The XP-120 is awesome, but completely over the top for your processor. I would recommend the less expensive, and more likely to FIT, XP-90C by Thermalright, with a Panaflo MA1 fan attached. FrozenCPU has the best deals on them ($10 cheaper than NewEgg), and with the Panaflo with 3 pin power adapter option (Panaflos do not come wired, that is an option, or you can solder it yourself) you come to about $55 without shipping. Add in AS5, and you have a awesome heatsink setup.
