All copper CPU cooler ideas?

[Okjoek]

I know copper is expensive, heavy and iirc harder to manufacture as a heatsink, but for both SFF ideas or to just flex are there any good ones out there?

Zalman makes some in small form factor iirc

Servers typically use them

Last full copper coolers I remember were made by Zalman but they weren't low profile. Most today are copper but nickel coated and use steel heat fins.

 

As Anonymous015 stated servers sometimes use them though most 1U/2U server coolers are either solid aluminum or more modern ones are copper heat pipes and steel fins with a copper or nickel coated base.
