My science teacher said the best colour to paint all the radiators in your house would be black, but people pick white obviously cos it looks better
BUT, I always thought black aborbs heat where as white reflects heat

But which colour would allow the most heat to be taken away by the air passing is anyones guess

i'd probably say plain alloy so the paint or whatever doesn't act like a heat jacket
I'd preper black though cos it would look better, and aren't the RS500 coolers black?

it's too hard
