You didn't mention what computer they are for, what proc you have, whether you overclock and how good an airflow design your case has. Tough to give any input when you didn't give anything to go on. They are high quality fans, quiet, and suitable for light use. Only you know how they're going to be used. They are low output so it may make sense if you ADD this fan to a case and not replace a higher cfm. I have never been satisfied with this fan in any of my computers because of the low airflow. I also use my computers at near 100% cpu useage all the time and therefore create a lot of heat. If you only web surf and have a celeron, it may be ok. You decide. You want a quiet fan, get it. If you need to move more air, get something else.
