If you want to stick to forced-air cooling (i.e., normal) go for a nice solid brute-force HSF (i.e., massive CFM/pressure) .. if the noise bothers you, a fan controller can quickly resolve that issue
Ive got the Volcano11+ on my XP2800 at home but a much better cooler is the Polo735 (it's based off the Volcano12+) and it doesnt cost that much more (if even). This is in no way to say that the Volcano11 isnt up to the task
