Discoloration on GPU IO shield. Dangerous?

I just noticed these black spots around the HDMI port. It looks like black spray paint that smudges when touched. It’s a 5 month card and it has been performing well. After reading online it seems that the aluminum has started to have discoloration due to the heat. 

My card doesn’t run hot though. The highest recorded temp is 72C. And that’s a rare occasion.  


Is this a sign of anything dangerous?

 

NOTE: I am aware it looks like oil/dirt but I definitely haven’t been touching it with anything like that. Apparently the discoloration can cause some trapped residue to come to the surface. Seems to happen with aluminum.

It could be mold or surface rust. Either way, don't lose any sleep over that.

Why? Is that harmless?

Could it be some paint from the black cables rubbing off on the metal? 
 

Anyone ever encountered similar? Ideas?

 

UPDATE: apparently it’s mold?

What makes you think it's mold? To me it looks like dirt/dust. It also looks like it is in the crack between the IO plate and the case. 'd just wipe it off and move on.

There is a gap. I have made sure the the GPU is properly set in place. I guess the case is a little offset. It’s the h500 and it’s kinda bulky so idk.

There is nothing wrong with having a gap, What I am saying is that I see dust in and around the area that you circle. What makes you think that it is mold and not just more dust that is already there? Do you live in an overly humid area? Do you have mold other places in and around the PC? Walls? Floor?

I was reading up and it turns out that it’s aluminum discoloration due to heat. Seems to be the most logical case with other similar instances online. Though this card runs quite cool. It’s the 3060ti by MSI

There were some minor black spots of mildew on the IO shield of my 3060Ti. 
 

How serous is mold when it comes to PC parts?

Well, mold tends to grow where excess moisture is present, would recommend some high conc IPA and a dehumidifier.

If mild is growing, that means that significant moisture is condensing, or that a very moldy area is very nearby.

Funny thing is I have no mold anywhere else in my house.

I'd look harder, mold likes to hide really well. also check the seal on toilets

I question whether it is even mold in the first place. I don't think it is.

@Victor Jones do you have a picture of said "mold"

here i dont think its mold anymore. it is like a greasy substance that appears out of nowhere whenever i touch the IO shield with my CLEAN fingers. maybe its some reaction with the metal due to heat?

If it comes back after an IPA wipe down, not sure.
