To control the FANs speed via network we need to enable IPMI over LAN from IDRAC. ⚠️ Be advised that changing the fan speed may result in overheating and damage to the components. I will simply post here what I have done in my situation.

Thanks to god/internet, I also found a post where a user has been able to control the fan speed with the ipmitool. Recently I had to replace Dell certified mechanical hard drives with uncertified SSD drives on a PowerEdge T620 server and was unpleasantly suprised to find that the fans were spinning noisly when inserted.Īfter quick research, I discovered that it was a known issue and that Dell wasn't able to offer any solution…
