EK-D5 Dual TOP

[millertime359]

u mean when skinnee mails me my pair.

And i was gonna get a T3, but i dont have my D5's yet.

Also i got discouraged when a lot of T3 owners started reporting cracking. :\

But i have 2 D5's im not using. I might as well put them to use no?

Yea, hope the new manufacturing place and the change to ABS will fix those issues.

[bentleya]

^^
I believe that u were using a rad in your loop...

Scaniris didn't use any, which isn't a wise thing to do on the first place, heated up water like hell so tube went off...

In this loop yes.

Don't ever test pumps without a rad m8 for prolonged time. Eventually u'll burn them due to excessive heat...

What?, i've had a DDC pumping EC6 around the tubing rig for 2 months non stop. Still works.

u are... cuz now u only have 1 left after u give me my 2 i sent you.

I MIGHT play with this top, and swap out a dual ddc for dual D5's on my gpu loop for the hell of it.



Get clamps on.

Dont be rambo, trust me on this bentleya, u know ive ran into almost every problem one can possibly run into in our hobby.
And at the very least i always used zipties.

It's just one of them things, i keep changing. I did have, then i got a new GPU to play with so had to re do loop. But i will eventually put clamps on, well zip ties.

[Scaniris]

not to sound mean..

but i think i would of gone DDC's and kept everything internal.

:X

But u have a nice setup, a bit hectic inside, but a nice setup.

If I knew some monthes ago that I'll upgrade my air cooling system with a water cooling system, I had probably choosen the X2000 chassis instead of the X500 ^^ But for the moment I'm experiencing lots of new stuffs for me, and I'll probably change my chassis later on. I'm also intersted in chilling... so until I've defined the cooling concept, I'll continue to experiment in my small lab Yeah for sure it's not sexy, I know that, but I make some experiences changing my hardware each 2-3 monthes to learn and make my own experience. ^^ And select components after reviewing them myself, I like reviews on internet but I prefer to test @ home.

Why DDC instead of D5? More pressure and less flow is that really better for such a setup? I'd really like to get some details

Our setups have high restriction that means in the end the resultant flow will be higher with a DDC. We can counter that by running parallel lines from a D5 (with a T3 res for instance). Also the DDC is square (easier to integrate in a typical PC case), and a lot smaller than the D5.

[Scaniris]

Thanks for the information. The flow rate that I provide here comes from a flow sensor at the end of the loop, this is the flow speed at the end of the loop, not at the output of the pumps. The resultant flow.

400l/h as resultant flow rate it seems to be great but you think that i can increase this flow speed with a dual DDC? What would be the benefit? Temp decrease?

For ergonomy you are right yeah... D5 are not really small. Do you think it could be interesting for me to purchase a dual DD with top? If there is some upgrade inside for my system, I can order it no problem, I just want to know what will be the benefit of higher flow rate.

because u could tuck them in tighter spots, and not have the pump unit outside.

dual ddc packages are a lot smaller then dual d5's

[Scaniris]

If I change my chassis from a mid tower to a big tower, no problem anymore with that. With this Lian Li X500 chassis I have to put everything outside, also the rads so if i change my chassis I'll take a larger one where I can put 360 and 240 rads inside.

My question is more about performance, I mean what's the benefit of a Dual DDC Plus package versus a Dual D5 package? Except the form factor? I see that you have a lot of experience with Laing pumps, and I need your expertise I also have a question about chilling: bot D5 and DDC pumps are certified for waterchilling? I mean if I add a chilling unit, may I use D5 or DD pumps with dual top or are there any restrictions for that? (beginner inside )

There's maybe a topic on the forum comparing dual DDC versus dual D5? I did not found that's why I'm asking the question If there's not and if there are some arguments about performance coming from your side for a DDC upgrade from D5, I can order 2x DDC Pumps with a Dual Top (which one?) and compare with my current setup! And yeah... one of my inline temp sensor is dead (my fault... broken cable) so I'll have to change it and at the same time I can compare pumps if really useful.

I mean even if I change my chassis, I want to keep this loop layout dual pump > CPU Waterblock > rad 240 > GPU waterblock > rad 480 (or 360 depending on chassis features) > res > dual pump. One loop. Maybe two why not this is only a question of connecting tubes. And before choosing the new chassis, I have to fix my strategy I mean pump model, chilling or not chilling etc... to make sure not having integration issues.

[Scaniris]

The dual top for DDC pumps you were talking about some pages before, is that this one http://www.watercool.de/online-shop/ or this one http://shop.aquacomputer.de/product_...oducts_id=2359 ?

If you flow really is as you say (basically 1.75 G/m) then you will not see any improvement by getting DDC pumps.

[NaeKuh]

u wont see any noticible difference between ddc's and d5's.

The noticible difference tho is the size package.

D5's are big, x2 thats a lot of space.

While as a DDC x 2 on a dual top package is not very big at all.
Theres even front bay dual ddc units.

In your build, i think i would of removed the DVD writter, got an external, move the LCD unit somewhere else, and put in a bay res / dual ddc unit there.

