FINTEK(4)                BSD Kernel Interfaces Manual                FINTEK(4)

NAME
     fintek -- Fintek F75375 temperature sensor

SYNOPSIS
     fintek* at iic? flags 0x0000

DESCRIPTION
     The fintek driver provides support for the Fintek F75375 temperature sen-
     sor and fan controller.  The sensor possesses a collection of sensor val-
     ues 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.
