I have an Antec sx1030b case. I was overclocking this computer, so i had alot of loud high performance fans in it, 4 x 80 high-output sunon and a 80mm delta... Well i am giving this computer to my brother and where he is putting it it needs to be quiet. My question is, what 80mm fan is quiet and still has good performance? Also if i am putting a lower cfm fan on the 80mm convertor on my processor, should i take it off and put a 60mm on? If so what 60mm fan is what i am looking for? Also, the computer will not be overclocked anymore... 
Thanks,
Brad
