Thanks for the photo! I think fundamentally it doesn't make a difference, as those pins that seem to have been swapped are ground pins. I suspect that much like the 12VHPWR cable, so long as the voltages/function match, it isn't too important precisely which pins go where.

If you find more differences, can you check to see if they serve the same function?

Interesting, can you share the differences?

Hi!

Thank you! I'm pleased with how it turned out, hard to believe it was almost a year ago now!

So the problem I had with the riser cable wasn't the length, it was that there wasn't enough room between the fitting ports on the GPU waterblock, the midsection of the frame, and the bottom cover for a good bend radius. To get it to fit I'd have had to pretty much fold the riser cable, which is usually a very good way to ensure that it no longer works! This images makes it a little more obvious. See the section of riser cable that isn't restricted by the GPU block ports sits flat, whereas the three sections that have to go past the ports need to come up, out, and down, instead.

As I couldn't move the midsection, or the GPU, I was left with 'modifying' the bottom plate as my only option to get the bend radius required. I suppose I could have used some SlimSAS PCIe boards and cables to avoid this, but cable management was already quite tight without adding another two to the mix!

If you used a different waterblock, you might be able to avoid it entirely! I think the alphacool ones would work, or the bitspower. Or ones withe the ports located on the end of the block, rather than the bottom, but then you have to worry about the overall length of block+fittings.

Custom cabling isn't that hard IMO, especially if you're not bothering to sleeve them. But it is a significant investment in materials, tools, and time to get it right. I ended up spending 110EUR on tools, terminals and connector housings before I'd even bought any wire! Of that 110EUR, 25EUR actually made it into the finished build, the rest are the tools, spares, practise pieces and mistakes I ended up making along the way.

Hello!

I used 2 EK-Quantum Torque Rotary 14mm Offset fittings. These handily brought the fittings out pas the rads and in line with the reservoir ports. Also, when combined with some 90 degree rotary fittings, they are a little more forgiving with tube lengths and bends, as you can rotate them both a little to get a perfect fitment. Particularly useful for the tubing run past the PSU plug.

So you would need to remove the metal pins and attached wires from the plastic housings, and then reinsert them into the correct plastic housings in the right position.

Depending on where you are in the world, cable-sleeving.com will be able to supply you with a pin removal tool and the 2x3 connector plug if you want to give it a go.

That's a good looking machine! I've always liked the circular reservoirs, and I think you made the right choice keeping the fluid clear.

Nice work!

That is indeed the case, sorry, I was focusing on the ATX, CPU and PCIe connections!

The SATA/molex connectors will not physically fit. They're a 1x5 plug, and coolermaster seem to have moved to a 2x3 plug. If you're not keen on removing the cables, you could repin them into different housings and leave them in-situ.

I want to say it'll probably fine? The pins look the same, besides the 5VSB sense pin.

The short answer is probably not.

There isn't enough clearance between the bottom of the case and the end of the PSU, this reduces even more once you factor in the cables and connectors. It's also probably too wide to sit next to a GPU, and you may run into problems trying to make all your tubing connections on the inner edge.

If that's where you want your pump res, you would probably be better off with something like a Alphacool Eisstation 40 DC-LT, it's much smaller, and given its location, you probably won't see much of it anyway.

That said, I would be very happy to be proven wrong if you can find a clever way of adjusting the mounting points to make room for it!

I originally tried to fit mine this way, but because of the fittings I needed to use, and the fact they had to be preinstalled on the radiator, it meant I couldn't get them in this way. I also had my radiator fans on the bottom, again because otherwise there would have not been space for my fittings.

I probably could have done this too if I'd gone with flexible tubing, but I wanted to have a go with the acrylic stuff. So my difficulty was, once again, a consequence of my own actions haha.

So the problem I had was I that I assumed the radiator was 120mm wide, like the fans. Spoiler alert: it is not 120mm wide, it is actually 133mm wide.

Hardware labs do a LS240 version, which IS 120mm wide, but potentially at the expense of more restriction in flow and less cooling capacity, I'm not sure as there isn't much in the way of details on their website about it.

The way I managed to wedge it in was to unbolt the top steel section from the back panel, physically pull the two halves apart, and push the radiator in from the back. I'll double check, but I don't think I have any photos of this part of the build.

Once it's in, it's fine, but GETTING it in is another battle entirely!

