my old holddown was reaaally bad, and i wanted a copper based block, so i got myself a new one with integrated holddown(to the 4 holes), as i seriously needed to do something about the temps my tbred-a was going to(load 50c+ in the insocket..)..
the old block is the one on left in this pic, the new one is on the right, it's copper bottom with alu-top(am i worried about it disappearing? no).
the block on the left(old) costs 24€($) without holddown.
the block on the right(new) costs 38€ and needs no seperate holddown.
the old and new block share the same top-attachment screw configuration(and afaik are internally identical), so maybe someday when i'm reaally bored i could do some testing, see whats the difference in temps.. also, if the holes disappear from motherboards i can switch the top from the all-aluminum block and use some new holddown.
the blocks got some sort fo maze in them that the company calls 'SingleFlow' (as opposed to DualFlow in their high end p4 block), haven't checked the form yet(i don't have the proper head for my screwdriver).
after some serious screwing the nuts.. by hand&with screwdriver to keep it still, and one additional 5v mod soldering..
and with everything back in case:
am i worried the hoses get loose? no i'm not. they're very tight fit, theres a short bit of smaller tubing over the nip that the larger tubing goes over. yes the tubes ain't very clean but thats what 2y+ of open bucket cooling gets you(and i don't care that much of it).
load temps at ~36c now. (water is 22c, and stays so, open ~24l bucket with ~15cm fan blowing on the water) happy camper.

including some pics of the blocks bottom.
the screws/nuts were plastic, i might look for metal screws sometime. the nuts came with springs though and the installation was a breeze.
