Rust on 420mm Nexxos Radiator

[d0nsherpa]

Hi,

I recently purchased a 420mm Nexxos radiator. The fins appear to have significant rust when viewed from both sides, as if they were not painted. Could this pose a problem or have any negative effects in the near future?

That is not rust, but the bare copper of the radiator fins and water channels. We apply very little coating to these areas because it would negatively impact cooling performance. All of our radiators look like this. Once installed, these surfaces are usually not visible anyway.

Thank you for the clarification.
