Thanks for the explanation, I think my earlier high rpms were because it was breaching the upper critical/non-recoverable threshold, so it all went to max speed. After a few power-cycles I have raised these thresholds and now the fans do seem to be controlled by the plugin OK. I currently have the min speed set to 12 and the CPU fans are now running at 600-700rpm and CPU is at 29-30C idle. It is so much quieter now too. Thanks again, I will play around with it some more once I start using my array.

You could try raising the low temperature threshold to 25 or 30. Thus pushing the scale higher. You also need to set the fan speed minimum to a value the makes the lowest fan speed greater than the speed set for that fan's threshold in the sensor config editor. Basically if your fan spins too slow or stops the bmc will kick it up to full speed. Thanks @dmacias, I guess I'm just not quite understanding what these values actually do. Is there a description somewhere about what each value actually means? Are the upper/lower thresholds the values that this plugin tries to keep the temps between? So it will react by raising fan speeds if the temp reading reaches above the upper threshold? I will try adjusting the minimum value, as you said, and will report back.

Hi folks, I'm a complete unRAID newbie, just setting up my first server. I have the SuperMicro X10DRi-T motherboard and I have installed the beta version of this IPMI plugin. I have read through this whole thread, thanks to all who posted and @dmacias for doing such great work. I am using Noctua F12 and A14 fans in my case. I seem to have cured the fans revving up/down by lowering the fan alert thresholds, so that's much better already, however my fans are still running really fast. My CPU is at 26C, PCH at 35C, yet the FAN1 is running at 1700rpm and FANA at 1200rpm. Surely they don't need to be anywhere near that fast when the system is so cool at idle. I have enabled Fan Control in the IPMI plugin and chosen the CPU1 sensor for FAN1234, and PCH sensor for FANA, but I have left the other values at their defaults (thresholds: 20-80C, minimum speed: 1). Can anyone help slow these things down? Thanks, Charlie
