Above, the IDLE (desktop mode) results where the GPU hardly has to do anything.

Roughly the same proximity you'll have from a PC in a real-world situation. 75cm away from the setup, above an example photo.įor each dBA test we close the PC/chassis and move the dBA gun 75 cm away from the PC. Considering that's not where your ear is located, we do it our way. Some even place the dBA meter 10cm away from the card. There's a lot of differences in measurements amongst websites. Frequencies below 1kHz and above 6kHz are attenuated, whereas frequencies between 1kHz and 6kHz are amplified by the A weighting. The letter A is added to indicate the correction that was made in the measurement. A specific circuit is added to the sound level meter to correct its reading in regard to this concept. In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. ZOTAC GeForce GTX 770 is a fast card that can prove itself through high clocking. ZOTACs GTX 770 uses a GTX 680 AMP Hot on the heels of the GeForce GTX 780 Nvidia has released a new GPU, the GeForce GTX 770. 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. The GeForce GTX 770 established itself as the weapon of choice for gamers in the 400 segment. This means that the perception of noise is not at all equal at every frequency. The human hearing system has different sensitivities at different frequencies. Examples of Sounds Levels Jet takeoff (200 feet) You could only achieve objective measurement in a sound test chamber. At the bottom left is an indicator that this is a factory overclocked.

Instead of the whites and blues of days past you get a red and black graphic with the Gaming series badge to the right and a tribal dragon graphic on the left. 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. MSI has had a dynamic shift in the packaging it now uses with its Gaming series hardware. We bought a certified dBA meter and will start measuring how many dBA originate from the PC. 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. When graphics cards produce a lot of heat, usually that heat needs to be transported away from the hot core as fast as possible.
