FINTEK(4)

💖 NAME 💖

okay bestie, welcome to the fintek(4) page — the manual name is Kernel Interfaces Manual, and I'm folding that in right here at the top like a lil name tag 🫶. The short version is literally: fintek = Fintek F75375 temperature sensor. That's the main character energy of this page, periodt.

✨ SYNOPSIS ✨

the setup line is exactly this, no cap:

fintek* at iic? flags 0x0000

💖 DESCRIPTION 💖

The fintek driver provides support for the Fintek F75375 temperature sensor and fan controller 🔥. This sensor possesses a whole collection of sensor values, and they are made available through the sysctl(8) interface. Like, the data is literally giving:

$ sysctl hw.sensors.fintek0
hw.sensors.fintek0.temp0=31.00 degC
hw.sensors.fintek0.temp1=29.00 degC
hw.sensors.fintek0.fan0=0 RPM
hw.sensors.fintek0.fan1=0 RPM
hw.sensors.fintek0.volt0=1.72 V DC (VCC)
hw.sensors.fintek0.volt1=1.34 V DC
hw.sensors.fintek0.volt2=1.73 V DC
hw.sensors.fintek0.volt3=0.90 V DC

💀 okay important, bestie: on some machines the fans will not function properly with the chip in default mode. Setting flags to 0x0001 will make the fans run at full speed to prevent overheating. not me being dramatic — that's just the page, fr fr.
