There are several heat related reports in this forum (e.g. DGX Spark. low fan speed, high temps, device very hot and DGX Spark Bundle Cooling Makeshift Rack - #4 by maiia ). What are your latest experience? Some have successfully trained nanochat on the Spark (straight run for 9+ days) and have not …

I was running a TensorRT-LLM optimization on gpt-oss-20b, and it got hot: From my own script (AI wrote, but I directed it). [Screenshot from 2025-11-13 17-03-02]

I wish that DGX Spark Bundle Cooling Makeshift Rack - #4 by maiia exists. I will totally buy one if it’s <$50. But for time being, I got my Arduino Uno Q to go with DGX Spark. I am thinking of building something like this: Total waste of a new state-of-art device, a perfect way to show off ;-) …

That actually exists? :o Wow, I feel so .. But now that you tested, yea, it would be bad get that condensation formed inside of DGX. Thanks for update.

If you’re asking about the TEC from the previous thread that’s the FS12-45 Tablet cooler and is ~$29 The QUICARD I’m replacing the TARGUS with is $69.99 The Acrylic Stand and TEC is $39.99 The actual “rack” idea with proper fans and TECs was over $4K and was not worth the build for minimal impact…

With the laptop fan base with built in TECs, propped up on the open acrylic stands and ensuring the vents are not obstructed with the mini TECs below, the units have been cold on standby, and cool running AI Workbench. I haven’t run anything heavy or overnight yet. So far this setup looks promising,…

Dang! That looks like about to take off to explore the Galaxy… or take over the world at least. Well, at least with that 4i4, it will be DJing killer death-rock music while destroying humans. A tip for future human-survivors: When the AI singularity do happen, in order to fight the AI Lord, just…

@haidij Yes I will, but the script is super dangerous as you can imagine, so I need to make it usable by others and put all the warning bells. Also it doesn’t and can’t include the manual part which you need to reimage the DGX Spark to create a smaller partition. Although, I found that I can use U…

@maiia Is that setup not causing any condensation on DGX Spark at all? Any chance of that would be deadly to DGX Spark being all aluminum exterior. I am planning to have a Arduino Uno Q with temperature and humidity sensor and shut DGX down if any of value goes critical.

That makeshift rack was 4-figures and wont do much.

This is what I currently have but I’m replacing my TARGUS Laptop fan with the QUICARD

Please be VERY MINDFUL with the TECs they DO make ICE, that’s why I have them below the vents and not touching the Sparks.
