"A few years ago a friend of mine brought his computer over to my house, needed some work and parts and when he turned it on it sounded like a small airplane taking off. You could hear this thing on the second floor of my house, that’s how loud it was. That was ridiculous in my opinion, you don’t need noisy and loud fans to have a cool system. Personally I must have a quiet system, but I don’t sacrifice performance for low noise levels. Noctua is one of the top companies when it comes to keeping your computer cool, they’re always innovating and improving on their designs and they’ve sent me over their latest 120mm cooling fan for review, the NF-S12A PWM. This fan is 120mm in size and has a maximum speed of 1200rpm, but you can use the included adapter to lower the speed to only 900rpm. I’ve put the NF-S12A up against another Noctua fan that runs much faster at 1500rpm, and I was surprised by the results and I think you might be too. Read on to learn more… "
