Hi
I finally reserved on day to test all my new blocks.
So the contesters are: two fin spiral Cu 6mm base, AL 6mm base, AL 2.5mm base and last my home made with one fin in the channel 3.5mm base. Here are all together
First three blocks were made on Cincinnati Arrow 1000 CNC mill 1h for AL version and 3h for Cu one. My was made this way:

So next to my test setup. As my AXP suddenly died (it will be replaced), I had to use old D600 cpu which is even more difficult to cool because of the small core. Cpu was OC to 1079 Mhz at 2,1V (166*6,5) max Q= 84W which is higher than AXP 2000+ at 1,75V (71W) , mobo Epox 8KHA+, ddr 256mb pc2700 Kingmax, water pump Eheim 1250, all tubes 1/2" ID. First I setup mobo for easy and quick retesting of WBs.
Plexi plate on the back of mobo against to much bending of it.
And here is the cpu with thermal sensor touching the core.
I also measure temp. of the water on outlet of the WB.
For heating up the cpu I used Toast, so here are the results in graph:
and here the numbers:
Temp on the outlet after 20min of Toast were 20°C except for the first block that I test (al-2.5mm base) where it was 19.6°C
Here is another pic. with Al block testing.
From results you can see that Cu blocks are better, but not by mile like some think. CNC machined block will go in small production here in Slovenia by my friend for more info email me.
Btw I'll retest when I get another AXP.
Uf, my longest post so far.
