Maybe, there's also a chance this is their lowest end EPYC chip, because that's the power of EPYC, even the cheapest version still has 2TB RAM support and 128 PCIe available. Which makes it great for those types of systems where 95% of the work is done with GPUs.

Have you tried to undervolt the CPU? that can have big impact on temperatures, also the ambient temperature inside the case can make a big difference.

Hi everyone, Sorry about the lack of updates, I've been busy with the new design and getting my BOM and pricing complete. I'm close to final but you will have the bear with me for a little longer For now all I can show you is a small teaser of the new design.

Another bump, I do appreciate any input, especially from some CLC coolers.

Aha, you have and actual Nvidia reference cooler. I do believe as mentioned before that the PCB is the same as the Nvidia reference GTX980. http://configurator.ekwb.com/step1_complist?gpu_gpus=1632 This shows the Nvidia GTX 970 reference card needs a GTX 980 waterblock.

*Small bump*

You have a reference GTX 970? That means the Blower design one, The fan of this GPU sticks out over the PCB, the actual PCB is much shorter. If you have a reference design it should like something like this

Even easier https://shop.ekwb.com/ek-fc970-gtx-nickel EK-FC970 GTX is a high performance full-cover water block for nVidia reference (NVA-P2004) design GeForce GTX 970 series graphics cards.

Thanks @Janne nice temperatures, as to be expected of the EK Supremacy EVO.

I've got a small request from my fellow forum members. I'm working on a project that involves both a Custom GPU and CPU waterblock. I've already made the prototype and although I'm super happy about the performance of the GPU waterblock I'm not quite sure if the CPU waterblock is up to par. I'm looking for as much data about Idle and Load temperatures of Haswell processors that are liquid-cooled and running at stock settings. It seems I can find lots of information about overclocked CPU temperatures or "this doesn't seem right" CPU temperatures but I can't compare against those. If you have the time to run a quick test for me and post your findings I would greatly appreciate it. Important! Only Haswell CPUs and only at Stock frequency and voltages. CPU Stresstest: Prime 95 V28.5 Run Prime 95 set to Small FFTs for 10 minutes to make sure you have hit a stable temperature. Note: Prime 95 v28 uses AVX, this causes a much higher load/temperatures on the CPU that any game can achieve, however at stock settings and with liquid-cooling this test shouldn't be a problem to run. CPU Voltage en Temperature: HWMonitor You can use any program you'd like to take the CPU voltage and CPU temperatures but HWMonitor is a good option if you don't have one. Please fill in the following information CPU: Load Voltage: Waterblock/AIO: Idle Temperature: Load Temperature: Delta(Load-Idle): Example CPU: Core i5-4670 Load Voltage: 1.01V Waterblock/AIO: Corsair H100 Idle Temperature: 35C Load Temperature: 70C Delta(Load-Idle): 35C Thank you for participating Also if you are interested what the project is please have a look at [build Log] H2O-Micro (<3 Liter watercooled gaming system)

I've done the following to dual boot both the motherboard and the HDPlex Using the sata connector on the motherboard I take the 5V and soldered it to the GATE a simple MOSFET. I've then soldered it the Source to PS_ON and the Drain to Ground. So like this I'm working some other stuff out, but once I've done that I'll update the first post.

In my current setup I've crimped a Molex Mini-Fit connector that plugs into the 2-Pin header on the motherboard, this connector to the 4-Pin input on the HDplex, In the new design the HDplex is no longer used. The HDplex is rated for 250W but with active cooling over the heatsink you can get up to 400W out of it.

I'm looking both into the Fury Nano and Fury X in terms of support, they should both fit inside the current chassis, I would need to design different blocks and for the Fury X a stronger adapter is needed. No promises but I will be checking both out.

It has to be a wallmounted version, they already have a deskstand version. I wonder how they are going to differentiate between similar designs. Some, like yours and mine, have some really similar designs.

You already have the shape, or what is the goal? I would draw a center point rectange and then use the arc tool to make the necessary curves. Edit: I'm assuming you are also using Autodesk Inventor going by the look of your screenshot so I made a quick tutorial

I use Autodesk Inventor for the drawings, it has to option to makes holes that are threaded, it doesn't physically model the threads, but the program knows it. The exploded view shows how to assemble it, so you push the Arm through the Base and then secure it from the back. The mounting plate is mounted to the wall and that you twist and lock the Base to the mounting plate. the magnets are there to prevent the Base from moving to freely. My renders are made using Autodesk 3ds max with VRay Edit: You design does have some similarities, but 1 thing to consider when design is material losses, if the design you have is 1 piece, imagine how much time it would take to mill and the amount of aluminum that gets wasted. Take the 3 maximum dimensions of your design and add at least 1cm for each dimensions, then multiple. That would be the raw chuck off aluminum needed for milling.

I've submitted my design as well. 2 Parts that are machined from Aluminum and 1 part that gets die stamped. It is a twist and lock design with 3 magnets that prevent the base from being to loose. Also with this design is should be easy for Silverstone to offer a shorter single headset mount an a longer double headset option. Only the arm needs to be changed.

