I have looked everywhere, even sent an email to their support at Bitspower, but can't find details anywhere on their site about what materials this radiator uses. It lists in the specs there a "single copper fin", but says nothing about what material the other fins, ports, etc. are made of. If they were brass/copper, I would think it would be listed as such like on other brands/models. This gives me red flags for concern since I would assume it's aluminum based and very cheap. I certainly don't want to mix that with my copper/nickel I have for the other parts as that will cause trouble. Any thoughts or details on this or the radiator?
