Planning to Spray Black on my hyper 212 hsf now. will it affect its performance? Think will right once the copper parts are covered. any old birds can advise?

It will, but not significant. As long as you have good airflow passing through the HSF, you should be fine.

obviously it will affect performance bro. They left it clean to allow the metal to have direct contact with passing air. If you coat it with a layer of paint, you're doing something similar to why there is global warming.
