Graphics card noise levels
Graphics card noise 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.
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|
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 1kHz and above 6kHz are attenuated, whereas frequencies between 1kHz and 6kHz are amplified by the A weighting.
There are a lot of differences in measurements amongst websites. Some even place the dBA meter 10cm away from the card. Considering that's not where your ear is located, we do it our way. 75cm away from the setup, above an example photo.
For each dBA test we close the PC/chassis and move the dBA gun 75 cm away from the PC. Roughly the same proximity you'll have from a PC in a real-world situation. Above, the IDLE (desktop mode) results where the GPU hardly has to do anything.
One card in a fully stressed status (in-game) reaches roughly 39 dBA. Now that remains very silent. No coil noises or anything either, lovely.
In this review we test the GeForce GTX 780 Ti Gaming edition from MSI. The customized product is equipped with MSI's popular TwinFrozr IV cooler armed two fans. It remains to be quiet and keeps tem...
MSI GeForce GTX 780 LIGHTNING review
We benchmark test and review the MSI GeForce GTX 780 LIGHTNING edition. The MSI team has been hard at work with this product, completely revamping the design, the PCB, the cooler, and tweakability.
MSI GeForce GTX 760 HAWK review
This review will demonstrate the awesomeness that is the MSI GeForce GTX 760 HAWK. The TwiNFrozr IV cooling solution based product is VERY silent but more overly, it the fastest factory clocked GTX 760 we have seen to date.
MSI GeForce GTX 780 Gaming review
We test and review the MSI GeForce GTX 780 Gaming edition. The graphics card comes with a nice factory overclock and the a very lovely TwinFrozr IV cooler that has two silent 90mm fans.
