    You can do an evap of 10 cm tall, it is not a matter of height, it is a matter of internal surface and design.

    As always sory for my bad English :P
    actually hipro5 has to be more sorry for his english!
    sslinencer you are right about the cascade Vs sstages...

    as for the evaps design i have many ideas the last couple of months...
    1) i don't think base thickness must be more than 5mm. i have the feeling that with large bases we try to remove heat from a point too far from the cpu core itself!
    2) mass mass mass... i think mass is important in a weird way.
    an evap with more mass has more heat buffer to deal with the load until the systems low side responses.
    for example -100*C idle, apply 200W --> instant drop to -89*C then system stabilizes at -93*C

    but when overclocking, if i start my 32m at the limit MHz for -93 i will get an error when the phase instantly drops to -89, so i have to bench in the Mhz where i am stable at -89*C! i need to chop that delta between instant drop temp and i think this is how mass helps high loads

    3) so we need mass, but not base thickness, so what we did is increased the diameter

    (ssilencer that was what hipro5 was talking about when saying 'increased 4cm to 5cm' )







    this new baby from our friend eleven will be tested next week on a cascade that we know how it has been performing with the same design/base thickness 40mm version! (hope we find something )

    if this is your first night in xtremesystems,
    you have to overclock.
