BTW, and I'll circle back to my original topic, which got no responses, I've found what I think is a very clean logger that's extremely light on resources and will do some basic graphing of results for you.
A simple temperature monitoring tool for Windows that logs CPU, GPU, and motherboard temperatures to help diagnose system crashes and overheating issues. - Drahanov/easy-logger

I'm using the portable version, and folks are telling me that the installer gets flagged by Defender when you run it because this is an unsigned executable, which is not particularly surprising. I don't think I got nagged at all about anything between download and running of the portable version.
Those of you who think everything's got to be under 70 degrees (and I don't) will have a heart attack at what's a typical morning of temps, shown here:
temp_log_20260121_103914.csv
I'm currently allowing it to log again, but have only just started, for this morning:
temp_log_20260122_112106.csv
It's not that everything's running at high temps all the time, but it's not at all uncommon to have 70s, 80s, and 90s, for more than "a second or two" if I'm chugging away with something that's processor intensive. When I'm not, the temps tend to hover in the 30s and 40s.
It's set to log every 30 seconds, I think the interval was the same yesterday, but am not certain of that.
