evaporator can't transfer heat fast enough ??

[makaka]

If the internals of the evap are not good which I suspect with that vapochill one it does not matter what your hx exit temps are because if there is not enough surface area to actually transfer the heat into the refrigerant and cause it to experience a phase change then it will stay as a liquid and evaporate in the suction line. On my cap in cap ebap I can have the ebap at -10c but the suction line at -50c

if this is the case then how the same evaporator can cool a QX6700 (@ high volt and freq about 250-280w [1.75v /4.2 ghz]) and keep the cpu under -15c under load . The 3770k a lot less TDP @ 1.35v ???

if it is evaporator fault anyway then what evaporator you suggest to buy .
