ive been thinking about cooling my 9700 mem aswell. im assumeing they have the same basic layout as a 9800, here is a render of my card: http://server5.uploadit.org/files/kbn2k3-9700np2.jpg

the main problem is that it would be very dificult to have a one peice block for cooling 4 modules near each other but on oppisite sides. i also dont think any design with a single block for each side would be very good - that leaves four seperate blocks of some kind. the easesy, cheapest, but slightly ugly and messy way to cool all of them would be like so:

having a peice of copper pipe running along the card, with thin copper sheet soldered to it which is mounted some how onto the ram. note that on my card there are small SMD between each 2 bga ram chips that i didnt include in my design, i think it wouldnt be hard to do that afterwards, but it may be different on your card.
another way to do it which i have thought about would be having a block for each two ram chips, about 2cm tall, covering both rams and going over the edge of the card enough for a mouning using a bolt to hold the two together on each side of the card. they would be connected together using normal tubing or copper pipe (due to the 180 degree bend needed). in this design the blocks should give maximum flow rates and not be restrictive, as ram does not output much heat.

also my card has no holes around the mems - thats why i think holding two blocks together with a bolt and a spring between them would be best for mine.
if you want i can send you the model of my card so that you can play around with your own designs. ive used truespace3 which is a free 20mb download from Caligari's site.