I don't have any pictures/renders of how they are connected. I will make some this week. If you look at the picture below you can see in the top left I have 6 vias, I used the 2 biggest vias to connect a seperate 12V and GND to the PCB. The problem I had with the PCB is that I had 1 trace that was still linked to the 12V, that trace got burned out, the PCB still functions fine. Yes it is a custom PCB, there are a couple of risers available that fold over the motherboard, but I had some specific wishes as well as a very specific height requirement, so I made my own.

I've designed a custom Reservoir/Pump top that both the CPU and GPU waterblocks are screwed into, so once bolted together 3 Acetal parts make almost the entire loop. On the radiator needs to be connected with tubing.

Well part of my design was based on the fact that you don't need a lot of Rad to cool something. In fact the R295x has a board power of 500W, say 400W of GPU Heat and they only used a 120mm rad to get it all out. 12*12= 144cm^2*3.8= 561cm^3 of radiator volume for a 400W to 500W load 9.2*18.4= 169cm^2*2.8= 473cm^3 of radiator volume for a 250W(GTX970 + 4790K) to 350W ("390X" + 4790K). So maybe it can work of course there are fan differences and such. Asetek build aluminum rads, mine will be copper. They have Push & Pull with 120mm fans I have 2x92mm fan in Push OR Pull.

Hmmmm, perhaps there is going to be a possibilty to support a 390X in H2O-Micro? How extreme would it be to have the highest end single GPU be 17cm in length. Should be possible in theory, there is no space need for all the VRAM so the VRM can be more optimally placed. I'm really curious about the 390X now and it should be launched this quarter.

Now with animated GIFs!

A while back I mentioned some results I had gotten with my setup but I've decided to do a quick run with some games included so here we go. Firstly I ran an Idle test, nothing spectacular, I was streaming Youtube at the same time. Ambient was 21C, with the radiator temperature being 30C so about 9C higher than ambient. Fans where at their minimum speed. Power draw at the wall was about 48 Watts. Next up we have Prime95 on 3 Cores with Furmark on 1 Core, this proved to be the most stressfull scenario I could create and is by no means even remotely comparable to a normal load. Ambient was 21C, with the radiator temperature being 40C so about 19C higher than ambient, Fans where at full blast. Power draw at the wall was about 285 Watts. HWInfo64 results seem a little vague, de maximums for CPU temperature are hitting 99C, but the average is 88C, and looking at the current temperatures it jumps from 88C to 97C for 1 second and goes back down. I this image you can also see how I had my probes for measuring temperatures arranged. Next up I tested 2 games, Skyrim with +- 200 mods and Far Cry 3. Ambient was 21C, with the radiator temperature being 47C so about 26C higher than ambient, fans where around 70%. Here can see that H2O-Micro can be small and quiet when playing games. Power draw at the wall was about 233 Watts. So with only 50 Watts less power consumed than the Prime95/Furmark run and the radiator being 5C hotter, temperatures are excellent on both the CPU(76C MAX) and GPU(73C MAX) Ambient was 20C, with the radiator temperature being 46C so about 26C higher than ambient. Fans where at around 70% speed. Power draw at the wall was about 207 Watts. Again excellent temperatures and fan speeds while playing a game. I've also received some samples this week for the kit to check out and test. Among them a set of fans most of you will recognize instantly. But first! I orderded some Anti-vandal switches, Both are the same model and have a white led but 1 is a Dot and the other a Ring, let me know which you prefer. I already have a preference, can you tell? Switches in Off state Switches in On state I modeled the switch in CAD and pooped out a render. And finally I was sent 2 Noctua NF-A9x14 PWM fans by Noctua. These are actually my first Noctua's and I'm looking forward to testing them. I will be comparing them to some other manufacturers but they haven't arrived yet. Some of my models I download from a website called www.grabcad.com and someone on there already made some Noctua models, but not of the Noctua NF-A9x14 PWM. So I went ahead and made a CAD model and gave it a lick of paint in 3dsmax. I have to say I'm pretty proud of this model, it's 99% accurate. That was it for now.

Gainward should have 2 GTX970's that should be okay to use with the system. Their default Blower style and the Phantom version: http://www.gainward.com/main/vgapro.php?id=954〈=en http://www.gainward.com/main/vgapro.php?id=953〈=en Though I have to put a remark for the Phantom, it looks like they use the reference PCB but I'm not sure what TDP they have set for it. Other manufacturers are: Palit PNY

I've been getting more and more question about the final price for the kit, so I guess I'll go ahead and release an estimate. I'm still waiting on some small bits and pieces for final pricing, but the biggest wait is still the case. Also some other parts I haven't been able to calculate yet, because I still have to design them, such as the GPU power board. If I'd have to give an estimate I would say somewhere between €350 and €450 would be end user pricing. It will be an expensive kit, I realize that, but I think the pricing is justified looking at what the market has to offer and what you actually get. What do you actually get for that kind of money?
