This is a great fan to have if u want to manually control fan speed via the must have three speed switch. The first setting is practically silent, the middle is pretty quiet too which is what I use. The third setting is a bit loud but in gaming situations it would blend in with the background noise. This fan works great for increasing air intake while keeping two other exhaust fans at normal speed.
Direct replacement for my aging Antec 300 case (but brighter than the original due to the clear housing). One minor gripe is the mounting screws are too small/thin for the fan mounting holes, though reusing the original screws worked.
