3080 Can this be corrosion in my brand new (sealed) 3080 or just dust? Should i worry?

[Senbetsu]

Bought a brand new 3080 msi ventus oc, a friend of mine received it and mounted for me since i wasnt at home at the time. So far it has been running fine, maybe a bit hot on games like rdr2 or benchmarks (max temp 81º). 

 

A few days later i bumped with a video about gpu corrosion and thought tha the color looked similar to the 3080 picture my friend sent me.  And now im in doubt if its corrosion or what, its a sticked into the part of the heatsink showed in the picture (not at all in any place that my vision can reach), i can only take it off by scratching it with my nail.  What could this be? Should i be worried? 

 

if this helps, when i runned the heaven benchmark for 30 min it didnt surpass 81º and had no problem at all (so far)

 

You can see it going drom the msi logo on the left to the right in the down of the heatsink.

This should be dust.
corroded aluminium and copper both should have different colors

It doesnt extend to other parts, just on the surface you see, so i guess that a good cleaning with some toothbrush should be enough. Once i clean it and see if all is okay will report to give you the correct answer if it ends up being so. Thank you!

Small bit of Cheeto dust, a little brushing should do.

That is really what it looks like, i wish it only were that some operator was hungry. I can peel it off just by scratching it without much effort, like when you scratch a lottery ticket. Is that a good or bad sign?
