It just never ends… -.-
Got it to connect locally, and threw together a bash script to manually set fan speed.
#!/bin/bash
echo "Fan control started"
for i in `seq 1 11`;
do
temp=`sensors | grep "CPU Temp" | sed 's/.*:\s*+\(.*\) .*(.*/\1/'`
temp=${temp::-4}
echo "CPU Temp: $temp"
temp_min=40
temp_max=95
fan_min=10
fan_max=64
fan_speed=$((($temp-$temp_min)*($fan_max-$fan_min)/($temp_max-$temp_min)+$fan_min))
if [ $fan_speed -lt $fan_min ]; then
fan_speed=$fan_min
elif [ $fan_speed -gt $fan_max ]; then
fan_speed=$fan_max
fi
cmd="0x30 0x30 0x02 0xff 0x$fan_speed"
echo "Command: $cmd"
# Enable manual control
ipmitool raw 0x30 0x30 0x01 0x00
# Set fan speed
ipmitool raw $cmd
if [ $i -le 10 ]; then
sleep 5
fi
done
This can be started with a cronjob to run every minute, and it will then check the temperature every 5th second and calculate the fan speed.
Fan speed is calculated from minimum and maximum temperature, where there is an lower and upper limit to how fast they can be set. (fan range is 0-64)
Well look at that! Gotta love some hacking! 
Congrats on getting everything sorted, albeit a lil side-door style! Makes it more interesting thought, right? Plus you can tell Murphy to fly a kite. 
I got annoyed of the fans changing speed at the smallest temperature change, so I added some averaging, so as long as the speed change difference is less than 15, averaging will be used. If the change is bigger than 15, it will just jump directly to it.
The values I have put in seems to be pretty decent, going from idle to full load makes the temperature start rising slowly, and the fans slowly spin up. But after 30-40 seconds the temperature really starts going up, and then the fans jump up to a higher setting, and averaging again takes over and keeps them steady there.
Doing the averaging and such would have been so much easier in python, but I wanted it done in bash to get it as “raw” as possible.

temp_max=95

# Average only when difference is less than
