Acoustic and Thermal Results
The Sapphire RX 470 OC 4GB with blower cooler isn’t the quietest RX 470 available but it does the job. The card didn’t go over 79C in our standard testing and the noise profile wasn’t offensive with the clocks left at default. During our overclocking testing that yielded a limited material benefit, the fan had to really wind up to keep the card under 83C.
The overclock was limited to 1282 MHz which translated to an average performance bump of just under 3 FPS in games like Hitman, Ashes of the Singularity and GTA V. For the effort and noise, it wasn’t really worth it. The decibel meter reading was 51dB(A) for the cooler when overclocking.
