i run a 2000+xp tbred, not sure if urs is tbred or not but either way i use an slk900u heatsink with a vantec tornado fan and at stock speed it never caps 32c even under prime95, slk800 is a good choice as well and much cheaper, and just in case u want to overclock both these HS will do it, i took mine as far as 185/10.5 and 2.0vcore without ever going over 40c under prime95
