[Antimatter]

i think from what everyone is saying is: copper has better heat conductivity for volume. aluminum has better heat conductivity for weight.

this would explain why (small) waterbocks are made from copper and (large) air heat sinks are made from aluminum.

so aluminum would probably be a better material for a radiator if weight is an issue. otherwise, copper.

so anyway, i was thinking of maybe just running a bunch of copper tubing around in front of my fans. maybe i could solder some fins onto the tubes. would be very non-flow restrictive if i used 1/2" tubing.

im not sure if this will cool very well though. seems like it should get rid of some heat. it would be like 4 (7v) 80mm fans. some sort of spiral or something...
