Can a gpu have corrosion?

My gtx 1080 had what looked like corrosion from my car battery. There was a little bit on the things labeled pc# that stick out of the back of the card. It came right off with some 91% alcohol. Should I be worried? I believe my card is functioning fine. It was kind of green. Ive been using it for about six months, no previous owner. Could this be a sign the card has a flaw in it? I take great care of my pc, blowing it out sometimes twice a month. Im also under warranty so if this is a sign the cards going to give out soon id rather know now.
 
Also the corrosion wasn't there the last time I took my card out to clean it. At least im pretty sure I would have noticed something like that. It just seems to me like corrosion appearing in 6 months of use would be a bad thing. I live in Louisiana so I don't know how much humidity affects this. And why wouldn't the corrosion have shorted out the card? I have a h60 aio liquid cooler but it has no leaks im sure of that.
 
Very odd. The only thing that comes to mind is a bad / leaky capacitor on the board. If your not having crashes or any weird corruption in the video I would keep an eye on it. If it's under warranty still try to send it back to the manufacturer or wherever you bought it for a replacement.
 
Is it possible that your computer is not leaking onto gpu because checked google to see what this corrosion is and it says this on website

How Corrosion Occurs
Corrosion is an electrochemical reaction that appears in several forms, such as chemical corrosion and atmospheric corrosion, the latter of which is the most common form. When acidic substances (including water) come in contact with metals, such as iron and/or steel, rust begins to form. Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion). When steel is exposed to water, the iron particles are lost to the water’s acidic electrolytes. The iron particles then become oxidized, which results in the formation of Fe⁺⁺. When Fe⁺⁺ is formed, two electrons are released and flow through the steel to another area of the steel known as the cathodic area.

Oxygen causes these electrons to rise up and form hydroxyl ions (OH). The hydroxyl ions react with the FE⁺⁺ to form hydrous iron oxide (FeOH), better known as rust. Where the affected iron particles were, has now become a corrosion pit, and where they are now, is called the corrosion product (rust).

Corrosion can happen at any rate, depending on the environment that the metal is in. However, since atmospheric corrosion is so widespread, it is recommended to take effective precautionary measures when it comes to corrosion prevention.
 
I am just wondering how to prevent this from getting worst have you got an Waterblock Backplate protector onto the 1080 that will cover all the chips and such if not you could buy one because it might work to prevent this from coming back!
 
No I don't have a backplate protector. The aio is for the cpu and it doesn't run over the part of the card the corrosion was on. If my card is still working do you think I should try to rma it? They will most like try the card out and say it works fine no luck.
 


This is upto you because dont want you to buy one and the corrosion comes back again but just was thinking that this backplate could stop the corrosion from getting on chips!
 
If it comes back I wont clean it off and then rma it and say this shouldn't be happening. If I sent it back now with it clean they would just fire up the card, and then send it back saying there was no issue.
