Thumbs up 5days of block testing finished, My best WB is...

Now that was same work... I just finished testing my different waterblock designs, and now installed top block back inside my case again, along with my new northbridge waterblock. And now I'm running my new agoia 1600+ at 2GHz 2.1V rock stable, and look at my max oc. at 2.2V 15°C water and unstable

Now I need to get all the data and conclusions in presentable form, I'll post all the details later and for now just show you my current top block:

Ok ,here are result of my test.
First let me describe how I did the test. First the room was unheated one in the attics with temp of around 15°C, motherboard was Epox 8k3a, placed in the table with no fans anywhere to influence air temp. around socket. The pumps were Maxy- Jet 1000 and I've done two test. First with one pump then I added the second one in series. The hosing was 1/2" silicon ones total lenght 1m, the pumps were in 10l reservoar and from and then they were conected to copper heatercore 25*18*6cm with two Sunon high speed 120mm fans on top, then to the block and then back to reservoar. For thermal greese I used silicon goop that was very low viscosity, I choose this instead of as2 because I could aply it a lot more constant then as2, plus because of low viscosity and even when aplied very thin the redundant goop would squeeze out from contact between core and block. Next the clamping force, I made special nuts that hold the spring in position, and I turned those nuts the same so all the spring were aplying the same force, and that force was equal for all the blocks and was also biger then amd recomended clamping force.

Then the test, cpu frequency was 1950MHz. core volatge 2,1V the loading program was Toast which from all the programs give me highest and least fluctuating temps. Block was heat loaded for 1h until water temp reach equilibrium, then I run another 10 min where I took the measurment each second, so after 600 measures, the test was stopped and I calculate the average max temp. for one block. All this was done with a help of mbm great util and exporting results to excell. Then I re run the test with two pumps in series.
First here are the tested blocks.

Ok, here are the results, http://www2.arnes.si/~mlivak/Round%20up/Graf.GIF

And this are the actual flow rates of the tested blocks.

I'm sure I forgot something to mention, but that's your job to remind me

Ahrgh, damn , yes of course the most imporatant data is missing. Ambient temp. as water temp. which is the one the matters because I didn't test the radiator was 20°C or rather all the temps. from the block were normalized to 20°C water.
