Summary: Excellent fan. Size is 80 x 80 which is a standard size used by most systems. The 30dba is a bit loud, but still manageable for anything but a multimedia box. Blue casts a beautiful glow in the case. The quality of the fan, should provide a few years of use.
Summary: For a gaming case or a home system, this fan is affordable and it has dual bearings for quieter and reliable cooling. The fan puts off a good mid blue. It is pretty bright, but it looks amazing.
