Quiet CPU FAN - 30 dbA on full load?(AM3+)

Is it possible to get these?

I am currently in the process of getting a real quiet computer, and need a new fan.

My case is Cooler Master Elite 430.


My budget is whatever i have to spend.

Ok so you want case fan or cpu fan? Both are very possible and can get even quiter then that but if you want for the cpu you would need to get and aftermarket cooler. 


Could i just get a large thermal mask, and just buy a aftermarket cooler or something?
