An alarm is -triggered if the rotation speed has dropped below a programmable limit. Fan -readings can be divided by a programmable divider (1, 2, 4 or 8) to give -the readings more range or accuracy. Not all RPM values can accurately be -represented, so some rounding is done. With a divider of 1, the lowest -representable value is 480 RPM. - -This driver supports RPM based control, to use this a fan target -should be written to fan1_target and pwm1_enable should be set to 3. - -The 2103-2 and 2103-4 variants have a third temperature sensor, which can -be connected to two anti-parallel diodes. These values can be read -as temp3 and temp4. If only one diode is attached to this channel, temp4 -will show as "fault". The module parameter "apd=0" can be used to suppress -this 4th channel when anti-parallel diodes are not fitted. |
