Well-built fan with a pleasant acoustic character. Although Noctua is championed as the king of silent fan operation, there are more noise-effective options out there, like Enermax's less expensive Twister Pressure. Still a great fan tho.

I keep thinking: "Is this thing even on?" I seriously don't hear it even at full speed. Fantastic.

Awesome performance > ugly colour. Rear exhaust fan.

Based on the reviews I've read about this case fan, it is great for exhaust and I think the rear needs a really good case fan to remove all the heat in the case. Comes with 2 adapters as well, ultra-low-noise (700rpm) and low-noise (900rpm). At default, the speed is at 1200rpm. Currently using low-noise for minimal noise as the weather is cold in where I live. Might have to remove the adapter once summer arrives. Hence, I've placed the stock fan to the front to have 2 intakes for positive airflow.
