Acoustic and thermal performance
Acoustic performance - Fans Noise Levels
Processors and graphics cards can produce a lot of heat that must be transported away from the hot core as quickly as possible. You’ll often see massive active fan solutions that can get rid of the heat, yet all the fans these days make the PC a noisy son of a gun. Do remember that the test we do is highly subjective. We bought a certified dBA meter and will measure how many dBA originate from the PC. Why is this subjective, you ask? Well, there is always noise in the background: from the streets, from the HDD, PSU fan, etc., so this is, by a mile or two, an imprecise measurement. You could only achieve objective measurement in a sound test chamber.
The human hearing system has different sensitivities at different frequencies. This means that the perception of noise is not at all equal at every frequency. Noise with significant measured levels (in dB) at high or low frequencies will not be as annoying as when its energy is concentrated in the middle frequencies. In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. That’s why we measure the dBA level. A specific circuit is added to the sound level meter to correct its reading regarding this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction made in the measurement. Frequencies below 1 kHz and above 6 kHz are attenuated, whereas the A-weighting amplifies frequencies between 1 kHz and 6 kHz.
There are a lot of differences in measurements between websites. We measure noise levels in a completely enclosed and closed room. The lowest dBA level we can measure in this room without equipment activated is roughly 30 dBA. We measure the noise 30 to 40cm from the side panel.