[Scaniris]

Thank you for your answers

Yeah the flow rate is 400L/hour at the end of the loop:

400 liter / hour = 105.668821 US gallons / hour
6,66 liter / hour = 1,76 US gallons / minute

Loop is configured as described:

D5+D5+Dual Top > Waterblock CPU (Watercool Heatkiller Rev 3 copper) > Radiator 240 (Feser Changer) > Waterblock GPU (EKWB FC-HD5970) > Inline Temp sensor High flow > Radiator 480 (HWlabs Black Ice SR1) > Inline Temp sensor High Flow > Flow meter High Flow > Reservoir > D5+D5...

I hop that like this I get the lowest flow rate, I suppose that I'll get higher results if I put the flow meter between pumps output and CPU Waterblock. The measurement I have now is probably the lowest number.

Well I clearly understand that the main benefit would be the size.

@ NaeKuh: the LCD display is the Aquaero controller, behind this display I have more than 14 cables....(6x thermal sensors, 4x fan power with splitters, 1x flow sensor, 1x molex, 1x emergency power switch, 1x standby power connector, 1x usb cable...). I can remove it from the chassis. But as said I prefer to change my chassis for another one, bigger, where I can mount the radiators (like a Corsair, a LX2000, etc...). But I'll see that later on, for the moment I'm in the testing time, and I try different producs to define what i want to keep and what I want to dismiss ^^

Here a short description of this controller : http://www.sidewindercomputers.com/aq4usbfawh.html
And here a topic in the forum: http://www.xtremesystems.org/forums/...d.php?t=227106

Flow rate is constant through the loop. It will read the same no matter where you put the meter. Pressure is a different matter all together, each component robs a little bit of the available pressure.

[Scaniris]

Thank you It will help for my next build!

Hello,

Here is the photo selection, part 1

Photo 1: jumper to start the ATX power without Mobo. Safe to test a wc loop.
Photo 2: the flow sensor
Photo 3 & 4 : testing setup 1 overview, 1x D5
Photo 5 : back of the D5 for 1st measure @ S1

[Scaniris]

Here is the photo selection, part 2

Photo 1 : flow rate @ S1
Photo 2 : back of the D5 @ S5
Photo 3 : flow rate @ S5
Photo 4 & 5: test setup 2 with 2x D5

[Scaniris]

Here is the photo selection, part 3

Photo 1: back of D5 pumps @ S1
Photo 2: flow rate @ S1
Photo 3: back of D5 pumps @ S4
Photo 4 : flow rate @ S4
Photo 5 : back of D5 @ S5

[Scaniris]

Here is the photo selection, part 4

Photo 1: flow rate with pumps @ S5 (remember that you have to add 650 + 71,43 to have the real flow rate, see my review some posts before)
Photo 2: cyclon appears when both pumps are running @ S5, not before
Photo 3: Dual D5 with EKWB dual top and 60mm reservoir with LINK and Top
Photo 4: Dual D5 with top setup overview
Photo 5: flow rate @ S1

[Scaniris]

Here is the photo selection, part 5

Photo 1 : Flow Rate with Dual D5 + Dual Top + Res 60mm @ S2
Photo 2 : Flow Rate with Dual D5 + Dual Top + Res 60mm @ S3
Photo 3 : Flow Rate with Dual D5 + Dual Top + Res 60mm @ S4
Photo 4 : Flow Rate with Dual D5 + Dual Top + Res 60mm @ S5
Photo 5 : reservoir until S3 speed, no cyclon, no disturbances

[Scaniris]

Here is the photo selection, part 6

Photo 1 : 60mm tube on Dual Top @ S4 speed, some air appears
Photo 2: 60mm tube on Dual Top @ S5. more air bubbles but no cyclon
Photo 3 & 4: anti cyclon component placed into the tube
Photo 5 : tube with anti cyclon option @ S5... same result with or without the anti cyclon option

[Scaniris]

Here is the photo selection, part 7

Photo 1: some vapor appears between the fitting and the tube, it's not hot but probably around 28°C or something. As explained, I use this tubing ONLY for testing or cleaning purposes, otherwise I use 12mm tube, no need for clamps (have a look on the ''productive'' system later on)
Photo 2: 60mm tube on the Dual Top @ S5 after 10 minutes... less air bubbles..
Photo 3: 100mm tube on the Dual Top @ S4 after 1 minute..
Photo 4 : 100mm tube on the Dual Top @ S5 after 10 minutes... no cyclon..
Photo 5 : same thing @ S5 but with less distilled water... no cyclon @ more than 700 liter / hour... in a standard loop I get 400l / hour so it's impossible to get cyclonic effect with this setup...

[Scaniris]

And the final tsunami ^^ nothing really wrong because it's only distilled water and not the coolant I use for my system, and I was lucky because the tsunami did not reach the interior of the case!!

[Scaniris]

And finally the ''production' realeased setup in my system with Feser F1 coolant transparent:

[Sadasius]

Thanks for all that Scaniris. Much appreciated.

[Edward88]

Nice performance.


I really would like to see this top vs xspc dual ddc top.

Thats the fight

[meanmoe]

@Scaniris

Nice man. How tall is the whole setup with the 100mm res on top?

I was running a T3, but it turned my case into a swamp and right now primochill isn't checking their emails. I need a replacement now and I'm thinkin' about this as the extreme option.

I wish the ddc version was available here, I have a couple of them laying around already.
