The comment about the block being better because of the "
greater water volume and thermal mass" says it all: this person knows little about what makes a good waterblock. You gotta love the "
They simply look better, and in my opinion, should simply work better". Where's the testing?
Looping the water round-and-round makes the block act as a secondary radiator, which is interesting: he ought to have taken advantage of that, by adding fins and a fan. Kinda like a water version of a Zalman block.
There is a reduction in the possibility of leaks, because he doesn't cut the tube at all: it remains perfectly integral. The problem is attaching a cold plate to it, in such a way that it doesn't reduce the thermal resistance, because lead/tin are relatively poor heat conductors. It's possible to flatten a piece of round tubing, just for making this block, but the bending work is pretty intricate.
Maybe this is the right block for Joe
