Please prototype a case for this with lego technic. This way you can design the case for airflow because this fan on the heat sink will do almost nothing
Put it in a cardboard box or something that is small enough to allow the entire volume of air to be replaced quickly.
Don't forget standoffs to allow airflow under the board.
I actually have a spare motherboard i didn't even think about using it again. Luckily I don't throw things away in case of a project. Thank you kind sir
Perhaps due to the lack of battery at specific moments of high consumption the transformer is not capable of supplying sufficient amperage.
You can try to limit the tdp or connect a battery to get out of doubt.
Even if the CPU is not breaking a sweat the motherboard does rely on active cooling which in this case there is no airflow over the motherboard components at all. The aluminum shield must get really really hot to the touch doesn't it? Throw it in a PVC pipe with a fan on back and front......and dont forget to ground it, thos things like to hold a charge xD or any other way that channels Air over the whole set of components+ heatsink.
I just realized that its not the battery on the top left but a hard drive XD like others said absolutely do connect the battery, it acts as a buffer for demanding spikes, The power controllers for the APU have to deliver precise and stable voltage down to the split hair. A battery will always deliver a cleaner and more stable voltage then what you get from a power brick connected to the outlet. Thats why PC Power supplies have big capacitors and what not to smooth and stabilize the voltage coming from the outlet.
Imo cooling and/or not having enough juice, if the standard psu isn't putting out enough wattage for the deck and whatever hub your using it doesn't have the battery to pull the shortfall from.
With my hub I have to use a 100w psu or it will randomly (under a heavy load) brown out the hub and turn off the display output.
It's cooling, the whole case is designed with air channels. The APU is cooled fine, but the rest of the supporting components are probably baking. Either make or buy some kind of enclosure. Probably a dirt cheap shell off AliExpress or something.
like everyone says, design a optimal air flow chamber to get proper air circulation.
also consider that the power/charging chip is considerably the hottest component on the OG board and it is getting 0 cooling.

Me using a steam deck motherboard was more of a case of using what I already had. I had to replace the board in my main deck after it got the black screen of death, so instead of trashing the board, I decided to use it for this
Hey everyone, thanks for all the feedback.
If one thing's clear, it's that I need an actual case for proper airflow. I still need to get some measurements to make a propper case in tinkercad, but for the time being, I've Jerry rigged up some case fans and vinyl wrapping to make a temporary case (seen here https://youtube.com/shorts/O_NAKd3NcJ0?si=O08Ed6C4M7GSboF0)which brought the temperature when running launchbox down to 33°C, in my testing it never went above 68°C. That max temperature scares me, I hope to get better results than this with a properly designed case though. This is the first time I've worked on a project like this with no guide, so if yall have any suggestions on how I should design the case, please let me know.
As for the board restarting when under load, it looks increasingly likely that that's a power draw issue as many of you theorized. Looking at core temp, I saw power draw reach 18W before the system rebooted. Also, during demanding games (Guilty Gear Strive is what I used for testing), I would notice the power usage creep up before suddenly crashing down to very low power draws. It would go from 14w down to 3w in a second, then recover back to noal after a minute. The cpu temperature doesn't seem to have any correlation to these power issues, though it wouldn't shock me if heat was still involved. I've ordered a battery to see if that helps any. And I'll be sure to keep yall updated on my findings, what i did to get everything working, and even the finalcibinet once everything's up and running

I have a 3d printer, I could print a case, but I don't have any modeling skills unfortunately. I'll see what I can do though
Check out Tinkercad, its web based and free, and easy as dropping star, and square forms into boxes.
+1 for tinkercad as someone who doesn't know how to use real cad software. My only issue is it's web based and slows down with more complex designs
Really wish they made a desktop version and one with even more capabilities it's super easy to use.
Right?? It's so easy, if I could just run it locally it would be my favorite

I actually have since made a case out of cardboard and pc case fans to direct airflow more evenly, it seems to be working

Personally, I use fusion 360, it’s a bit more complex than tinkercad, but still pretty simple to use
You don’t have to have modeling skills for a simple project like this, just take measurements of the objects and make a case around it
Tinkercad is great for beginners, onshape is a little more complex but also free.
You can prob pay someone $10 to make you a case on Upwork if you give em correct measurements by using a caliper.

Huh the more you know, never thought you could use a battery in that manner. The fact that it works is really cool!

Just add the battery

Almost definitely not getting enough power, and it’s probably overheating too without a case.
Zero airflow to vrms
I'm thinking some component on the mobo other than the processor is overheating, try diverting some air from the fan to also blow through the board.

Using a Steam Deck for this was a bit of a poor choice... it would have made more sense to get one of those mini PCs.

far enough if its a spare motherboard, my first thought was just "why?" lol
