If I recall Anandtech's recent review on the Thermalright Ultra 120 Extreme, and it does not ship with a 939 adapter. You try to buy the adapter from Thermalright, or you could just go with the regular Thermalright Ultra 120, which does come with the 939 adapter. Do keep in mind that the Thermalright Ultra 120 and Extreme do not come with their own fan, so you will need to spring for your own fan in order to keep your processor anywhere near as cool as it is now.