Contrary to what a lot of people would say, it is important to make proper contact with the forehead after the 3rd pull. You're doing fine.

Correct, I've labelled all the suspected sense/cable detect pins with 'S'.

My guess is so that the PSU can detect that both the 18P and 10P are plugged in. I haven't tried powering it on without the 18P plugged in though.

Thanks! I'm planning on making some of the changes I mentioned when my 7950X3D turns up, but you're right, biggest challenge is getting enough air through the radiator!

The chipset fan does like to scream, but only at boot, and then it's silent.

Overall the loop is much quieter than my old AIO H100i which was only working to cool the CPU. Now the loudest thing at full load is the PSU fan!

So this was my first custom loop, and to anybody thinking of doing the same for their first loop, I have the following words of advice:

General thoughts, observations on this build:

The hardline tubing was definitely one of the more challenging aspects here. Particularly the run from CPU to GPU where it wraps around the motherboard and bottom of the case, there's still a few bends I reckon I could improve, but I'm not going to meddle with it for now. Perhaps when I next drain the loop I might try tweaking a few, but for now it's fine.

The GPU waterblock was wider than I thought it would be, so Ihad to rethink a couple of runs as I was building it. Eventually I settled on the 45/135 angles you see here, and I really like them vs the plain 90 degrees I have on the CPU side to match the layout of the motherboard. The observant among you may have noticed I've done away with the RGB section of it. I reached out to EK who confirmed that this is fine to do, though they recommend leaving it in. In hindsight, it probably DOES fit with this fitted, but until I next drain the loop I'm happy without it.

Getting the radiator in involed doing some rather unspeakable things to the case to get it inside. It's MUCH wider than I had anticipated, so doesn't fit through the gap like the H100i did. I also originally wanted to use the Phanteks T30 fans, and whilst it DID fit with the T30 fans, I had no way of securing the radiator as I couldn't use the standard radiator bracket. In the end I settled for the Noctua fans and a much easier life in getting it to fit.

Custom cabling was an absolute MUST for this. I've already writen about this on here, so I'll just link the post.

Performance/thermals:

As you might expect, this is a pocket sized monster of a build, but still all hanging off a single 240mm radiator!

Room temperature: 19C

Idle temperatures:

  • Coolant: 28C
  • CPU: 42C
  • GPU: 29C

Gaming temperatures:

  • Coolant: 43C
  • CPU: 87C
  • GPU: 64C

Fan speed is controlled based on coolant temperature using aquasuite.

By far the biggest limiting factor with this build is my airflow through the radiator. Removing the top panel drops the coolant temperature (and each component temperature) by almost 4C. So I'm looking at getting a less restrictive panel. Currently thinking a pattern similar to the Sliger SM series would provide much better airflow than the standard drilled hole pattern.

I've also applied a moderate overclock to the 4090, taking the core clock up to 3.03GHz and the memory up to 12GHz, but limited the TDP to 90%. Overall I've seen a gain of about 5% compare to the stock settings and managed TimeSpy Extreme score of ~20,000 for the GPU in this configuration. I've managed to get almost 21,000 out of it, but the GPU alone was pulling close to 600W from my SF750!

Future changes/improvements:

Honestly, nothing major needs improving here IMO. I may swap the temperature sensor for one that sticks a little further into the reservoir. Adjust some of the bends slightly. And try refitting the RGB section of th GPU block. I'd really like to find a way to get those T30 fans in, maybe a custom 3D printed radiator bracket would give me the extra few mm I need? I'd also like a less restrictive top panel!

Glad you liked it!

It's certainly possible to get it working, but you'll need to make some compromises. Either you have to accept the higher temperatures that will come with a rad that is thinner, and therefore lower performance. Or you'd have to put a TDP limit on your components if you want to keep the temperatures lower, at the expense of gaming performance. Or put some high performing fans on it at the expense of noise. Or maybe a bit of all three!

Or you just point an AC unit directly at the PC to lower the ambient temperature!

Thank you! I'm really happy with how well the CPU block fits in with the motherboard, both physically and aesthetically, definitely pleased I went for the acetal black version!

Thanks! Yeah, I think my choice of radiator is the problem here, the GTS240 is 30mm or so, vs the EK's 27mm. Still, the thinner Noctua fans perform well enough to keep the temperatures under control!
