I bought this back in Dec, decent paste, didnt have any drop from previous Arctic Silver, which is 5 year old (opened 5 years ago) and still does a great job. It has gotten hard, a bit dried up but still usable if I mash (push it down and twist back n forth) the heat sink on the CPU real good...
MX2 is also a bit hard, i expected it to be a bit more softer, maybe it was sitting on a shelf for a while too...
