Currently there are isolated reports that Ryzen 3000 CPUs are dying or crashing on people after going through some serious stress testing/intensive workload. I'd love to ask people with serious science/engineering background why the new 7nm AMD CPUs run at a such a high voltage (1.45V), also given the fact that e.g. the Sandy Bridge CPUs from eights ago, based a substantially less advanced node (32nm), run at ~1.2V. I'm an absolute no one in this field but from what I've heard, the higher the voltage the shorter the lifetime of a CPU is. So, what could this high voltage mean for the new CPUs lifetime?

I experienced a once or twice a day thermal shutdown. My cpu was running at 80°C. 24/7 at 4100-4200Mhz. I tried down clocking and it made no difference, even to base clock 3800Mhz. Finally I thought what I had I changed between the 2700X and the 3900X. Answer: I switched to the 256-bit AVX application because it was faster by 3 minutes than the SSE41 app which I had always used for 1800X or 2700X. The AVX was handicapped on the earlier Ryzens and the SSE41 app always beat it in performance. So I reverted to the SSE41 app and immediately dropped 15° C. I would like to run the AVX app but I cannot with my current cooling solution which is a 360mm rad and custom block. So SSE41 app it is. System has stayed crunching for over a day now with no issues.
