to tell y'all the truth..... I'M TOTALLY LOST!!!.... so stop hurting me and yourselves.
Question by mADmAN = comparing 2 barbs with 3 barbs waterblocks... which is better/preferred and why?
I'd rather you'd compare the water block resistivity-> water contacts rather than numbers of barbs... cause there's no definite answer if comparing barbs.. it's the w/block(design for heat transfer via surface area -> c/w) that determine the best blocks...some blocks design uses 2 OUTFLOW barbs cause (in simple PLAIN INGGERIS) to create a lower pressure point than the INFLOW... elementary fluid dynamics... water flow from high pressure to low pressure... so in theory the more the OUTFLOW barbs the merrier it is... right? hehehe there's more to it than that. read on

Right. Just that designs like the WhiteWater are much more efficient with two outflow barbs because water flows out from the microchannels in ONLY two directions, out of each side.

In some design, geniuses uses the INFLOW pressure not oni for jet impingement effect but simultaneously creating turbulance to further increase the surface contacts with thermal median.. turbulance will oso dampen the kinetics of flow which in turn lowering pressure of flow (a good example is the G4 block... the cups, channeling and such).. thus a single OUTFLOW barbs is adequate, without sacrificing the thermal transfer efficiency.
but.. imagine if the G4 uses a dual/triple/quadruple barbs OUTFLOW....
okay ladies, some food for thouhgt.. lemme know what you ladies think and why.. I think that's a healtier reply post rather than spam like post... (no offence).
Another good way of explaining. but.. imagine if the G4 uses a dual/triple/quadruple barbs OUTFLOW....

To answer your last question, i mentioned it in what i explained, more outlet barbs DO increase flow rates (and higher flow rates=lower thermal resistance C/W). but then again, flow rate gains are minimal because jet impingement by itself is still very restrictive, in fact much more restrictive than a single outlet. Adding outlets will make it easier for the water to exit the block, hence less restriction for the water coming in from the jet impingement, thus you will still gain a small amount of flow rates.
my earlier post spam like post ar?
I was just trying to explain what I knew hoping that it would at least make some sense. hehehAnyway, to add to madman's pics, heres pics of the Storm G4 revision 2 to explain what a hybrid 2 outlet design looks like.
This is the midplate. As you can see, it has two outlets.
This is the top/upper plate. You can see that the right hand side, the water exits to an outflow barb. But on the left hand side, the water is channelled back to the main outflow barb. This will slightly increase flow rates, although gains are small. You could make the left hand side outlet to exit to another barb, but since the performance gains are so small, I'd rather only have two barbs, so does most people who'd like clean looking setups.
