[lm-sensors] Fan Speed From Asus X99-A

[lm-sensors] Fan Speed From Asus X99-A

[Richard]

How do I have lm-sensors report the fan speed of the fans attached to my
Asus X99-A motherboard? (Right now I can only seed the fan speeds by
booting into BIOS.)

lm-sensors does a good job of temperatures:

$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +41.0 C  (high = +87.0 C, crit = +105.0 C)
Core 0:         +33.0 C  (high = +87.0 C, crit = +105.0 C)
Core 1:         +33.0 C  (high = +87.0 C, crit = +105.0 C)
Core 2:         +33.0 C  (high = +87.0 C, crit = +105.0 C)
...

but no fan speeds.

My /etc/conf.d/lm_sensors file looks like:

======# Generated by sensors-detect on Fri Jul  3 10:01:46 2015
# This file is sourced by /etc/init.d/lm_sensors and defines the modules to
# be loaded/unloaded.
#
# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or
SPI).

# Load modules at startup
LOADMODULES=yes

# Initialize sensors at startup
INITSENSORS=yes

HWMON_MODULES="coretemp nct6775"
=======

Both coretemp and nct6775 modules are loaded according to lsmod.

Any idea on how to receive fan speeds?
