Kudos to DangerDen on being up there with the top performing blocks,they certainly work well enough.
Having said that the M3 is an awful design now I look at it!, it's size is good for a TEC, but for a CPU core?...
I noticed after my first real good look that there are in affect two channels that run parallel to each other over the core area, then merge into the long one that runs around the edge/outside of the block, these two channel are in fact halving flow across the vital area!
, then when it merges it is restricting flow in an area where there's no need/use, at the furthest point from the core. What can I do to improve this that does'nt involve totaly demolishing the block?. something that can be done without milling...
Turn it into a high flow block?, move the inlet (use 5/8 in/outlets) to the far opposit side from the outlet and 'do away' with the 'vertical' parts of the maze, so in affect it is an 'open' block with three horizontal fins?. maybe lower the height as well?, halve it to improve flowrate/velocity through the block and dimple the BP with a drill (ala Swiftech) for turbulence and to thin the BP thickness down. How would I work out optimum area to leave?, does anyone know the BasePlate thickness?...
Lower the level of the two channels over the core?, use silicone sealant to lower the Lexan top over the channels to improve flow rate through them?. would this yield any difference do you think?...
The last idea I can't explain without a drawing, but it'd involve having the outlet on the opposit side, in the area to the left of the inlet, I'd open up another 'hole' symetrical to the one there already is, to make the flow symetrical, I'd put a sort of < where the outlet is now to help direct the flow, I'd need to remove a metal from below where the outlet stops as well...
Which of these ideas do you think would yeild the most?, I'm putting my money on the 'open' block, with either an uprated pump or lowered, preferably lowered...
