    Aye - NEC hasn't released any images of the new system yet.

    80% less energy than a high end air cooling system? right.. so that would be 80% less energy than a fan? I dont think so some how...

    They might be referring to server racks/hpc systems, which are often like wind tunnels :p

    Sign me up, if this lives up to its promises, I will be getting one, maybe even two.

    I am very interested in which type of micro-compressor they used, anyone know?

    Hmmm, what else boils at 50° Celsius? :D

    Will it be like some HSF's that cope well with most chips but struggle with high end hot ones?

    sounds like it will take a few years to filter through to the consumer market

    If it's cheaper than watercooling I'm in.

    If it's as good as they say it is they'll make a killing in data centres and similar environments.

    Not sure about the 'impressive' reduced power claims, they seem a bit desperate to me considering your average pump uses about 20W plus a few fans which draw next to nothing - even if they used 70% less power this would still only be a saving of less than 18W. Not exactly earth shattering savings when you consider a GTX 480 uses 300W :D. If the vapour needs to evaporate at 50 degrees Celsius for the circulation to kick in, that's already pretty warm so it would be interesting to see how close to ambient one of these could get compared to a high end custom watercooling system.

    Again, i think the efficiency angle is for server rooms where a 70% saving could save significant money.

    Two questions about phase change coolers.

    C5H12 Pentan (Boils at) 36°C (ignites at) 309°C
    C6H14 Hexan (Boils at) 69°C (ignites at) 240°C

    First: What fluid is used in the "VaporX" coolers?

    secondly, in a normal ATX-case the graphicscart is placed "Upside down".
    Wouldn't the gas phase be at the hot point (die), and the fluid phase at the cold cooler side?)

    NEC discover how fridges work.
    Good work. :)

    Bit cynical but how can't you be with such claims.
