    Clevo 8970Ms should have native fan control working, but I don't think the Dell cards do. There are 4 stock vBIOS' I believe: Clevo 8970M, Dell 8970M, Clevo M290X and Dell M290X (there may be more I do not know about). Raidriar will be able to tell you more though.

    vBIOS will not matter for fan control, it was whatever communication chip they decided to use with the video card. For some reason, the clevo EC chip communicates fine with the m17x, but not the dell or msi cards. Imperative to get the Clevo 8970M version any nothing else.

    IMPORTANT UPDATE
    I finally bought a power monitor to see how much electricity the M17x R2 was trying to use with 8970M crossfire. Even when UNDERVOLTED, the power meter was reading 235W with 920XM TURBO DISABLED.

    You really shouldn't try crossfiring these cards unless you have a 330W PSU with the 240W ID chip mod

    You disassemble a 240W PSU, remove the ID chip from it and solder it into a 330W PSU. There is a thread on here somewhere with a guide and pictures, i'll try and find it.
