+# Howto: Setting the fan speed of the Dell R610/R710
+Inspired by [this Reddit post](https://www.reddit.com/r/homelab/comments/72qust/r510_noise/dnkofsv/) by /u/whitekidney
+
+
+1. Enable IPMI in iDrac
+2. Install ipmitool on linux, win or mac os
+3. Run the following command to issue IPMI commands `ipmitool -I lanplus -H <iDracip> -U root -P <rootpw> <command>`
+
+**Enable manual/static fan speed:**
+
+`raw 0x30 0x30 0x01 0x00`
+
+
+**Set fan speed:**
+
+(Use i.e http://www.hexadecimaldictionary.com/hexadecimal/0x14/ to calculate speed)
+
+*3000 RPM*: `raw 0x30 0x30 0x02 0xff 0x10`
+
+*2160 RPM*: `raw 0x30 0x30 0x02 0xff 0x0a`
+
+
+**Disable / Return to automatic fan control:**
+
+`raw 0x30 0x30 0x01 0x01`
+
+**Other: List all output from IPMI**
+
+`sdr elist all`
+
+**Example of a command:**
+`ipmitool -I lanplus -H 192.168.0.120 -U root -P calvin  raw 0x30 0x30 0x02 0xff 0x10`
+
+# 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. 
+
+Script [Reddit thread](https://www.reddit.com/r/homelab/comments/779cha/manual_fan_control_on_r610r710_including_script/)
+
+
+*****
+**Disclaimer:**
+
+I'm by no means good at bash scripting or regex, etc. but it seems to work fine for me. 
+
+TLDR; I take _NO_ responsibility if you mess up anything.
