spray painting my radiator

Im thinking about spraypainting my radiator silver to go with my case. Would spray painting my radiator do any harm like cause a rise in temps or anything??

it doesn't effect performance at all for exterior painting, I mean for outside radiator excludes the tubes and fins

Edit: This is my PA120.2 Radiator

Painting your radiator won't do anything to temps, unless you somehow clog the fins with paint. Just don't excessively paint over the fins, just a light coat to get them a little bit of the color you want, and it'll look fine.

I third that.

I cover the fin area with a piece pf paper folded to size and put 2-3 coats of paint on the tanks and frame, then remove the paper for the last light coat. That way it all matches and the paint on the outsides is thick enough to withstand a little abuse.
