Make sure you set the below variables in fan_control.sh IDRAC_IP="IP address of iDRAC" cd /mnt/tank/fan_controlĬhmod +x /mnt/tank/fan_control/fan_control.sh

You will need to create a dataset for the script to reside in, then you will have to download the script from my GitHub and make it executable, this assumes that you have a pool called tank and a dataset named fan_control.

The server lives in my garage, which in Western Australia can get into the low 40s deg C. I use this script on a Dell T320 running TrueNAS 12 and it works great. I suggest that you trend you HDD temps to validate your setting and that you setup alarms in TrueNAS so that you get warnings if the HDD temperatures get to high. Please ensure you review the temperature set points for your use case to ensure your hard drives are kept at your desired temperature, change the set points as needed. There is no warranty provided and you use this scrip at your own risk. With non-RAID, the temperature of the hard disk drives is not monitored, which causes the fan speed to be higher to ensure sufficient cooling resulting in higher noise level. RAID Setup with PERC H310: A system configured as non-RAID has a higher noise level than a system configured as RAID. Directly from page 30 PowerEdge T320 Technical Guide The tower servers T320, T420 & T620 inlet temperature sensor is after the HDDs so temperature will be higher than the ambient temperature.

If monitored temperature is below 35deg C set fan control to manual and set fan speed to predetermined value. The script will monitor temperature, if it’s above 35deg C enable iDRAC dynamic control and exit program. In this blog I’ll show you a simple script that you can use to control fan speeds on Dell generation 12 PowerEdge servers.

They do this because the iDRAC has no idea of the HDD temperature so to be safe ramp the fans up. This is as designed by Dell, which sucks. The iDARC monitors system health, checks and logs what is installed in the system and controls the servers cooling systems.Īs you may have discovered, when you cross flash a Dell H310 raid controller to IT mode and as soon as the iDRAC detects that a drive has been inserted the fans spin up and get loud even when the ambient temperature is low, say 20deg C.
