EK Introduces EK-Pro Manifold for Even More GPUs

[GFreeman]

EK, the renowned manufacturer of premium PC water cooling equipment, introduces yet another addition to its Pro lineup: the EK-Pro Manifold 2CPU 8GPU - Acetal, a specialized coolant delivery system designed for use with a great multitude of water blocks in workstations and servers. Like the previous EK-Pro Manifold 2CPU 6GPU - Acetal, this manifold has all the perks of its smaller brother with compatibility for an extra two GPUs.

Efficient Cooling Distribution
The EK-Pro Manifold 2CPU 8GPU - Acetal redefines cooling precision with its impeccable coolant distribution. Featuring multiple industry-standard G1/4" In and Out ports, it guarantees optimal coolant flow, ensuring flawless cooling for both CPUs and GPUs. With the capacity to accommodate two CPUs and impressive eight-GPU configurations in parallel or semi-parallel, this high-performance manifold opens new horizons for liquid cooling in workstation and server environments.



Easy Interlinking with Manifolds
Manifolds, in the realm of custom water-cooling systems, are essential hardware blocks equipped with several standard G1/4 threaded ports. Traditionally, water-cooling loops direct coolant flow in series to each component consecutively, limiting cooling efficiency. Manifolds, on the other hand, split the coolant flow into as many outlets as needed, simplifying tube routing and saving time in systems with many cooling components.

Built to Last and Effortless Installation
The EK-Pro Manifold 2CPU 6GPU - Acetal boasts a robust construction, featuring a full acetal body, stainless steel end caps, and nickel-plated brass plugs. Delivered pre-assembled, it is ready for immediate use in a semi-parallel setup, providing reliability and efficiency for professional computing needs. The included universal mounting system ensures compatibility with various configuration scenarios. Equipped with 120 and 140 mm fan mounting patterns, the steel mounting plate seamlessly integrates into all computer cases, facilitating a hassle-free installation process.

Streamlined Expandability with Quick Disconnect Kits
For seamless scalability, it is recommended to pair the EK-Pro Manifold 2CPU 6GPU - Acetal with the EK-Pro CPU Quick Disconnect Kits and EK-Pro GPU Quick Disconnect Kits. This dynamic combination allows users to add or remove water blocks within their cooling loop without the need for a complete system drain, minimizing downtime and maximizing productivity.

Availability and Pricing
EK-Pro Manifold 2CPU 8GPU - Acetal is manufactured and assembled in Slovenia, Europe. It is available for pre-order through the EK Webshop and Partner Reseller Network. The product is expected to start shipping in late October 2023. The table below shows the manufacturer-suggested retail price (MSRP), VAT included.

EK-Pro Manifold 2CPU 8GPU - Acetal 219.90€ (MSRP inc. VAT)

Clean - Always impressed!

@GFreeman - Is it wrong to connect radiators to manifold like this to simply the setup?​

It's only wrong if it leaks

Do it up however you like. If it makes running your tubing easier why not?

Thank you—the next plan for a water loop. I want to simplify the system, connections, etc. I used one of the smaller manifolds, but it is only on the GPU/CPU. Then, I did not consider just using the extra connections for the RADs. It could have simplified the tubing in the current system.

Thanks

Well, you will of course loose some performance. Manifolds bifurcate and that means lower flow. On top of that, whatever kind of pump you plan to use, this maifold still eats G1/4 connecors, sou you're gonna bifurcate that to like what? 3? 4? 6? So if you want to compensate that, you will have to use more than one pump and connect them in parallel directly in the manifold. It can work, you just have to think it throught flow-wise. The block will suffer the most, because those have the most restriction.

If one gpu gets a little bit clogged up/impeded somehow, it will receive dramatically less flow right?

It's parallel flow so if the restrictions of each block/passage are not equal the water will as it always will, flow thru the least restrictive path.. so yes.

In my current system, I use the EK Dual D5 Serial Pump! - Amazing pump! This little joker runs almost on full tilt, and I never hear a peep out of the pump. This is one reason I learned that having extremely high flow in a system gained me better CPU/GPU cooling vs. ramping up the fan speed.

I considered, just for the heck of it, placing another RAD in the current system. And instead of tapping to the current coolant line; tap the rad right into the manifold.

High flow is not important in pc loops and after a certain flow its all wasted flow. Head pressure or static pressure is what is paramount. D5 have high flow and low head, but since you're running dual D5, you've doubled your head pressure. Two D5 roughly equals one DDC pump fyi... of course the D5 has a much better noise profile and it's internally cooled, aka dumps heat into loop so there are trade offs. If noise is high priority then D5 is the way. The trade offs are moire detailed like size, power, etc...

 

[HBSound]

So why are high flow and head pressure not one and the same? That is confusing. Also, I was under the impression that D5 pumps are better than DCC pumps. So you are sharing that the DCC pumps are ideal for good head pressure for the blocks? Is the DCC pump more noisy?

Hmm, neither one is better than the other imo and its down to preference. Flow and head pressure is not the same thing, and ppl often confuse the two. Being able to blow a lot of air thru a straw is like high flow. Now cap that straw with your finger and its a lot harder to blow thru, that is head pressure and the DDC is better when there is a restrictive load. That's the difference and to repeat DDC are much much better in cases of high restriction blocks, bar none. However they are louder, use a liil more power, dump heat into the air, but they are tiny. In most simple loops a single D5 is satisfactory as far as head pressure, so you can use a single D5 or DDC. It doesn't really matter so pick your poison. However in multi block setups which is pretty much dead these days, think quad SLI/CFX, DDC is the way to go. The testing and science behind has kind of been lost to time... lol.

Thanks for the info!
Solid info!

I have the 2CPU 2GPU EK-Pro manifold. https://www.ekwb.com/shop/ek-pro-manifold-2cpu-2gpu-acetal

With QDC connections it makes swapping out hardware simple.

And I am convinced the PC components EKWB makes for their server/workstation brand - Ekfluidworks. They are making it available for the public to purchase outside of those big systems. EK always made this manifold. It was always locked up in their rack mount server - pictured below. I remember speaking to EK; making some of those parts available to the public. Looks like they are letting them go one at a time.
