Bora Digital are excellent fans. They are really quiet and provide reliable airflow. The quality and construction is noticeably better than the rest. A high quality plastic frame and two metal plates cover the motor and blades. The front and rear panels are milled from one piece of aluminium. These fans look very beautiful. Performance is top notch. These fans use a fluid dynamic bearing, making them quiet and efficient. They operate in the 900-1800 RPM range and generate 57.97 cfm and 19.4-29 dBA noise levels. They're pretty good with that, at least according to the manufacturer, since I couldn't test those parameters. I have no reason to doubt them. These fans are quiet and powerful. The fan itself can be disassembled for cleaning which is an added bonus. The addressable RGB lighting works well. They are beautiful. You can control them directly from the motherboard if you have a 5V ARGB connector that looks like this.
