Has anyone heard of this? My GPU is fairly new, just over 2 months old. It has never seen temps over 70c and I keep my system extremely clean and well protected tongue.gif. I just noticed this sticky residue on the back of the GPU. it looks like if I took a sticker off the back of the GPU and it left behind this sticky stuff. It isn't sticky persay but more tacky.
All I thought was that stuff used during soldering flux or flax or what ever. I don't think its going to hard anything, its just unsightly. So does anyone have a clue what this is? How could I clean it off safely? Thanks.
