ASRock RX 5700 XT Taichi X 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 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.

When we get to noise levels, we can see one of the main downsides to using the OC BIOS – it is a fair bit louder than the other partner cards we have reviewed so far. With noise levels peaking at 46dB, the card is certainly audible and is getting to what I would call ‘loud' territory. It's nowhere near Radeon VII or Vega 64 levels of noise, but it's an audible card that you will hear when it is under load.

The Silent BIOS does much better here, with noise levels reaching just under 41dB, which is a very noticeable difference versus the OC BIOS. To achieve the lower noise levels, the Silent BIOS runs the fans at around 1700rpm, or 48%, when the OC BIOS runs the fans at 2030rpm, or 58%.
