bigben2k:

Its on a P4 3.2Ghz HT. The tape part is lapped contact area for CPU. Its raised to about 3mm thus to avoid block touching the caps. Its pure Al.

Room temp is 28C. I think the Al is not conducting heat fast enough. The thickness of the Al base is 2-3mm.

The temp of CPU is not constant (changes with load immediatly to 55C and reduces at once when load is removed to 38-40C) and I am currently blaming Al for that. While the water remains cold (almost near room temp i.e. 28-30C)

Jaydee:

I have been running this over for a month now. I have not seen sign of corrosion as of yet. The barbs are screwed in with nyrol spacer to seal it off.

This is a large block. The four 'big' holes are mounting holes for LGA775 (see pic 1).

Should I go ahead and replicate the same deisgn in Cu? Should I remove the outer most track and thus reduce the size of my next block?
