![]() ![]() Dell has modified/removed the ability to control the fans via IMPI. These commands no longer work on any iDrac update beyond 3.30.30.30. I’ve read that some people have created a script to watch the CPU Temp and when a temperature threshold is met, like 76C, the script increases the fan speed. You could damage your system if the system gets too hot. Manually taking control of your fans will prevent the system from increasing the fan speed in the event of rising CPU or system temperature. Unfortunately, I have only tested this on my Dell R330’s, check the comments for other confirmed systems by other people. It should work for most PowerEdge servers also. Lets go verify the static fan controls in the iDRAC Web UI or also you can run the SDR command via IPMI.This post will cover how to silence your Dell PowerEdge R330 server. Next command you can control the fan speeds with the proper hexadecimal value for the ending, as you see 0x2D =45% so you will need to figure out your speed you want the server to be statically at. This next step below, will enable the static fan control for the server with IPMI.
