wow thats nice! any idea how it performs? i was thinking of making something similar as my slk800 heatsink is soo good, better then the commercail block i bought, but it would be even better with water, but i think i saw your thread first, thank you for the idea
btw were the fins on the heatsink soldered to the base? when my h/s arrives (im not cutting up my slk800!!) im half hoping they are, then i can use a soldering iron to remove them one by one without the mess so i would just have to cut the others down to size - then the other fins can be used in my silver gpu block to inc surface area, something i think it needs. if the h/s is just one part, it would probably perform better, not by much though. acctually ive thought about cutting out the center bit below the fins and inserting a square of silver, thats enough of my ideas though, ive got a thread that ill try to share them in, think youve already seen it

if you have any more spare of that plastic i may be interested in buying some, will have a look on ebay first though as shipping from US to UK would cost a bit, that matieal isnt sold in the UK though, so i might just use copper , something for me to think about in my thread anyway.
one thing ive also been thinking about is how to get a good flow through all of the fins, as the outer ones wont get much, maybe solder a fin cut in half across the other fins blocking the top half which would also give faster flow on the input side, or slower flow on the output side.
very interested in how these perform, will you be making any more?
