Features:
The BeamAir is what I would consider a very targeted product when it comes to uses. This isn't something that everyone will have a use for in their case because it is designed for a specific application; to take a fan's air steam and focus it more inline with the blades while increasing the power behind it slightly. Thus, the BeamAir will only be used in applications where you need highly targeted cooling and have the ability to properly install the fan after the BeamAir is attached. Things like a CPU cooler would likely be out of the picture because the fins on a CPU heatsink need as much airflow as they can get, so focusing the airflow will leave some areas uncooled and could possibly slow down overall CPU cooling. A good example of where the BeamAir could be used is on a hard drive cooling fan. If you put it on a 120mm intake fan at the front of your case and put one or two hard drives directly in the airflow you will be able lower their temperature slightly by allowing more air to move over them at a faster rate. Also, using it on a door fan to direct air more towards the CPU would be another example. For mod'ers and die-hard overclockers I'm sure you will be able to find endless uses for a product like this.

Installation:
I figured the best way to truly see the performance of the BeamAir was to install it on a fan with a decent amount of airflow. This would make it easy for me to feel the airflow pattern prior to installation and then again after. Since I had the Scythe S-Flex G laying around from that previous review I decided this would be the perfect fan. I set the BeamAir on top of the fan and carefully pushed it down to secure it in place. Crack. I was surprised to hear that a small crack had develop on all four corners of the BeamAir, so this was obviously not a good fit and I certainly do not consider the Scythe fans to be any larger than a typical 120mm fan. Because of this crack, I was left with a tiny spacing between the fan and BeamAir and it would not perfectly grab around the fan's frame. Grabbing myself a Nexus fan for quick comparison and it fit on just fine. This incident has now greatly reduced the number of applications for the BeamAir by eliminating any Scythe fan users and anyone who has a fan with a similar body frame size! Hopefully this will be taken into consideration for a revision by Nexus, after all they did impress me by releasing a revised NX-8060 power supply that was made even quieter!
