![]() One thing that had to be sorted out straight away, on pain of constant nagging, was the noise. # chmod +x /scripts/dell_ipmi_fan_control.I recently inherited an IBM 3650 M3 for my home lab – 2 x Intel Xeon E5645, 128GB RAM, 4 x 1.2TB 10K SAS – which is going to make a nice base for a new nested ESXi lab. # echo "*/2 * * * * /bin/bash /scripts/dell_ipmi_fan_control.sh > /tmp/cron.log" > mycron You may have to adjust the time frame depending on your server usage. I wrote a small script, that will check the servers temperature periodically (crontab) and disables or enables the dynamic fan control based on a temperature threshold.

So basically a 11th, 12th and 13th generation PowerEdge. I tested them with my R210II, T620 and T330. These are already widely known, but I wanted to list them again. I read threads on this sub and other boards and found a lot of commands. I did some research on how to manually controlling the PowerEdge fans. There were some threads complaining about server noise in this sub the last days. r/HomeNetworking - Simpler networking advice. r/pfsense - for all things pfsense ('nix firewall) ![]() Might be able to find things useful for a lab. r/hardwareswap - Used hardware, swap hardware. r/buildapcsales - For sales on building a PC r/linux - All flavors of Linux discussion & news - not for the faint of heart! ![]() Try to be specific with your questions if possible. r/linux4noobs - Newbie friendly place to learn Linux!
