concave/convex stuff, it's been over 15 years since school physics classes.

Essentially the additional force causes better contact between waterblock/IHS and IHS/thermal pad and thermal pad/core. Not exclusively because of the uneven surface of Intel IHSs, just because of the nature of IHSs themselves?

In that case would it not have a similar effect to have a much smaller contact area on a waterblock? Have the block the same size, but have a smaller, perhaps a bit bigger than a core sized area slightly raised on the surface of the block to create... ah, no it wouldn't. You would want a smooth transition between the center of the waterblock and the edges of it, so that there wasn't any areas which weren't in contact...

Am I getting the right end of the stick?

Fairy nuff Guess I didn't quite grasp that one right.

If anyone is wondering - I'm genuinely not trying to score points here or win any arguements, I am really just trying to learn as much as I can. It does sink in eventually, honest :P

[Grinch]

lord knows I learn something new on this forum everyday...*-)

[Halk]

Yeah, soon as I say I'm not looking for an arguement, and ask people to fill my head with learning.... everybody shuts up :P

[Grinch]

hahaha...*-)

[Aqua-Pc's]

thought you might like to see a few pic's as they arrived today








let the flamming begin

[serialk11r]

Hmm...looks like it may have some potential but crazy restriction. Looks pretty good, although I think they went overboard with the bling on the moutning plate :P

[lowfat]

sure a sexy little thing

[Top Nurse]

So what separates the water chambers? How about a pic of the accelerator plate bottom?

[1badhabit]

sure a sexy little thing

I concur.

[montyshaw]

Yeah, can we see a pic of the bottom of the acc plate? What keeps the water from just scooting across and out the outlet? What makes the water go back up and thru the 2nd jets? There would have to be something on the bottom of the jet plate to do that.

[Top Nurse]

Is this the G 1/8 or G 1/4 version?

[Cyprio]

Is this the G 1/8 or G 1/4 version?

Well they are selling the g1/4" on their site...

Also the pics here might help:

http://www.aqua-computer-systeme.de/e_forum-index.htm - go to the Wasserkühlungen forum and look for the Cuplex Di thread.

[montyshaw]

Thanks for the link Cyprio. Looks like there is a divider plate that directs the water through the middle of the base pins. I still don't see what would force it back up to the second jets. Maybe I'm not understanding it correctly.

Can't wait to see a comparison of this against the GTX and the Fuzion (maybe even with the new nozzles?)

]Monty[

[sick_g4m3r]

That base looks sick, but the restriction will keep it from competing.

When will there be any charts for it?

[RickCain]

We should see these in the USA (in G1/4) in the next week from what I understand.......

For the record, the top is nickel plated brass.

[RickCain]

You will see them at http://www.sharkacomputers.com

[RickCain]

Yeah, only downside is you pick which mount at the time of order. I wish they would start to include a universal mount.

[NaeKuh]

Cathar, you love how they butchered your Storm idea?

So what are you doing right now?? going DOE! i should of thought of this?

or you laughing in some corner reading your bike magazines?? :P


Also.... what stops the flow from going straight past the second chamber? If i remember fluid dynamics correctly, wouldnt the water just slide right under the second injector since it doesnt look segreigated, and then go staight to the outlet?

[RickCain]

have you had any experience with that type AC block compared to the FuZion or GTX? or know anyone that has a comparison, link etc.

On face value looks like a pretty decent design, as good as I've seen. I wonder if it has to be orientated a certain way over the CPU as to match the flow direction over the cores.

and thanks for the info and posts, helps a lot.

andyc

Have not yet as it has not landed in the USA.

[_G_]

looks like they just took there existing baseplate desing and slightly modified it to work with a redesinged upper block. Typical of German companies, slow incremental inprovements instead of higher risk new designs. It looks cool but Im intrested in how well it works.
