Hi,
I recently bought supermicro board X12SDV-8C-SPT8F to act as my opnsense firewall and also as plex server (transcoding wasn't priority).
Since I wanted something with lower power usage after receiving my board I started checking power usage which was quite high 85w in idle in proxmox for entire platform (5x 80mm fans on low rpm, 2 memory sticks and 2 nvme drives, power supply is be quiet! pure power 11 400w 80+ gold) however setting CPU governor in proxmox to power save mode allowed me to drop power usage to ~50w at idle (still quite high but better than it used to be).
Then I turned off entire thing so only IPMI was up and that's probably the biggest surprise as it drew 12.5-13w I thought it's quite high so I decided to update IPMI and bios as well to see if it helps with power usage, but unfortunately it didn't IPMI power usage and entire platform didn't change so I called a day and turned off server (IPMI was up and running).
On the next day I started organizing cables inside chassis and power supply was warm, which was a bit weird since it was off for the last 12h+ then I touched CPU heatsink and it was even warmer than PSU, I checked ASPEED chip on board which is responsible for IPMI and it was cooler than cpu heatsink and PSU (but not completely cold). I don't want to remove CPU heatsink, but I don't think there is anything related to IPMI underneath to make it this warm. I decided to investigate it more as I also have another supermicro motherboard X10DRH-C with ASPEED chip (its a bit older 2400 vs 2600 on the new board) so first I checked if PSU (Corsair 750w) or cpus are warm to touch and they are not, psu, cpu, and other components are cold, only ASPEED chip had similar temperature to the one on the new board, but also the big difference was power usage, for X10 it's only ~3.6w.
Is it normal that IPMI on this new board draw almost 4 times more than IPMI on the older board? Any idea why IPMI makes cpu heatsink warm (some current flowing nearby to the IPMI(?))? Is there any other way to decrease power usage for IPMI and at idle on this new board because I honestly expected lower power usage as I have old PC with intel 6500t and gtx1080 and it uses 45w at idle.
