Well l've been bussy lately, preparing my new block, for testing, which I was gonna star yesterday, I set everything up, good enviroment for steady temps, water sensor, I measured the flow rate through all blocks, so I was ready to start testing. The board of choice was new Epox 8k5a for which I was sure that reads internal diode from Axp, but then it turns out that it only read it for thermal protection, and in mbm it only show temp. from socket thermistor, I just can't believe that. So now I have to wait to get 8k3a mobo. for test.
Ok, back to water blocks. and pics.
First take 16 2*4.5mm chanells, flat center 6mm base
Also see my mounting hardware, I made this brass bolts that lead the spring, and I screw those nuts just so that it doesn't touch the block top, this way I'll have constant mounting preasure on all tested blocks, preasure is great and the block doesn't move a bit, I also don't use shim anymore because of even mounting force.
Then I started making central cone block with 8 4*6mm chanells 4 & 6 mm base, this one has two layer top, because I wanted to design block with only one outlet, but it's basicaly one inlet four outlet, water flow on this block is just incredible best of all my current designs.
60° central cone with 10 mm base diameter
Based lapped with 1000 grit paper
And this are all the block I'm about to test next week, middle block upper row is comercial Magnum spiral block, then I have my two fin copper and Al spiral with 6mm base exactly the same design, middle block bottom row is the block I use until recently slightly modified top to have better flow, plus the block on first pic. which is already installed on my cpu. So lots of work for me in the following days.
