I just received one in the mail courtesy of
cooltechnica.com and my first impression is "wtf?" The barbs are polypropalene (very good), the top is lexan (not good, but eh ... ), and the bottom is about 3/8" of copper. The channels inside look to be maybe 3/16" deep and pretty wide. From my initial look at the block, it appears that only around 25% of the coolant flow will pass over the die area with the rest flowing around ... and if this is the case, the thin base won't allow the heat to transfer laterally very well. I am a bit apprehensive, but I'm going to swap it in place of my Maze3 tonight and compare the results for you guys. While I can see how the WW works so well, this looks like a flawed imitation of a similar concept, and I'm a bit leery of the design.
Enough rambling ... I'll hopefully have results for you tonight, if I can manage to swap blocks without too many problems.
If it works good, I'll be swapping the Maze3 onto my center PC on the rack and getting rid of the Black edge on it ....
