for me low 30's is a normal summer day, hell, even in spring and autumn here in tropical Queensland that temp is common!
for example, last night the room temp was 27 and after the PC was on for a while, it reached 39 (southbridge).
I have a wall mounted, wooden, open to the air, custom built rig I did a four years ago.
I added two digital thermometers - one for the ambient temp and one on the SouthBridge as it's not actively cooled by anything and gets rather hot.

whatever cooling system you use, it should keep the processor within, say 20-30C of the ambient temp. any more than that and you are either over-working the system like playing games or you have an airflow problem.

have you changed the thermal paste on the processor?
try leaving the side cover off and blowing a fan into the chassis.
doing nothing and hitting 88 is concerning - have you opened it up and checked the CPU fan is indeed working? (y)
It is working well, but is too weak I'm afraid for the processor. I looked into the BIOS version, I had the 1.00 version from 2021 and I read the different versions for the BIOS updates... The most recent version from this year says "support for AMD Ryzen 5800X3D"... So, maybe that's one problem. I'm updating right now.
 
you are confident you got the correct BIOS version for your make/model/version of motherboard?

and to make sure I'm up to date - the processor is new, and the power supply, but you are still waiting on the new motherboard?

Yes, I'm sure I use the right BIOS version. PSU is new, Ryzen 7 5800X is new, the MB I am currently working on is the Tomahawk 570S, also new... I'm waiting a warranty for the Aorus X570 Pro Wifi, in the mean time I'm really out of ideas... Maybe the RAM or my 6 years old video card, that's the only component I can't change easily.
 
where did the Tomahawk mobo come from, new or used?
try taking the BIOS back to the previous firmware version.
on the Tomahawk mobo, have you tried only using one stick of RAM, and only having the SSD with the OS on it connect?

The Tomahawk is new, from Amazon, easy refunds. I've already tried the RAM slot process, eveb withouth SSD. But I dont know, maybe I missed something, the only constant here is the graphics card, that's my last move. Let me do the RAM thing en BIOS reset... But I dont know if I wan to have that Ryzen 7 on the stock BIOS version.
 
yeah, that's a drawback to having a processor that doesn't have onboard graphics, makes times like these difficult.

did you ever end up taking it all apart and reassembling on a piece of cardboard an on bench somewhere?

Yep. I did that multiple times with both mobos, Aorus and MSI. A lot of my testing was on top of the mobo boxes, most crtitical errors where on BIOS alone. Things got a lot better since I bought the PSU, but those **** reboots and shut downs are weird.

I'm working with one RAM stick and slowly reconnecting every HDD and SSD... Everything fine, for now.
 
so with the current configuration, one RAM, new PSU, Tomahawk mobo, etc, the system has not restarted itself?
Normal for now. Photos not loading... At least with the CPU, is At 86C and 90W while Halo Infinite is on the menu alone, havent done any playing yet, too hot to play? I'm scared to play honestly, lol
 
is that 86 temp with the PC still spread out on a bench somewhere?
and it's got a fan connected?
if all yes, that's on the high side.
where are you located? - what is today's temp?
is it hot and dry or hot and humid?

86 inside the case and the shitty Wraith Stealth cooler that comes with the Ryzen 5 5600X. Right now is not that hot, raining season, 16C.
 
ok, so we are setup back in the case.
good to know.
OMFG. New update... I was testing the PC, playing a little bit too. Two days, no thing happenned. But when I'm finished I'm always turning the PSU off, I didn't do it today.

Now the thing starts up by itself, no image on monitor, all fans at full speed, CPU error led on, and then it shuts down... And it tríes to boot again by itself... What is that behavior?
 
could be faulty PSU, faulty motherboard, even something stupid like the power button is pushed in and hasn't popped back out!

maybe it's time to start thinking (seriously) about taking the rig to a professional repair shop - once the new mobo arrives - and before you install the new mobo.

that way they can see the current behaviour, and have on hand your new mobo to replace.
