    Started a thread on SFFnet: Concept - Yet another 10L watercooled mini-ITX | SFF.Network (smallformfactor.net)

    Currently I have 3 designs I'm working on / considering:

    1) Cons(f)ol(d)e:
    • 10.8L with dual x8 slots via CPayne Riser
    • cooled by XT45 240mm and 25mm fans
    • using Nouvolo Aquanaut CPU block/pump and EK GPU block
    [​IMG]


    2) Thinny ITX Console:
    • 12L horizontal case
    • same hardware/cooling as above but different PCIe slot layoutvia CPayne Riser
    [​IMG]


    3) Zen of Chonk
    • 9.4L vertical case with same hardware as above but no PCIe slot bifurcation

    Trying to get started in Fusion360 but not sure whether the free maker version will allow export for laser/plasma cutting / folding etc...

    So I got a new toy…
    I’ll see how this goes as a block / pump. Considering 2 separate loops with 240mm or 280mm rads, or combined with single pump. I’ll find out if the LT pump can handle it, if not I’ll be ordering myself a Nouvolo Aquanaut!

    Hooked up the second loop now for some testing.

    0CA820CF-8B59-486D-AED3-6CED7043D733.jpeg

    CPU loop:
    GPU loop:
    Fan/Pump speeds auto-controlled by Rem0o's FanControl
    60 minutes of OCCT Power Test (CPU ~125W, GPU ~325W)
    LT pump ~90%, not audible over other noise
    D5 pump ~49%, not audible over other noise
    Fans ~49%, audible but not intrusive

    CPU hit max temp of approximately 81C
    GPU (hot spot) hit max temp of approximately 81C

    Idle for ~5min after test, CPU came down to ~40C (pump barely running) and GPU came down to ~28C (room is approx 24C)
    upload_2021-10-19_16-15-50.png

    With the fans and pumps both cranked they don't get anywhere near that warm with a full 60min test. (Closer to 65C each)

    I have noticed that the LT pump is only just barely perceptible (only if listening for it) at full speed, so maybe it's worth leaving it at 100%. Would improve both idle and load temps, but not sure to what extent.

    Next step is to try the single loop with the single XT45 radiator and only LT pump, see if it can manage the CPU/GPU heat. This would open up a lot of opportunities for the case design thanks to removing the separate reservoir/pump from the loop.

    If the LT pump is too weak for that loop, I'll order a Nouvolo Aquanaut (OG or extreme) and a DDC pump or maybe even a Barrow Block Pump and see if it's beefy enough.

    The genuine 18W DDC should be fine, as the performance is roughly equivalent to the D5, I'm unsure of the 10W Barrow pump's performance characteristics. Either way it removes the external pump/reservoir, but both are noticeably larger than the EisbaerLT.

    ::EDIT:: I take back my comment about the LT pump at 100%, it is actually audible now I turned off the A/C. There's a quiet but perceptible and annoying buzz from the pump at 100%, it's entirely possible there's still some air bubbles stuck in there.
    Interestingly the idle temp didn't actually drop much when the pump was dialled up, so maybe it's just the lower limit of the (slightly fucked up) carbonaut square sheet TIM and the coldplate design.

    Gonna try belting it about a bit and see if any bubbles come out :D

    After belting the block/pump a bit (while installed & running at 100%) I did see a few bubbles shoot from the outlet, idle temps down around 32C now. I've heard of people temporarily hooking up a reservoir and more powerful pump to help bleed the air out, but we'll see how we go for now.

    [X-post from SFFn]
    I've been working on two different versions of the vertical tower.

    One (ZenChonk L) with greater capacity for fat (but not ultra-long) GPUs and dual 240mm radiators. This would bring the volume up to 12.2L, and requires a PCIe riser, but it significantly expands compatibility and ease of installation, the other (ZenChonk S) with the smaller volume but only capable of taking the single radiator & single-slot W/C GPU.

    I've also been working on the mechanical attachment of panels, while keeping to mostly individual pieces for flat-pack shipping options. Haven't decided whether or not to keep the tri-fold cover plate (like the AT computers of old!) or move to separate side/top panels.

    ZEN CHONK L
    Dimensions as shown:
    Width 154.2 mm
    Height 312.2 mm (exc 15mm feet)
    Depth 253.6 mm
    Volume = 12.21 L (plus feet)

    [​IMG]

    [​IMG]

    ZEN CHONK S
    If I want to keep the volume/dimensions as small as possible, and restrict to single-slot, ~280mm GPU, and single 240x45mm radiator then I can get it down to approx 9.3L:

    Dimensions as shown:
    Width 162 mm
    Height 297.9 mm (exc 15mm feet)
    Depth 192.4 mm
    Volume = 9.3 L (plus feet)

    [​IMG]
    [​IMG]

    Test Setup
    I set up a roughly-equivalent, but open, layout to the ZenChonk S (although I accidentally placed the rad the wrong way around so the PSU can't currently fit behind the rad where it should) and tested it. The tubing you can see off the EK 45deg fitting is a makeshift reservoir. This allowed me to bleed the air out, after which I drained the res-tube and fitting, and capped off at the T-fitting.

