Just some points I wondering:

1) Both in Linux and in BIOS/UEFI it only shows 2 fans running, while I have 3 fans for the CPU radiator. The 3 fans are all connected together into the CPU_FAN1 slot on the motherboard. A 3-into-1 fan cable into the 4pin CPU fan connection.

There is on the motherboard:
1 Power fan 3pin
1 CPU fan 4pin
1 CPU fan 3pin
1 Chassis fan 4pin
2 Chassis fan 3pin

While I guess the fourth pin is the control pin for the fans.

2) How can I get more human readable sensor names, in0-14. SYSTIN, AUXTIN0-4, FAN0-6
Would be great to know what kind of voltage the different in# values are, also which kind of fans the different fan# are.

I can see that the sensors get the names for each sensor parameter from the following location
/sys/devices/platform/nct6775.656/hwmon/hwmon1
Is there any way to change these to more human readable names?
/sys/devices/platform/nct6775.656/hwmon/hwmon1/temp1_label = SYSTIN = MB?
/sys/devices/platform/nct6775.656/hwmon/hwmon1/temp2_label = CPUIN = CPU
/sys/devices/platform/nct6775.656/hwmon/hwmon1/temp3_label = AUXTIN0  = ?

After running sensors-detect again, the file /etc/sysconfig/lm_sensors added the Nuvoton driver
HWMON_MODULES="coretemp nct6775"
Started the lm_sensors service and now I was able to get much more information from sensors. Though not as much as you did in that program.

Missing: 
CPU Clock (but perhaps can be retrieved elsewhere)
Memory Clock (but perhaps can be retrieved elsewhere)
Memory temperature

What is SYSTIN, AUXTIN adn PECI temperatures? Where can I find out what in# voltage is tied to, CPU, RAM, etc.?

Also in my case it only shows 2 fans, but I have 3 fans attached to the CPU cooling radiator.

I executed sensors-detect and it found the Nuvoton. Perhaps I need a newer Linux kernel. I am running openSUSE Leap 42.1 with kernel 4.1.27

Just press ENTER to continue:  
Driver `nct6775':

  * ISA bus, address 0x290

    Chip `Nuvoton NCT6791D Super IO Sensors' (confidence: 9)

Driver `coretemp':

  * Chip `Intel digital thermal sensor' (confidence: 9)

Do you want to generate /etc/sysconfig/lm_sensors? (YES/no): YES

Copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors

for initialization at boot time.

You should now start the lm_sensors service to load the required

kernel modules.

Unloading i2c-dev... OK

Unloading cpuid... OK

I did find some files on this sensor chip driver

linux-l3hz:/home/djviking # find / | grep nct6775
/usr/src/linux-4.1.27-27-obj/x86_64/default/include/config/sensors/nct6775.h
/lib/modules/4.1.12-1-default/kernel/drivers/hwmon/nct6775.ko
/lib/modules/4.1.27-27-default/kernel/drivers/hwmon/nct6775.ko

On my new ASRock motherboard all I get is the section "Adapter: ISA adapter"

In the BIOS/UEFI it was able to read the fan speed of 2 out of 3 CPU radiator fans.

Both my PCs have installed the linux package

Of course the ASRock Fatal1ty X99X Killer has a sensor chip.

It provides many more readings than your old Asus board can provide.

Linux does not (apparently) have the capability to read data from modern sensor chips used on current mother boards.

It looks like Linux is reading the ACPI information, and ISA information. It's not done that way anymore. Things have changed since 2008, when that Asus board was designed.

My ASRock X99 board, similar to yours and using the same Nuvoton sensor chip, provides this information to a good third party monitoring program. I could not fit all of it on one screen, sorry. The "mother board" temperature reading is a simplified concept that is basically useless now.
