# NAME

`fintek` — Fintek F75375 temperature sensor

# SYNOPSIS

`fintek* at iic? flags 0x0000`

# DESCRIPTION

The `fintek` driver provides support for the Fintek F75375 temperature sensor and fan controller. The sensor possesses a collection of sensor values which are made available through the sysctl(8) interface:

    $ 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

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.