    You can see the Corsair SFX PSU behind Grumpy Bear's head, the rad is sitting atop the backplated GPU and the motherboard is slid onto the GPU via the PCIe slot. Thin foam sits underneath the GPU and between the rad/GPU which keeps things relatively stable. I wouldn't want to leave it like this permanently, but it's secure enough that I could (carefully) pick up the whole rig and turn/shake it to help bleed out the remaining air.

    [​IMG]

    Thermal Testing:
    I have determined that the single-loop with Eisbaer LT & 240mm XT45 is sufficient to cool CPU & GPU if not heavily overclocking. A 1-hour OCCT run had both peaking around 80C with about 115W + 292W according to HWInfo64.

    At regular usage it's completely inaudible, and even when pushing hard it's not an obnoxious sound profile, thanks to the 2x120mm Air Blazers which are surprisingly tolerable sounding fans even at 100% rpm.

    Will do some further thermal/noise tests later, and continue with planning the case design(s).

    [X-post from SFFn - reply to mirinjesse Q about hardware]
    Using a (terrible-sample) 5600X and a reference 6800 XT.

    Bear in mind that 80C result is peak temperature (CPU die & GPU hotspot) over a full hour of both CPU & GPU at maximum power/heat with OCCT, it would not be representative of benching, mining or gaming but the absolute worst case scenario.

    Also the carbonaut pad on the CPU is looking a bit ratshit so would probably do better with some decent paste.

    As above though, I’m considering a dual radiator version but it’ll come down to personal preference whether people want smallest size while still being quiet, or larger but better cooling.

    ::EDIT::
    I think getting the EK rotary terminal or Angled terminal for the GPU waterblock has got to help with the layout. Though it would mean losing the ARGB 'RADEON' logo terminal cover.

    Definitely need to put the radiator the correct way around per the design [facepalm moment]

    Internal frame design update

    upload_2021-10-25_12-46-21.png

    Might need to be the XL version though... although 11.6L is pretty tidy for dual 240mm radiators...

    Significant update to sub-10L version “Zen of Chonk S”, seeking feedback and suggestions on this design as I feel it’s close to ready for manufacturing.

    Dimensions as shown:
    Width 163 mm
    Depth 195 mm
    Height 298 mm
    Volume = ~ 9.5L

    Full imgur album shows expected assembly process.

    Keep in mind I still need to plan and place the specific fasteners & screw holes, but the layout and shape of the structure should be about right.

    It looks fantastic and I love it but I'd never buy it. I wouldn't trust that I wouldn't have to open it back up and that looks painful to do.

    I’m investigating a way to service it easily, maybe using a hinged rad panel and rotary fittings. Haven’t figured it out yet though :)

    I've done some minor re-work, including adding all the various fasteners required (a lot), Fusion360 renders of the Sketchup file.

    Prior to manufacture I'll need to re-do the model itself in something CAD/CNC-friendly.

    Dimensions remain the same:

    Mate keep it coming, im hell keen on this, I recently just brough a N200P for my mobile needs but the heat off a 5900x is proving to be interesting to handle with a single 280.

    Current Competitors

    Current competitors (thanks to CaseEnd) are listed below. The most readily-available of these alternatives are probably the SSUPD Meshlicious and ZS ST v1. Other 240mm-supporting cases include the Geeek A70 Pro, Sliger SV540 and Winter One. The latter 2 obviously being boutique designs, so harder to source (and more expensive). The Geeek A70 Pro is new to me, looks like some sort of Meshlicious clone attempt?

    To SFF makers/vendors: Are you producing/selling/designing a vertical case that I haven't listed? Please let me know !
    • Have I missed any others currently on the market (or prototyping)?
    • Are there other cases that are regularly modded to fit in with this lot? (Vertical orientation / 240mm rad / full length GPU / SFX power supply)
    • What does the competition offer that you'd like to see? What are the most important differentiators in these cases?

    Want a 280mm radiator? Ok, that's just 28mm taller :)

    Redesigned the radiator bracket and sidepanel vents for 240/280mm radiators:
    upload_2021-11-10_23-22-44.png upload_2021-11-10_23-26-18.png

    ::EDIT:: Minor update to rad/fan hole spacing, as not all 280mm rads use 15mm space between fans.

    ZoC-S got the same rad-bracket update (sans 280mm mounts because the case is slightly too small)

    Trying a new layout using a reversed right-angle riser (GPU over motherboard), imgur album shows the layout if installed horizontally, but would eventually be used vertically (IO down).

    https://imgur.com/a/8yGRrBt

    This should reduce the minimum depth significantly but sadly doesn’t change the minimum height.

    Width will depend on radiator mounting location, ie whether I mount it at the ‘top’ of motherboard or somewhere else.

    So slight change in direction here, I've ordered a few new parts, and I'm hoping they'll arrive before Christmas but we'll see.

    Here's a little teaser for what's to come...
