After this point, the RPM rise to 100% almost instantly, and most likely the fans will not stop once the temperature drops to the "zero fan stop temperature"- the probability of a malfunction of the video card cooling system is almost 100%.
Poor quality thermal grease, too thick thermal pads, crooked installation of the cooler, etc.

Yeah, for modern cards which have power limit that's a legitimate use case. It basically consumes as much as allowed, the only downside is - frequencies are significantly lower than they would be in any real application (throttled by power limit) so if there is instability related to that furmark will not detect it.

Also issues related to bad cooler installation or thermal interface are easily noticeable by abnormally high hotspot temperature/high difference between average and hotspot on modern cards which show that. No need to torture card in such case - can lead to failure.

If you don't have an RTX5090, then any modern game (which they now like to make on Unreal 5) is already torture.
For example, FrostPunk 2.
The picture shows a bare icy desert and some snow.
But the card power consumption is enough to warm up the game world.

My GeForce GTX 275 ran at 85'C for about 30 minutes before I noticed temperature problem, fortunately no damage done.

To turn it on for the first time, simply click on the question mark next to the "bus interface" inscription at GPU-Z
.

Target temperature set in BIOS is too high.

I think that NVIDIA generation had a transfer function, like 2% rpm for every degree. Or even a table Temperature = rpm.

For RX video cards, the temperature under load will always be equal to the "target T", which is specified by a single number.
Even on a poorly assembled video card.
The RPM will just be far from the "Target RPM"
