Martin's custom "Thin Line" waterblock worklog

[NicePants42]

I have access to a gallon of the stuff =)

Yeah, right next to the Daiquiri mix.

Nice work, Martin!

Edit:

Underside:

It looks like this is all good, but I might be seeing it wrong - it seems like the threaded side of the barbs might be protruding down into the outlet (and inlet) grooves. I would imagine that this would be bad, but I'm sure you've got it under control.

As for potential performance, I hate to be a wet blanket, but I don't think this design is going to work quite like you're envisioning. I'm no expert, but it seems to me that with your 45 degree cutting angle to form the pins, you've provided a very low-resistance path from the inlet to both outlets, which may result in less-than-the-best heat transfer along the most direct path, as well as create some low flow areas in the further corners of the block. I think the diagonal line from inlet to outlets in the best way to go, but I might consider a different pin layout in order to put more obstruction along the most direct path from inlet to outlet.

Also, I understand where you're going with the thin slots, but it doesn't seem like slotted outlets would be much help in terms of directing flow out of the block. In the end the water has to get through the outlet barbs, so I can't see why the outlet slots would make this easier. It seems to me that a slight, concave, rounded curve to direct water toward the outlet barb would be best - you didn't try to form a slot in the outlet of your MCP655, did you?
