Fan Noise

In past years, gamers would accept everything for a little more performance. Nowadays, users are more aware of their graphics card's fan noise and power consumption.

In order to properly test how much noise a card's fan emits, we use a Bruel & Kjaer 2236 sound-level meter (~$4,000). It has the measurement range and accuracy we are looking for.


The tested graphics card is installed in a system that does not emit any noise on its own, using a passive PSU, passive CPU cooler, passive cooling on the motherboard, and a solid state drive. Noise results of other cards on this page are measurements of the respective reference design.

This setup allows us to eliminate secondary noise sources and test only the video card. To be more compliant with standards like DIN 45635 (we are not claiming to be fully DIN 45635 certified), the measurement is conducted at a distance of 100 cm and 160 cm off the floor. Ambient background noise inside the room was well below 20 dBA for all measurements. Please note that the dBA scale is not linear but logarithmic. 40 dBA is not twice as loud as 20 dBA since a 6 dBA increase results in double the sound pressure. The human hearing perception is a bit different, and it is generally accepted that a 10 dBA increase doubles the perceived sound level. 3D load noise levels are tested with a stressful game, not with Furmark.
Idle fan noise using the stock BIOS is quite high with 30 dBA, even higher than the NVIDIA Founders Edition, and fan stop is missing, too! The good thing is that ASUS included a secondary "quiet" BIOS with their card which enables the highly sought after fan-stop feature.

During gaming with the default BIOS, the card emits roughly the same noise level as the Founders Edition, which is, again, not impressive at all.

However, after switching to the "quiet" BIOS, the numbers are mighty impressive indeed. With just 31 dBA, the card is unbelievably quiet for its performance class. I just wonder why ASUS didn't make the "quiet" BIOS the default, as 75°C is fine as well. I guess they sought to "wow" people with the temperature of their stock BIOS, which looks quite nice at 65°C, but does little else for you. There is no difference otherwise, between 65°C and 75°C.
