A maximum of 15,5 db(A) – that’s what how we advertise our Silent Wings 3 140mm fans. But what are decibels? What is the meaning of the letter A? And how does the number 15,5 fit in the bigger picture?
If you put ten Silent Wings 3 fans next to each other you increase the acoustic intensity tenfold while the volume only gets doubled. Which means that the fan noise in itself isn’t the main problem with silence-focused PCs – it’s actually other sources of noise, such as graphics cards, air flow or the electrical whine of coils or capacitors.
