    Giving the fans some time to reach full speed...
    Found the following fan sensors:
       hwmon1/fan1_input     current speed: 0 ... skipping!
       hwmon1/fan2_input     current speed: 0 ... skipping!
    
    There are no working fan sensors, all readings are 0.
    Make sure you have a 3-wire fan connected.
    You may also need to increase the fan divisors.
    See doc/fan-divisors for more information.
    I'm wondering if this is a side-effect of setting all the fans to "smart" in the BIOS. I have 3 3-pin fans attached to the REAR-FAN1, REAR_FAN2, and FRNT_FAN1 headers (confirmed in the IPMI console).

    BTW, the Nuvoton SuperIO chip is actually mis-detected, as it's a nct5573, not a nct6776. However, a post from a Nuvoton engineer on the lm-sensors mailing list indicates strongly that both can be covered by the same driver.

    I think I got the Voltages right, but if Bill could get the HQ engineers to confirm the information in the attachment, that would be lovely.
    Next step is to get the fans to quiet down a fair bit.
    I think the main problem is that the fans are not controlled by the Nuvoton SuperIO chip but by the IPMI/BMC. There must me some IPMI command to control the fans, we just need to find it.

    Please check your current BMC firmware version. The latest BMC firmware is 0.14.0 ASRock Rack > E3C226D2I and it has added the formulated Smart Fan function.

    Sorry to confuse you Bill, but yakideo and I are mixing in the C2750D4I into this thread. I'll PM you.

    Hey guys,

    Any chance of similar configuration information to label and compute the in-* for the Q1900DC-ITX? lm-sensors output is:

    Code:
    nct6776-isa-0290
    Adapter: ISA adapter
    Vcore:          +0.68 V  (min =  +0.00 V, max =  +1.74 V)
    in1:            +1.85 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
    AVCC:           +3.34 V  (min =  +2.98 V, max =  +3.63 V)
    +3.3V:          +3.34 V  (min =  +2.98 V, max =  +3.63 V)
    in4:            +0.90 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
    in5:            +1.70 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
    in6:            +0.82 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
    3VSB:           +3.26 V  (min =  +2.98 V, max =  +3.63 V)
    Vbat:           +3.12 V  (min =  +2.70 V, max =  +3.63 V)
    fan1:          2125 RPM  (min =    0 RPM)
    fan2:             0 RPM  (min =    0 RPM)
    fan3:             0 RPM  (min =    0 RPM)
    SYSTIN:         +39.0C  (high =  +0.0C, hyst =  +0.0C)  ALARM  sensor = thermistor
    CPUTIN:         +35.5C  (high = +80.0C, hyst = +75.0C)  sensor = thermistor
    AUXTIN:         +39.5C  (high = +80.0C, hyst = +75.0C)  sensor = thermistor
    PCH_CHIP_TEMP:   +0.0C
    PCH_CPU_TEMP:    +0.0C
    PCH_MCH_TEMP:    +0.0C
    cpu0_vid:      +0.000 V
    intrusion0:    ALARM
    intrusion1:    ALARM
    beep_enable:   disabled
    I would like to be able to monitor DC-in, 12V, 5V.

    Cheers,
    Jason
