I have a FreeNAS server that runs a VM for Plex and usenet automation. It has a SUPERMICRO MBD-X10SLL-F-O motherboard https://www.newegg.com/supermicro-m...N82E16813182819

Earlier this year I installed two Noctua NF-R8 PWM fans since the last non-PWM fans started whining. Now the fans consistently spin up and slow down. I looked in the manual and saw that I can control the fans in IPMI https://www.supermicro.com/manuals/motherboard/C222/MNL-1428.pdf

I login to IPMI and there's a fan setting. It's set to Standard so I switched it to Full Speed and then the fans are always at full. If I set to Optimal or Standard it spins up and down.

The weird part is that for a long while they were at their regular speed for no reason. Lately it's spinning up and down more. A few times I could just reset the server and it would stop, but it would be back in the morning. Now nothing seems to work. It's driving me crazy since I sit right next to it! Please help!

update: I ordered some of these so we'll see if setting them to Full and lowering the RPMs will be ok https://smile.amazon.com/Noctua-NA-SRC7-Low-Noise-Adaptor-Cables/dp/B00KG3KP1U?sa-no-redirect=1
