Hi there, I'm running Ubuntu 14.04 LTS on a fresly built server using ASRock C2750D4I. This is server/rack mini-ITX motherboard. I bought and install last week 3x Noctua NF-F12PWM (4 wires) in replacement of the factory fans of the case (SilverStone DS380). In the BIOS, I can select SmartFan for each of the fans or a level between 1 and 9. I forced the speed for now, waiting for a potential solution ;-) I noticed that lm-sensors was showing only 2 of 3 fans and both have zero RPM. IPMI on the other side is reporting the correct values but I cannot control the fans with it. Any ideas on what I can do to fix that? I'm more than happy to provide more logs/traces and I can even recompile some stuff if needed (kernel, lm-sensors). Thanks! D.

It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. Some south bridges, CPUs or memory controllers contain embedded sensors.

No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'... No Trying family `ITE'... No Some systems (mainly servers) implement IPMI, a set of common interfaces through which system health data may be retrieved, amongst other things. We first try to get the information from SMBIOS. If we don't find it there, we have to read from arbitrary I/O ports to probe for such interfaces. This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): Probing for `IPMI BMC KCS' at 0xca0... Success! (confidence 4, driver `to-be-written') Probing for `IPMI BMC SMIC' at 0xca8... No Some hardware monitoring chips are accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): yes Probing for `National Semiconductor LM78' at 0x290...

No Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now? (YES/no): Found unknown SMBus adapter 8086:1f3c at 0000:00:1f.3. Sorry, no supported PCI bus adapters found. Module i2c-dev loaded successfully.
