The chip I have was made in 2007, no idea how many owners it's had but I know of two people on these forums that have had it. I run mine at 2.7GHz and idle temps are 35c (in a case with very bad airflow) and load temps max out at 60c, usually hits 50c max when gaming. I have an Arctic Cooling Freezer 7 and it does a reasonable job at keeping it cool. Eventually I'll get a better motherboard and clock it to about 3.4GHz with a H50 or something I would think.
