wow that black thing is that burn mark?

If those oil come out from GPU mean the GPU going to hv problem soon . I hv few GPU with such condition eventually die off , pls take note .

Its not "normal" for them to leak, its just not really a problem. The occurence of thermal pad leaks is probably less than 1 in 3 or 1 in 4 gpu's in this space, and almost entirely related to heat cycling and/or exposure to higher heat levels (70c+ as an example). It also seems prevalent in certain manufacturers. EVGA, ASUS, and Gigabyte all seem to encounter this "issue" more commonlly, however, do not exhibit such signs if kept "cool" (62c or less) with a fairly consistent temperature range. Conversely, I've never even seen an MSI card that was remotely taken care of exhibit the same leakage. Not to say that MSI is better, I think it just speaks to EVGA, ASUS, and GIgabyte using a different material for their thermal pads all together. EVGA especially since their cards are far and beyond the most common leaks.

They are from your fluid sleeve bearings from your dying GPU fans. Once it dries out, you sill start hearing louder noise from your fans. This will then develop to grinding on the bearings and eventually the fan failing.

Tat is the oil/glue to protect pcb/soldering which is clearly showing on ur pcb board, u may go check how tech repair gpu in utube , thy will put on tat layer on pcb which mean if the card has tat kind of oil most probably hv bad overheat issue . New gpu wont hv tat oil on pcb board for sure , it is up to buyers / viewers to make decision
