For now, mine is sitting upright with a 14x14 mesh filter, there is a bit of gap due to the rubber foot, so I will probably remove the rubber foot at some stage, the plan is to get one of these FlyDigi BS2 cooler and sit two of the ASUS GX10 on top. Cooler has a temp sensing via BLE, and I’ve put together a python code that does the same thing as their “windows” app, i.e. monitor temp and auto-adjust the fan speed. Not yet tested on the DGX yet.. The Flydigi BS1 works pretty well on my Dell Precision Laptop with RTX5000, so I’m hopeful.
I refactored my design so its a little less boxy / more refined. Same design concept but slopes backwards from the rear of the DGX spark. I also reduced the wall thickness to 2mm so it prints faster.
Step and stl files for printing or modding further.

To everyone stacking your units side by side I’d say take a second and feel the heat coming from the sides of units, mine get positively toasty. I’d give them some space, I think someone posted a spacing image , they definitely need some room to breathe, if possible
Do you find an actual difference in the setup though? There’s less resistance for that fan pulling from the free air then pulling from within the unit. All it would be doing is exhausting air that’s already exhausted?
Sorry honestly I’m just so busy these days I would not have time but if you just search on Alibaba there’s many 3D printer suppliers and you can just download my file for free
So the design is doing two things, drawing considerably more air flow through the unit, and exhausting it away from the rear of the unit.
Without it, when I put my hand behind the unit the air is hot, the cable area is hot, and the unit gets worryingly hot to touch under load.
With the extraction fan, if I place my hand at the front of the unit I can feel the air flow being drawn into it. The back of the unit (cable area) is cool, the air is ejected up and away. Under heavy loads the case gets mildly warm but not hot like it used to. The rest of the time its cold.
Occasionally I might need to vacuum dust from the front grill. Looking at some kind of filter maybe.
Thank you so much for building this design. I’m no 3d modeler so I’m hoping you’ll do a little more work for some people on the internet.
- The spacing for the systems is exactly sized for a Spark or Spark clone case with the tapered base (Acer, Dell, Gigabyte, Lenovo). However, this does not work with the Asus or HP which has a slightly different case design. Can you adjust the design so that is has 51mm height?
- The center fan hub ‘bar’ makes this quite difficult to print without a lots of supports for FDM. Could you omit that bar, it’s probably better for airflow anyway. The squared, X design on top/bottom is quite difficult to print vertically, maybe a hexagon pattern.
- Please make a variant for 10 inch mini racks. You should be able to fit this into a 3U 10 in mini rack.
Here is a simplified version of the OP. Each GB10 rests on the side rails, not the pad on the bottom. 170 wide and 125 high, so it will fit in a 133mm 3U rack space with 8mm to spare. The 120mm fan is pushed in from the back. You could add a grill or filter to the front.

You can print this on a 200 x 200 x 200 FDM bed in one go with no supports. Its 190mm deep.
This is great! What I would say having the bar across the middle is going to be important so you can maintain pressure. Otherwise you’ll be losing some air flow between the two units that was my original concern with the rear exhaust design because the rear exhausts is open to open air it will naturally pull from that rather than from the unit so while the cables at the back are cooler because of that ambient air the effect on the inside of the unit might not be that much compared if you were to seal it and force all of the air through the unit
I should have looked at the Asus, for some reason I thought it had the same bottom as the Gigabyte (which we also have) – but its very different. This version doesn’t assume the rail/foot offset like the DGX Spark has.

Its very easy for me to make changes just draw what you want and I can add it to the design.
Do you know if the MSI Edgexpert fits (not that mine has any temperature issues), just out of interest.
From your description I think this is what you are after.

So it can be printed without supports and stil install the fan, this needs to be printed separately and then slided into place.
Just trying to work out, are you pushing air into the front of the GB10, allowing the cables out the open end of the enclosure, are are you pulling air out the back (in which case we’d be looking for somewhere to do some cable management and a hole to exit the cables). I have quite few gubbins at the back of mine right now, I do mostly run headless, but it is connected to 2x Displayports + Audio & USB hub for HID devices on my KVM switch.
Wow, so this version works for both the ASUS Ascent GX10 and the Gigabyte AI Top?
Yes the 3U version is pushing air in the front.
Yes
Nice and functional design, just a shame it is hiding the nice looking units in the process.
The Asus Ascent GX10 has the power button in the front :(
