stoping copper heatsink from oxidising
I live by the sea now, so metals oxidise a LOT quicker than inland, I don't know a figure but from experinace it's a lot worse than twice or three times as bad.
Which is bad news for my copper Zalman, after a few weeks it's already covered in a thin film. Anyone got any ideas what i can do about this? I know there's a gold-plated one, but that seems a bit overkill.

unless you can do it in the pressure cooker I might find that a bit difficult.
Zalman sell gold plated versions already, seemingly not for performance boost (they list exactly the same max specs as plain copper) so I guess longevity.
If I was to plate it somthing black would prob give the best results, or should that be silver? I forget. Whatever colour it's no good unless I can do it without specuial equipment. I did once copper-plate somthing in science class, but then that seems a bit pointless here

I'm not sure how well this will work actually, having never tried it. You know, the whole theory vs. practice thing... but yeah, in theory, aluminum foil should work.
I'd buy some of that CLR crap they always advertise on tv, dunk the heatsink in it to remove the corrosion that's already there, then try the aluminum. If it still corrodes, then ignore me If it doesn't, you win.

For cheap and better than plain copper, I suggest MG Chemicals Liquid Tin. It is used for coating home etched bare copper circuit boards, and it definitely helps against corrosion, albeit not as much as gold. You would want to get the metal very clean first though.
