I ask you because on the be quiet website it only says that it has the 7 heat pipes are in copper (I think it is the ones that support and connect the base to the aluminum structure), I am also interested in having the base and the pipes around the copper base, those that support the aluminum structure. Can anyone tell me if the base of this heatsink is also made of copper? (because otherwise I would take the noctua NH d15) on the site it says: "base and heat pipes in copper"
