# Howto: Setting the fan speed of the Dell R610/R710

# Safety BASH script
I made a BASH script to check the temperature, and if it's higher than XX (27 degrees C in my case) it sends a raw command to restore automatic fan control.
I'm running this on an Ubuntu VM on ESXi (on the R710 box), but it should be able to run as long as you have ipmitools. It could be you need to modify the logging, to make it work with whatever your system use.
I run the script via CRON every 5 minutes from my Ubuntu 17.04 VM running on ESXi.

# Howto: Setting the fan speed of the Dell R610/R710
1. Enable IPMI in iDrac
2. Install ipmitool on linux, win or mac os

**Disclaimer**
I'm by no means good at IPMI, BASH scripting or regex, etc. but it seems to work fine for me.
TLDR; I take _NO_ responsibility if you mess up anything.
