I just assembled my FreeNAS whitebox, and first thing I noticed was that fan speeds were way to high, so I went to the sensors section on the IPMI web interface and found some troubling results.
The CPU temperature is being read as anywhere from 14C to 16C, which is impossible because the ambient temperature is 19.8C.
Secondly, the VCPU is being registered as absent, which also appears to be erroneous.
Here's a sample of the raw output from ipmiutil.
Other than the obnoxious fan speeds and incorrect sensor reading the system otherwise appears to be working fine.
Here is the hardware as currently configured:
CPU: Intel Xeon E3-1230 V5 3.4GHz Quad-Core Processor
Motherboard: Supermicro MBD-X11SSL-F-O Micro ATX LGA1151 Motherboard
Memory: Crucial 16GB (1 x 16GB) DDR4-2133 Memory
Storage: Kingston SSDNow V300 Series 120GB 2.5" Solid State Drive
Case: Fractal Design Define R5 (Black) ATX Mid Tower Case
Power Supply: EVGA SuperNOVA P2 650W 80+ Platinum Certified Fully-Modular ATX Power Supply
The BIOS and IMPI firmware shipped with the latest versions available. I have already attempted a factory reset with no change in the results.
Edit #1: This appears to be something to do with Ubuntu Server, which I initially installed to do a bad blocks test on my drives. When sitting in GRUB the IPMI sensors work okay, but once the OS boots it goes back to the erroneous behaviour. I'm going to try a FreeNAS install tomorrow to see if this issue persists, if IPMI works there then the issue is solved because I intend to use FreeNAS in the end.
Still curious as to why this happens though.
