Review on UpHere 3-Pack 120mm Computer Case Cooling Fan - Long Life Cooling Fans for Computer Cases: 12BK3-3 by Jack Duncan

These fans are an ideal inexpensive alternative to more expensive brand name fans (Corsair, Thermo-Take, be-quiet). An alternative to cheap supply and exhaust air fans. I tested them on a second system which was a test build to see how they hold up. Pretty good if you ask me. Very quiet and good airflow. $12 for three 120mm fans is a steal. Sure, they're not PWM, but running at 12V (1200rpm) is still quiet. They're not even noticeable when you're wearing headphones. They were so good I bought another set to increase airflow on the second build. Some may be put off by the unfamiliar branding (Uphere) but so far they're doing a great job. Take my word for it or not. You just have to try it yourself.
