    Default Gigabyte GTX780: Fan running @100% at idle.

    Hello all,

    I've just built a new Xeon based development workstation (Params below).
    The machine has a single Gigabyte GTX N780OC GD3 card.
    My problem is simple, once X starts, the fan goes into full swing no matter what type of load is being generated.
    E.g. I'm getting the same noise level when displaying my normal KDE desktop (GPUCoreTemp at ~27c) and when running a Ungine benchmark (GPUCoreTemp at 55-57c).
    At all times, GPUCurrentFanSpeed is stuck at 17 (read-only... coolbits?) and GPUCurrentFanSpeedRPM is stuck at 0.

    Any ideas what I can do.
    I'll be shame if my wife will throw out my new brand new workstation out of the window :/

    Machine configuration:
    MB: Intel S2600C0.
    RAM: 32GB RAM.
    GPU: 1 x Gigabyte NGTX780OC 3GD.
    HD: 4 x 2TB in software RAID10.
    OS: Fedora 19, x86_64.
    DRV: v331.20 (RPMFusion).

    I should add that:
    1. The performance is right on the mark (~10% from Phoronix' Titan review).
    2. The GPUCurrentClockFreqs seem to be running between 954Mhz (idle) and 1110Mhz (Unigine Valley). I would imagine this is quite high for idle?
    3. On the other hand, power draw seems to be OK during idle (~200w) and at 100w more when running Unigine Valley (~300w).
    4. FWIW this is a copy of the this [1] thread.

    Thanks in advance,
    Gilboa

    Guess the first question that I have to ask is have you tried it in Windows and does it work properly there? The reason I ask is that if the fan rpm reads zero then it is possible you have a bad fan on the cooler that is not reading right (or plug/sensor/etc). If it works in windows then that eliminates bad hardware.

    I plan to do it.
    Though, my gut instinct tells me that its a driver -> video BIOS issue and not a defective card :/

    Did you upgrade the firmware? Usally Gigabyte has updates for gfx cards. I upgraded it on my GTX 650 Ti and one board can now boot without CSM. But my Asus P8Z68-V still needs legacy mode

    I'll search for updated firmware.
    Thinking about CSM, I'm currently using it. I wonder if switching the board to full UEFI will make a difference (doubt it).

    Kano,

    Thanks!

    I'll write the complete answer so people facing the same issue might stumble upon this solution.
    Here goes:
    In order to find which BIOS to flash, I first went looking for the current GPU BIOS version at:
    $ cat /proc/driver/nvidia/gpus/0/information | grep BIOS
    Video BIOS: ??.??.??.??
    In short, the nVidia driver, beyond not being able to detect the fan speed, was also unable to detect the BIOS version - in short, something is very wrong the machine's POST sequence.
    Went into the Intel MB settings (BIOS) and hiding under Advanced -> PCI Configuration was Legacy VGA Socket which was considered to initialize the wrong slot (1 instead of 2).
    Setting it to Slot 2 + complete power off + PSU disconnect (a simple reboot didn't help) and I've got a silent machine.

    Most likely this issue will prevent me from installing a second GPU, but to be honest, at least for now, I couldn't care less
