    waterchiller -it´s a PHASE CHANGE unit ! use a refrigerant compressor , condenser , expansion valve ( cap tube or TEV) , and vaporizator( platte HX - heat exchanger) so this is a EXTREME cooling 100000000%% , that water is cooled by refrigerant unit ..make temperature exchange refrigerant / chilledwater!!! it´s NOT dependent of ambiental temperature like "normal" water.

     

    so my question here is: IF i use a LN2 pot, mount a waterblock on his BASE , and this water block is allready introduced in my waterloop ( don´t need anymore the radiator and fans :) , just 2 or more waterblock´s), and then i cooled the pot with LN2/ DICE , that will make heat exchange POT vs waterblock , it is entuziast leaque aswell?? =))) because i use water...like people said above !! BUT this water is NOT anymore dependent of ambiental temperature!! like should be in enthuziast leaque!!

     

    if i had a winter with -20-30 * and bench outside with my waterloop, use proper cooling liquid ( antifreeze) in this case is NORMAL for enthuziast leaque -because the water is cooled natural form nature and like i said above -cooling dependent of ambiental temperature!!

    with 8600GT i had issue at lower ambient ( -5*C -last winter) , so i think is the same problem depends from gpu to gpu, prehaps earlyer issue on mine:D

     

    actually i moded 3x 8800GT ( G92 chips 65nm) card all insulated for sub0 benching and i give a try under my rotary phase change cooling( -65* ) 2 of them has cold slow ...i have poor performance in specialy heavy load ( line nature 2k1 , 2k3 etc..), and the last ,work very well on gpu 1080mhz , but if i rise the mem( hynix FP1) clock even 5mhz from stock freq sistem freeze instantly ...so the mem controller inside the GPU has cold issue or at these temps(-60) , i modded the bios directly at 1050mhz( because on air cooling this card can do 1250mhz with 2,25v) on ram and updated the bios card but no luck :( the sistem frezze even in bios ...so i have no solution for this issue ..

     

    from 4X 9600GT only one like -55* without shutdown the gpu power ( specify for CB issue)with vrm onboard..and 2 of them has same CS issue like your!

     

    try to put a thermal pad or alu/cooper plated( 1mm-2mm -3mm tall) gpu die/ evap base...only way is to rise the gpu temp ...if you want necessarily to bench that card:D
