You can see the simple bash script below for reference: #!/bin/bash This can happen if the iDRAC is reset in any way (FW update, SW reset, sustained power outage). I took this one step further and made a bash script that I can call at a moment's notice if the settings get reset. This method worked great for me and I have used this on all my servers in my home lab. You can find most of the critical temperatures exposed in the iDRAC web interface. However, it is worth double-checking your temperatures and running some synthetic loads to see what the worse case would look like.

In my case, this was not an issue since my server never goes near full load and my ambient temperatures are consistently quite low.
The downside to setting the fans to a static speed is, of course, reduced cooling performance and no reaction during high load. It's worth sweeping through the speeds on your setup and finding the highest speed with an acceptable sound level. I found that the lower speeds had a lower frequency sound which was actually more noticeable than the higher frequency whine at slightly higher speeds. In my case, with the R730 server, I found that the optimum fan speed for minimum perceived sound was 11% fan speed. It may be counterintuitive, but to minimize sound level, lower fan speed isn't always better. It will return to automatic mode upon an iDRAC reset.

NOTE: The static fan speed commands only work if the speed controller is set in manual mode as set above. ipmitool -I lanplus -H -U -P raw 0x30 0x30 0x02 0xFF įor example, setting the speed to 10% (0xA) would be as follows: ipmitool -I lanplus -H -U -P raw 0x30 0x30 0x02 0xFF 0xA To set a static fan speed run the following command with your own iDRAC IP, credentials, and fan speed as a percentage (0-100) in hexadecimal format (0x00-0圆4). To put the fan speed controller into manual or fixed speed mode, run the following command with your own iDRAC IP and credentials: ipmitool -I lanplus -H -U -P raw 0x30 0x30 0x01 0x00 Set Static Fan Speed This is what we will use to send raw IPMI commands to the server.

To do so, open a terminal and run the following command: sudo apt install ipmitool The first thing to do is install IPMI Tool. Make sure IPMI Over LAN option is enabled in iDRAC as shown below.Know your Dell iDRAC IP address and login credentials.Have access to a Linux machine (Ubuntu recommended).No resistors or soldering irons required this time, nice. Luckily, the newer generations of PowerEdge servers since then have a standard IPMI interface and some known commands to manually control the fan speed. When I first got into servers and HomeLab years ago, the standard and accepted way to quiet down PowerEdge servers was to add a resistor in series with each of the fans. Fear not! This quick tutorial will get your server to STFU in no time! Or worse yet, you just added an "unsupported" GPU or another PCIe device to your PowerEdge and now the fans are ripping at near 100% and screaming away like a jet engine. You just got your new shiny Dell PowerEdge server all set up, but you are getting annoyed by the constant fan ramping up and down or the louder than desired whining of fans.
