Palit RTX 4070 Ti GameRock OC Review

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 for 30 minutes.

As for noise levels, we already mentioned how similar the Performance and Silent BIOS modes are. As it turns out, we saw the Performance BIOS run the fans just 1% faster under load, with speeds around 1320rpm, compared to 1275rpm when using the Silent BIOS. Such a small difference was imperceptible to my sound meter, but both are still very good results, hitting 35dBa.
