First thanks everybody
@Bill I need to find the way for that, but I will look into it, but it's not that huge anyway 0.5mm. As for too thin yep I know
@ Hara that chanell cut is only 1.5mm deep it was only ment for improving turbolence a little and flow distribution to outer channels. My method of measuring definetly can't pick that kind of details, heh even loading program fluctuate all the time so I can only tell about average on longer period, and in that longer period I can't hold my water temps constant
Channel height depends on a model from 3.5-5mm like I said still testing.
@ m3_arun see avatar and I made it in two dimensions too so again still some testing for me, lots of combination left to try
@ Puzzdre, currently with one MJ1000 other started making some noise, so I need to check the impler next time I take everything apart. Gain from before was more then 5°C or more then 50 MHz of stable oc.
@ ChrionN, damn you had to remind me of that, no project on hold, I found out that I can make lots of thing that I would have quite some problem making with cnc, because my tooling and work pieces handling isn't automatic, and because I don't realy make lots of block (1-2 a week) I rather enjoy making them by hand
but I will definetly finish that project.
@ Thanks man, you were inspiration to realy started me thinking on machining process, one of my older blocks had something I could barely call micro fins they were made with 2mm bit and I broke two of them before finish it, the results were good but not that much better to justify the cost of tooling, then I saw your block and how they manage to make those fine channels, so then I realy started thinking again how could something like this be made by me, and this is the result with matching performanse boost
