We take our noise measurements with the sound meter positioned 1 foot from the graphics card. I measured the noise floor to be 32 dBA, thus anything above this level can be attributed to the graphics cards. The power supply is passive for the entire power output range we tested all graphics cards in, while all CPU and system fans were disabled. A reading under load comes from running Cyberpunk 2077 for 30 minutes.
Similarly, noise levels are a touch lower for the 4060 Ti as the fans were able to operate at a lower speed than the 4070 – 1440rpm for the 4060 Ti, compared to 1560rpm for the RTX 4070. In other words, both are very quiet cards, but the 4060 Ti is just a smidge easier on the ears.
