    I would have never guessed that the fan would be in the middle.

  • Leith Bade

    Makes sense having the fan in the middle so both chips get equal cooling.

    Very reasonable mate. +2 xD

    Actually the fins of blower type HSF as this one, are formed in such a way, that they push air in one direction.

    The gpu core that finds itself closer to the bracket area will be getting a steady stream of air.

    Now I am pretty sure that air will not be pushed in both directions, so the second gpu, should be cooled bu the suction effect caused by the fan. Will this be enough to cool it sufficiently though? ❓

    You can’t make a simetric fan design like that to be unidirectional, it is a radial fan, sucks air from above, and pump it radially.

  • Psolord


    So what you are saying is that it will be blowing air in both directions? ❓

    Your description of the turbine operation is completely wrong. Read more about the centrifuge effect.

    Felix, I stand corrected. Thanks.
