How to control fanspeed on a RN104

I Wrote my own simpler way

#!/bin/bash

string=$(sensors *-isa-* | grep T-junction | rev | cut -c 67- | rev | cut -c 16-)

timestamp() {
date +"%Y-%m-%d_%H-%M-%S"
}

( echo "temp was ${string} at $(timestamp)" ; ) >> ~/tempmon.txt

if [ $((${string})) -gt 65 ]; then
 echo "210" > /sys/class/hwmon/hwmon1/device/pwm1
else
 if [ $((${string})) -lt 50 ]; then
 echo "150" > /sys/class/hwmon/hwmon1/device/pwm1
 else
 echo "170" > /sys/class/hwmon/hwmon1/device/pwm1
 fi
fi

Then I just edited a system cron job to include running this every 30 minutes, 

/etc/cron.d/frontview-volumeschedule

and added

2,32 * * * * root script/location/name.sh 5 &> /dev/null

It also writes to a log file so you can see how it's performing.

the last few entries read

 tail tempmon.txt
temp was 56 at 2015-09-28_08-32-01
temp was 56 at 2015-09-28_09-02-01
temp was 55 at 2015-09-28_09-32-01
temp was 56 at 2015-09-28_10-02-02
temp was 55 at 2015-09-28_10-32-01
temp was 56 at 2015-09-28_11-02-01
temp was 56 at 2015-09-28_11-32-01
temp was 57 at 2015-09-28_12-02-02
temp was 57 at 2015-09-28_12-32-02
temp was 56 at 2015-09-28_13-02-02

So the sripts doing its Job and it doesn't need to run as a service as cron takes care of it.
