Your barbs are electroplated
. In essence, they are "protected", so to speak. That isn't to say that the nickel is completely sealed, because there will still be some corrosion; however, with something as small as the barbs in the loop (as opposed to the water block itself), the rate of corrosion is small.
Very true. However koolance already learned that already. when there products used nothing but engineering resign and gold. They only dissimilar metal in the loop in an all koolance system is the radiator. They have never really liked exposed copper due to the rate (even with water additives of every and any kind) that it oxidizes. Thats why every part of the blocks they now offer are plated. The only exposed metal in the loop is nickle (not including the radiator).
Does everyone think that the people who run these companies don't have forum trolls to watch peoples reactions to there products? Why do you think koolance stopped using aluminum in there new gpu blocks, and switched to acetel? Why do you think they switched to brass in there barbs and motherboard/cpu blocks? Why do you think they stopped plating with gold? Gold is cheap to plate with, cheaper than nickel. When everyone offers feedback instead of flaming things get done.
Nearly everyone that has somthing to say about koolance blocks compalins that they restrict flow. Correct me if im wrong, but doesn't having a large amount of surface area in a water block remove heat faster? And a large amount of surface area would result in less flow?
So, Less surface area(restriction)= More flow but worse temps
But, More surface area= less flow but better temps...
A perfect example follows in these two pics.
And personally they have a very new very sleek style
Look at the speed that DD and D-tek move during the development of a new water block. Compare it to the speed that koolance moves. Koolance moves considerable faster then both of them combined. And there products don't perform bad as a result. personally i have never seen another block hold a 4ghz q66 with delta t of 12c at 58c max on all 4 cores. Unfortuneatly since they stopped offering torque screws people really dont use enough pressure when mounting the block.
But don't take my word for it, take it from Xtremesystems. Which up until now has been the hardest on koolance for the use of aluminum. http://www.xtremesystems.com/modules...wcontent&id=56Edited by Blue_Fire - 6/1/08 at 11:37pm
