Building a powerful PC takes time and effort. It is usually very difficult to get everything to go your way. Many folks with high-end PCs complain about their machines making too much noise. After all, you have to cool down your computer somehow. The Noctua NF-F12 Noise Canceling PC Fan may be what you need. It is a 120mm PC fan that comes with the RotoSub Active Noise Cancellation technology. It can reduce fan noise by up to 20dB. Interested? You will have to wait till Q3/Q4 2013 to get this.
