I was wondering how they can run that cpu without any cooling.. Then they say it goes up to 90°C .. That's way too hot! thats like laptop / mac temperatures. It will function sure, but it wont last, it will degrade relatively quickly.

How quickly is quickly? I've never had a CPU break on me, I still have laptops in storage a decade old that work fine, only they're too slow for the modern web. Perhaps 90C is reasonable for the time you will be using the device.

  Individual transistors will break, the cpu will continue to work, but it will run slower. That's probably why your old laptops are "too slow for the modern web". " Some circuits and buses are protected by error correcting codes (ECC). If a transistor becomes marginal—meaning that it works most of the time, but occasionally fails—and thus only causes occasional glitches in those buses, then the processor may continue to function. However, it will likely trigger ECC correction events and suffer performance degradation. These ECC events are a sign it’s time to replace the processor. If that transistor fails completely, the processor may still limp along, but it will not be running at full spec if it does. "

    The Linux kernel will complain loudly if ECC, etc kick in. It is more likely that the thermal paste will degrade, the heatsink will get dusty, or things will start requiring missing GPU APIs, and fall back to software rendering. Transistor efficiency also drops over time (creating more heat). Usually capacitors or connectors fail before that matters though.

This specific processor should support an eco mode, minimizing that problem. I'm not sure ofc the board enables the option. Also relevant for the ryzen 7000 processors, where that mode limits performance minimally but saves a lot of energy. Sadly not on by default, but seems to be a regular AM5 feature now. I personally would use a regular case with the noctua passive cooler, then add a case fan to only start on high temps. But my setup right now is so quiet it does not seem necessary (5675c cooled by an aio, fans and pumps throttled, noise isolated case - not audible for me on idle and very quiet on load thanks to a low fan curve, set by the excellent fan2go).
