Hi, first time posting here so I hope I’m doing this right haha. So I just got my ryzen 385 motherboard today, I was so exited until I started using it and hwinfo showed me…… a 100°C on the cpu and gpu ??? The fan is installed correctly and spinning probably at 100%, the cooler seems…. corectly seated, what’s going on, did I do something wrong?

34 to 100°C in less than 5 minutes, with a package power of less than 70W, that does not look right to me, especially with the CPU fan running - I would contact support with all the information you already gathered.
As the board comes with the heatsink and high quality PTM preinstalled I would not recommend to do anything like repasting and reseating the heatsink yourself as long as you have warranty, let FW handle that.

That looks unusual. 100 C is very hot. Phoronix did a 17 hour benchmark while monitoring thermals [1]. In that test the Q3 temperature was 80 C, the upper bound was 90 C, and a few outliers approached 100 C. If you were just stress testing AVX-512 on CPU and it reached 100 C it’s possible nothing is wrong or maybe there isn’t quite enough thermal paste. If that’s just the running temperate at 15% CPU from your screenshot something is definitely wrong.
My guess is the thermal paste between the CPU/APU and heatsink needs to be reapplied. Please be aware if you do take the heatsink off you will need thermal paste to reapply before putting the heatsink back on. It may be worth contacting customer support just to double check. Contact customer support.

The specs clearly state a PTM is used and not paste.
When applied properly this works impressively well, much better than consumer obtainable paste even when properly applied and I’ve seen enough people in videos doing it wrong.
My guess is there’s something wrong with the thermal interfacing.
That’s why I recommended to contact support to handle the replacement.

Thanks for the correction. I wasn’t aware a PTM was used.
With PTMs be aware that they have to be primed to give full performance. This might take a a few heat cycles (heating up and cooling down to room temperature) until the PTM works best.
But it does sound like something is wrong with your unit.
Alright, I’ll contact the support about it, I was hoping I could dodge it, anyway thanks yall.

Supid question: Did you put the fan in backwards? I almost did the labeled side goes DOWN, and make sure you connect the fan header!

Yeah, i even tried another fan thinking that maybe the noctua fan I got was faulty but it’s the same. I did a little experiment last night, on youtube the temps over between 70 / 90 degrees, I had the fan removed and was holding it in my hand while watching the temps. The weirdest part is that I feel like there is no difference between when I put the fan on the cooler or not. Even weirder, during games, when it skyrocket at 100°C, the heat sink feels…… warm at best? Like I owned multiple pcs and I feel like when something got to 90°C, it was HOT and also it smelled hot. I don’t know its really weird. Im just sad haha I was so exited to get my new pc 
And that confirms the heatsink doesn’t have proper contact because without a fan it should hit 90°C within a minute or two, I know because I did my first testings without a fan and measured temperatures with an infrared therometer.
I never have measured a heatsink getting that hot ever I think, the thermal interfacing normally is really good.
If the temperature skyrocketed to 100C the thermal paste is not applied correctly. If the temperature increased slowly to 100C it’s more likely the air circulation is insufficient. Repositioning the fan might work
Just keep the excitement a bit longer, Framework usually appears to be quite swift with replacements, just make sure to report all your findings for less back-and-forth with support.
