wicked BE, your a star. how thick is is 1/2 inch again ?

well as i am no longer working i have loads of time to make load of mess and like to experiment and make stuff.

this is my list of blocks in order of performance.

all tested with a 1.7 p4 with room temps 20-21 most at 20.5. each time i would mount the block 3 - 4 times.

1. 2.5mm akasa base with 4mm fins 30C load.
2. 4mm thermaltake base with 3mm fins 31 load
3. maze 3 31.0 load
4. 3.5mm akasa base with 2.5mm dimples /tubes 31.5 load
5. akasa 3.5mm base with 4mm fins 31.5C
6. 1mm base with many copper tube inlet 35 load as the base is not flat.

i used sandra burn in test as it records temps into a file and have the actual results saved if anyone wants to see them.

i think the thermaltake with a very thing base will be the best out of this lot.
i have tested some of the blocks on amd but due to a leak thats now not working too well but i found simular results.
