Spectral analysis of noise
BeQuiet!, which I probably don’t need to introduce here, launched the top-of-the-line Dark Rock Elite cooler early this year. Along with it, the Dark Rock Pro 5 was also released, but it has remained somewhat hidden in the shadow of its elite sibling, which I would like to correct today. I firmly believe that the fifth gen of the Dark Rock Pro will successfully build on the previous versions, which have always been renowned for their uncompromising cooling performance and quiet operation.
Spectral analysis of noise
A spectral analysis of the noise cannot be missing either. This is a simple analysis at noise levels of 39 dBA, 45 dBA and at maximum speed of the cooler. For the analysis I use the UMIK-1 microphone from miniDPS in conjunction with True Audio’s TrueRTA application. The resolution of the analysis is 1/24 of an octave and the shape of the spectrogram is an average of 100 samples acquired over 20–30 seconds.
