set R710 fans to either manual 15% or automatic based on ipmi temperature

# Script for checking the temperature reported by the ambient temperature sensor,
# and if deemed too high send the raw IPMI command to enable dynamic fan control.

# Requires:
# ipmitool – apt-get install ipmitool

# IPMI SETTINGS:
# Modify to suit your needs.

# TEMPERATURE
# Change this to the temperature in celcius you are comfortable with.
# If the temperature goes above the set degrees it will send raw IPMI command to enable dynamic fan control

# This variable sends a IPMI command to get the temperature, and outputs it as two digits.
# Do not edit unless you know what you do.
