I can tell you exactly how I noticed it because it was on my workstation this reproduced originally.
I have a Ryzen 9 5950X CPU and it has a crazy fan ramp. Anytime a process maxes out the CPU it will be audible to me when I'm working. Now, to put this in perspective. It doesn't happen when I'm gaming. I can play Diablo 4 and Cyberpunk 2077 without this noticable fan noise but when setup.exe loses it, the fan noise is how I notice it. It will max out one core and I'm going to assume "never" complete. The longest I waited was 78 CPU minutes before killing the process. This would happen now and then but it would not prevent Chrome from successfully updating. So, it was bizarre to begin with.
