SAPPHIRE RX 5700 XT Pulse 8GB 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 the 3DMark Fire Strike Ultra stress test for 30 minutes. An idle reading comes after leaving the system on the Windows desktop for 30 minutes.

As for noise levels, here we can see a notable difference between the Performance and Silent BIOS. The Performance mode is certainly not loud – fan speed hit 50%, or around 1600rpm – but it is audible and you can definitely tell the difference when engaging the Silent BIOS. There, fan speed dropped to around 1230rpm, or 38%, making it one of the quietest cards on our chart.
