The AVC Z7UB301 heatsink is one of the first stock Socket 754 heatsinks AMD shiped with its processors, and it is currently used with most Socket 939 Athlon64 CPU models too. While its name lacks any mention of 'extreme,' 'whisper,' 'ultimate,' or some other such stereotypical marketing sloganry... it is a damn fine heatsink. That, in spite of its complex alpha-numeric 'Z7UB301001' nomenclature. Asia Vital Corporation (AVC) itself is one the largest heatsink manufacturers in the industry, but primarily so in an OEM capacity. The company produces several models of stock Intel and AMD heatsinks, in addition to a variety of after market models.
