    I have had issues understanding what some TEC specs mean. I am trying to find out what the max temp is for the hot plate is before it becomes at risk of damage. i know my i7 920 has a max temp of 100C.
    Is this information present but difficult to decipher? or not generally specified?

    Type: TEC1-12726
    400W
    12V
    Couples: 127
    Imax [A]: 26
    Vmax [V]: 15.4
    QCmax [W] 177.8
    Tmax ˚C: 68
    Dimensions: 50 x 50 x 3.65mm [2 x 2 x 0.15"]
    Wire length: 101mm [4"]
    Fully sealed for protection against moisture

    why do you need to know this?

    well i want to make a TEC system and plan to add an extra sensor to keep the cpu temp above the dew point. I wanted to know the know the max recommended temp so i know how much coolant i need... If i understand it correctly it operates most efficiently if the hot side is <=68C?

    ahh okey:p i dont know what a TEC system is and i dont know what the numbers and that means.. was just curius why you needed to know :p

    a recent thought... please poke holes in the theory if you see one.

    copper "brick" of 2"x2"X6" ($65) (what are the dimensions of the i7 920?)
    using thermal compound and custom tension rods to affix the block to the CPU.
    Affix 5 X 45w (2"x2") TEC plate (one on each side and one on top).
    simple air coolant on each.
    may have to insulate exposed areas of the copper rod. the thought being to conserve the cooling affect of the TECs rather the allowing the copper to disappate heat.

    Improvements/flaws?

    The problem is this:

    Although copper is a very good conductor, it might not be able to move 300w+ of energy fast enough.... and your peltiers would probably get quite hot also, as the total amount of wattage would be crazy and the entire area around your heatsinks will bake. That will make them even less efficient and temps will go up and up.

    The whole point of petiers is to get the heat OUT and AWAY from the heat source. People 99.9% of the time use water and have radiators mounted outside the case to keep the heat away.

    If you wanna cool better here are the things from worst to best:
    Stock
    Air
    Water
    water/peltier
    phase/cascade
    liquid gasses

    Nothing else really is feasable.
