What is this oily residue?
I saw this a month back and cleaned it with 99 IPA and it was gone. And today I see it came back.
Google says its thermal pad oil secretion.
I am 100% certain its not capacitor juice as all capacitors in that area are intact and can be seen from both side.
GPU is a 1660s from Zotac.



Btw here is my GPU layout from inside.
Picture by hardwaretimes.
The picture has a missing capacitor circled in red which my GPU has as I can see the legs.

Thermal pads is a likely source. Thermal compound. Solder paste (though I would expect that on the other side of the board) Capacitors can certainly leak, and still function for a long time, though I don't think so in this case.

If there are no issues, clean it up again, and just keep using it.
