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.
