Best dual top (serial) for Liang ddc

Hi guys !
I got the problem of selecting a double top (serial) for pumps swiftech 350. Is present in the market quite a few options, but none of the normal testing.
The only test that I found shows only the flow rate but not the pressure in the circuit.

My choice is tops among the following:
Aquacomputer aquacover dual DDC, top for Laing- and Swiftech pumps, G1/4
Watercool Dual DDC-Case LT Acryl
EK Water Blocks EK-DDC Dual TOP V.2 G1/4 - Black Acetal
XSPC Laing Dual DDC Acryl top
My main priority is performance, and noise level (and vibration).
Most of all I like aquacomputer for connection variability in the contour. But based on the existing test, it is the weakest performance (a test in German, about the noise I can not say anything:))
Top EK is the most expensive, but there is no test data and its performance can only guess. A big plus Ek top decoupling kit.
In general I am confused what to choose.
I would appreciate any help in this matter.
p.s. And more interested in how you can reduce the noise level of the two pumps, is there a ready solution.

i would choose EK Dual V2 for better performance and Res placement .

Great thanks!
It help ! :)

i hold the best dual ddc package.. :P
Cuz it doubles as a weapon... imagine getting hit by that!
(getting ready for my 2012 zombie appocolypse)

unfortunately both the top and the DDC-2's are not available anymore :P

Serious note... id go with the EK as well, it has nice options is side by side, unless u want a bay res.

hmm, it's nice thing. do you make videos how its work?

I repeat the question here (maybe someone from the owners will be able to answer):

I had one question about Ek dual top v2. How about noise and vibration? Did it be very noisily in case i instal it in 5.25 slot with "M4 Antivibration KIT for 5,25" BAY mount" from Ek ?

The top? its the only top ever made which has 2 inlets and 1 outlet for the DDC.

As for performance... i dont know... id say its probably less or equal to the EK which is why i typically recomend the eK dual top for today's DDC.

Big difference tho, mine uses ddc-2, which arent made anymore... your lucky to find a new one... its almost like hitting the lottery.

As for performance.... ummm... my system probably still holds LC performance crown on this board... unless u want to start listing other systems that uses 6 pumps in total on 3 independent loops on 4 radiators. (4 ddc + 2 d5)

Totally dependent on the case your running bro.
DDC's vibrate.. its a spinning impeller so of course its going to vibrate... and when you have 2 spinning almost the same RPM's the noise and vibration levels double.
So its completely up to the case and your absorbing material..

Answering the OP, not Naekuh's detour.... My personal preference (use and performance) for dual DDC tops would be the EK and maybe the Watercool if the EK was already in use around the lab.

I use the Heatkiller and two MCP355's on it can make some noise, but I dial them back and cannot hear them. Unless you have an uber restrictive system, flow is over rated anymore. I run my two pumps at low voltage, enough to get .56Gpm and my delta between water and air temp is two degrees, maybe three. Mainly because I have three Thermochill PA120.3 rads which is more than enough to cool my 2600K OC'd to 4.8hz and my HD6990. It's not always about flow in my opinion. The only reason I run two pumps is for peace of mind.

Thanks NaeKuh, skinnee, Utnorris !
Ek looks best to me too. And if Ek mount will help struggle with vibration it be great. I had a Cooler master cosmos S which I plan to replace on Xigmatek elysium. My future cooling loop is be simple. Mora 3 9x120+ xspc rasa + ek 6970 fullcover+ swiftech 350+ swiftech 350/liang dc 12w(diyhnk) (i dont bought second pump yet). Later i maybe buy second 6970+ek full cover and control panel with flow metr.
But AC dual top looks well too to me, because have many variation of connections. In some loops it may be very useful. But perfomance ...

I have used the xspc dual top with Laing 3.25 for the past two years. It is a demon!
