[SOLVED]lm_sensors doesn't show fan speed (or much else)

I'm going to start with a bit of code to illustrate the context

$ sudo sensors-detect
...
...
Now follows a summary of the probes I have just done.
Just press ENTER to continue: yes

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

$ sudo sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +63.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:         +63.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:         +62.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:         +62.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:         +55.0°C  (high = +84.0°C, crit = +100.0°C)

Now, I was under the impression that Fan speed should be being displayed, along with other things. Am I missing a kernel module of some kind? I feel like it is an incorrect setup of mine. I can't find anything on the wiki page https://wiki.archlinux.org/index.php/lm_sensors or in the forums, but I feel like I'm missing something.

I do not want to add a dangerous kernel parameter but can't figure out what my motherboard is (or how to add the asus_atk0110 driver to my kernel configuration) from the suggestion here http://www.lm-sensors.org/wiki/FAQ/Chap … rnel2.6.31

EDIT: turns out the motherboard is W35xSTQ_370ST by SEAGATE. I don't however know how to use this knowledge to figure out if I should be loading any other kernel modules or what sensors are available, e.t.c.

Thanks in advance.

Most likely your hardware doesn't provide more information. I've seen this mostly in laptops. This is from my Acer:

[xxx@arch ~]$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +56.0°C  (high = +80.0°C, crit = +90.0°C)
Core 2:       +54.0°C  (high = +80.0°C, crit = +90.0°C)

I thought they all needed to supply the information of the fan-speed. Guess I was mistaken. Thanks foppe.
