✨ NAME ✨

pchtemp — the Intel PCH temperature sensor, no cap 🌡️

✨ SYNOPSIS ✨

pchtemp* at pci?

that's it. that's the whole line. iconic behavior honestly 💅

✨ DESCRIPTION ✨

okay so the pchtemp driver is the one that gives you support for the temperature sensor inside the Intel X99, C610 series, 9 series, and 100 series platform controller hub (PCH). so if that's your chipset, this driver is your girl 🎀

these sensors are out here giving 0.5 degC resolution — like, half a degree, she's precise ✨

and where do you actually see those values? through the sysctl(8) interface, bestie. that's the whole hookup 🔥

✨ HISTORY ✨

the pchtemp driver first appeared in OpenBSD 5.9. she's been around a minute, lowkey a legend 👑

✨ AUTHORS ✨

the pchtemp driver was written by Mark Kettenis <kettenis@openbsd.org> — ty for your service 🫶✨

✨ CAVEATS ✨

⚠️ okay this is the important bit so listen up: the temperature sensor only attached if it has been enabled by the BIOS. if your BIOS said no, this driver said no. that's it. no sensor for you 😭 go check your BIOS settings fr fr
