One common thing I see from newbie water block designers and makers is they are not concentrating on maximizing surface area and convection over the area where it needs to be. I will try to explain it the best I can which isn't perfect, but hopefully some more educated people will jump in here and make this a tutorial about the subject?
Well here is an example I just drew up:
This is an example of what I am about to get at. IMO you should concentrate on the area right about the CPU die. The red square in the pic is the CPU die. I like to go about 15% further on each side to allow for moderate heat spreading. If you make your base thin enough you should be able to keep that heat in the area you want it, which in the pic is the pins and dimples. I got 2 sets of surface area in the pic. One is the dimples which if I where to build this block I would have a middle piece modified that had holes directed at those dimples, maybe pipes instead like in Cathars design here:
http://forums.procooling.com/vbb/sho...threadid=6666. Then the second set of surface area is the pins. My theory here is the water will first utilize the dimples surface area and then the water expelled from those would run around the pins which is the second set. Should in theory be maximizing the surface area above the heat source and should result in efficient cooling.
The deisng in the pic was made to have a single big inlet over the middle and a single outlet. The channel winding around the block really isn't needed, but might add the extra capability of using a TEC/pelt if so desired in the future.
So if anyone want to expand on this please do. A design tutorial is badly needed around here as people seem not to interested in searching for designs to get ideas off to make their own designs. And we might be able to add the theory of the design which might be missed in whatever thread they might be looking at. Well it is late here so if this doesn't make since then sorry.
