Are you talking about junction temperature, package temp, or heatsink temp? The only CPU I own with a package temp that's cold enough to touch is inside my phone.

Meanwhile some of my data center machines are a decade old and run at 75C all day. I've never had a CPU fail before the machine became obsolete

linux sensors command, where ever that is.

That data can't really be trusted, because various sensors often have large offsets or are just bogus on specific hardware. E.g. lm-sensors reports both a sensor with 0 °C and one that's usually something like 90-100 °C on my desktop, while also misreporting the CPU temperature due to not taking the AMD offset into account (might be patched in recent versions).

In terms of Intel and/or enterprise hardware, the values are reliable. You can cross-check them via IPMI Sensors (provided by BMC itself) or Intel powertop (by crosschecking cpu throttle states). Intel also writes relevant support code (cpufreqd, thermals, etc.) themselves.

The biggest offender in my experience is OrangePi Zero, but I need a thermal probe to verify it.
