I just got my r9 280x from ebay and i saw some wet parts on the back of pcb.. It is slippery, a little bit sticky and smells like an oil.. When i installed the graphics card, it is working great and no problem at all..
Do you know what are these liquid thingy on my graphics card? Should I clean it? And should I worry about it?

He bought it used, not new. I wouldn't be to surprised to find a stain on a used Mercedes(especially if it was a used Mercedes I could afford).

The seller told me that this card was used for less than 1 month x11 mining.. He even include the original purchase receipt with the date on the package as a proof..

To be honest, according to what I see of the stains, it looks more like cooking lard than anything else! XD

Anyways, did your seller include the warranty card with which you can it to the original vendor if anything goes wrong?

on the bright side the staining is on the parts of the board where there arent any components/solder joints... which also leads me to believe it is not flux residue (flux residue shouldnt be sticky/slippery either afaik). try cleaning it with isopropanol or something.

also there seems to be quite a lot of empty screw holes, what sorta cooler does it have on it?

No. The warranty covers defects, not cosmetic issues or damage by the user.

Other forums said that its normal and could be a thermal pad leaking and will not affect the warranty but im still not sure if thats really the problem. I really need your help coz I dont know if it can burn my graphics card on the next few days.. As of now, my card is working great, doesnt exceed 75 celcius on full load..






I think the oil is coming from under the metal bar..

thermal pad leakage seems very plausible, did little googling and found for example this thread
http://forums.evga.com/GTX-580-back-plate-thermal-pad-leaking-m1262613.aspx
and that metal bar is cooling the vrms so it will have a pad underneath it, so that is likely the source of the oily stuff.

also those new images you posted show some flux residue as well, white powder like stains... 2 separate things going on it seems, neither should really be anything to worry about :)

Thanks for clearing that up.. I was really worried about that and the card was about to be replaced by the seller.. The seller was worried too because he sold almost 5 cards with the same issue..
Could overheating be the cause of those oils coming from the thermal pad?
By the way, what can i use to clean those oily stuff?

Well if that Jacob guy at evga says it is normal I dont think overheating comes into consideration since overheating wouldn't be normal... Maybe that is normal 'feature' for some type/model of thermal pads... (thou I haven't personally ever seen it)

You could use isopropyl alcohol, it is widely used in the industry to clean the boards during manufacturing.
