lm_sensors not detecting fan

Hello all,

I'm having trouble getting lm_sensors to detect my fan. All it seems to be detecting is my cpu, and I'm not sure why. Any ideas?

Output of "sudo lsmod":

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No

Trying family `ITE'...                                      No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): 
Using driver `i2c-i801' for device 0000:00:1f.3: Intel Lynx Point (PCH)
Module i2c-dev loaded successfully.

Now follows a summary of the probes I have just done.

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

Do you want to overwrite /etc/conf.d/lm_sensors? (YES/no): 
Unloading i2c-dev... OK
Unloading cpuid... OK

Laptop is an Alienware 14 purchased around December 2013. The bottom of the laptop states that it was deployed on October 13th, 2013.

If you need anymore information, let me know and I will supply as soon as possible.

Thanks for any help in advance!

Re: lm_sensors not detecting fan

You are using a DELL Laptop and therefore need a special package to enable fan and sensor control. Please refer to this thread

https://bbs.archlinux.org/viewtopic.php?id=211423

for further information.
