Graphics Card Acoustic Levels

Graphics Card Acoustic Levels

When graphics cards produce a lot of heat, usually that heat needs to be transported away from the hot core as fast as possible. Often you'll see massive active fan solutions that can indeed 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 extremely subjective. We bought a certified dBA meter and will start measuring 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 it would be 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 in regard to this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction that was made in the measurement. Frequencies below 1 kHz and above 6 kHz are attenuated, whereas frequencies between 1 kHz and 6 kHz are amplified by the A weighting.


Examples of Sounds Levels

Jet takeoff (200 feet) 120 dBA  
Construction Site 110 dBA  Intolerable
Shout (5 feet) 100 dBA  
Heavy truck (50 feet)  90 dBA  Very noisy
Urban street  80 dBA  
Automobile interior  70 dBA  Noisy
Normal conversation (3 feet)  60 dBA  
Office, classroom  50 dBA  Moderate
Living room  40 dBA  
Bedroom at night  30 dBA  Quiet
Broadcast studio  20 dBA  
Rustling leaves  10 dBA  Barely audible

Once the card is in a fully stressed status (in-game) it touches 36 maybe 37 dBA which means the card is performing at a close to silent acoustic level. There was no coil whine that we could hear that bothered us. Inside a chassis, you'll be hard-pressed to actually hear it.
