have a evga gtx580
imagine looking at the gpu from the top. you can see the top. about the middle of the card it looks like there's some oil-like substance there. anyone know what i mean? should i upload a picture?
the gpu idles at 48-50C which i think is too high. (ie: just sitting in windows)
 
does evga provide any sort of testing program that checks the gpu's health? i'm not talking about info programs or benchmark programs. i mean tools.
