Hi all,
   I'm attempting to install lm_sensors in to CentOs 5.3 x86_64 on a  
Super Micro

http://www.supermicro.com/products/motherboard/Xeon1333/5400/X7DWN+.cfm

I've tried both the latest source 3.1, as well as the rpm from yum  
which is v 2.10.7 with libsensors v 2.10.7.  I'd prefer to use the RPM  
version that comes from yum if possible.  Whenever I run the sensors  
command, I always receive the following output.

w83627hf-isa-0290
Adapter: ISA adapter
VCore 1:   +3.36 V  (min =  +0.00 V, max =  +4.08 V)

+3.3V:     +3.30 V  (min =  +2.82 V, max =  +3.79 V)

As you can see none of my fans are working.  I've read the wiki on fan  
control and divisors, but I don't seem to have any config options.   
Here is the config I have in etc/sensors.conf for my board.  I know  
that my fans must report data, as windows detects the rpms and I have  
4 pins on my fan connectors.  I'm also able to detect my temperature  
and fan speed in BIOS.  I'm sure it's a simple config I've missed, but  
I'm new to lm-sensors so any help would be appreciated.

Thanks,
Todd

# Same as above for w83781d except that in5 and in6 are computed  
differently.
# Rather than an internal inverting op amp, the 82d/83s use standard  
positive
# inputs and the negative voltages are level shifted by a 3.6V  
reference.
# The math is convoluted, so we hope that your motherboard
# uses the recommended resistor values.
