GPU Block Cleaning

[BrunoAFK]

Is this actually gunk inside the GPU block? I've already rinsed it with distilled water, but it won't come off. Is there a way to remove it? Or maybe there's nothing there, and it's just my imagination The GPU block was purchased a month ago, and I don't think I should open it to clean it since that would likely void the warranty.

Looks like some kind of a channel to me.

That definitely looks like dirt. But at the moment it’s still far from being a serious issue. If you really want to clean it, you could use the Core Loop Cleaner (article number 13016). But right now, I wouldn’t do anything yet.
