Differences between acpi thermal zone and lm-sensors on the cpu temperature

jp flag

I'd like to monitor the CPU temperature, but I found that both paths contain cpu temp info, x86_pkg_temp under /sys/class/thermal/thermal_zone2/temp and cores' temp under /sys/class/hwmon/hwmon1/temp*_input.

What is the difference between the x86_pkg_temp of ACPI thermal zone and the core temp monitored by lm-sensors? Which one is more accurate?

A typical PC has dozens of thermal sensors that measure different things.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
