    Well, surely they can't o/c it more than its 2-slot capability. So I wouldn't expect great clocks out of the box, although it might o/c better, of course.

    I am confused how raising the fan can cool the graphics card more?

    The heatsink dissipates the heat equally in all directions. Having a fan close will make the heat go away quicker leading to cooler cards. Having the fan further away will make the heat travel a few cm's and then get to the fan before it's cycled away - leading to slight increases in temps.

    Powercolor's innovation may be innovative but is it sensible?

    As best I can gather, it's less about heat leaving the heatsink, and more about the air blowing over the cooling fins. The air being moved by the fan will travel in a conical shape. So the further away the fan is from the fins, the larger surface area it should cover, and so the more effectively it will cool.

    At least, that's the theory.

    Technically, BullDogg - if there is a gap between the fan and the heatsink, the air should flow out of the card to the surrounding area, at which point, convection should take over because there is room for the air to flow freely.

    It's the same principle as using a shroud with a radiator (watercooling). There's an area of dead space next to the hub of the centre of the fan. Adding a shroud allows air to move, and therefore cool, where previously it couldn't.

    “maximize the efficiency of air convection by increasing the space between fan and heat ”. In theory, this will allow for lower temperatures and/or lower fan speeds, which also means less noise.
    Why make it adjustable then ? If its better up, the user is only going to leave it like it !...

    Seems a no brainer to me ?

    Well it adds flexibility for if there isn't room for three slots - in which case you might say well just get a two-slot cooler, but this allows you to add a second graphics card at a later date while offering near-to 3-slot cooling performance/noise until you do.
