Question When Will BIOS Kick-in Heat Kill Switch?

[accesscpu_]

I have a AMD Ryzen 9 5900X in my system, with plenty of air-flow and four case fans. This thing runs out, which I've accepted. When rendering videos, I've hit as high as 90C. But according to this article on PC Gamer, AMD is fine with that and considers "typical and by design" according to them (their words not mine).

My question is this...

I checked my bios and the thermal throttle is set to auto, but I always assume that at 90C, the desktop would kick off. That's what used to happen on my old computers back in the day.

Is 90C no longer the danger threshold for cut the system off, and is it just throttling down now as the new heat-management method? And at what point will it just shut down, if not at 90C?

Update your post to include full system hardware specs and OS information,

PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

Tjmax is 90c but that's only heat throttling threshold. it would shut down at about 110c.
Which kind of cooling do you have, a half decent CPU cooler should be able to keep up to 80c, In mean time you could use Curve Optimizer to keep voltages lover, typically -10 to -30. all core.

All four air cool fans (be Quite brand). I only hit 90C for a few seconds, and average mid-80s at max load. So until the time comes I wanna go with a water cooler, I guess this is as good as she gets. Thanks for the info all!

What is your CPU cooler ? I suppose it's an 3rd party air cooler, much depends on it, case fans just help a bit, with an open case side they do almost nothing. That is best way to check how much case airflow is efficient.
Are those "all four" case fans ? If connected to a header that is not CPU_FAN , they should react on MB temperatures (VRM and/or Chipset temperature sensors) .

On short, it will not shut down so easily, there is a thing called thermal throttling which reduces cpu frequency to lower temperature to stay under 90 degrees, if cpu reaches minimum frequency and still goes over the temperature set in bios ( 90 degress by default) then it will shut down how it was said at 110 degrees.
