Temperatures, Noise and Overclocking
The Aorus RX 580 XTR 8G ran quite cool. The large triple fan design allows for a profile that is less than aggressive side. I found no reason to adjust the fan profile further, even when the card was aggressively overclocked.
Noise is a very subjective thing. While measuring dB level of noise can tell you how loud something is, it does not tell you the quality of the noise. Human hearing is the most sensitive in the 4000Hz range. This is roughly the same pitch as a crying newborn baby or the old adage, nails on a chalkboard. The human brain is wired to react to this frequency range and when we are unable to stop the noise, we become agitated.
For this test, the best case scenario is absolute silence. For the worst case scenario, I use the most annoying sounding and loudest video card I have at my disposal, the Nvidia 7600GT. The Aorus RX 580 XTR 8G was almost silent most of the time. Even under full load, I rarely noticed any fan noise or coil whine coming from the card.
Currently, Wattman is the only overclocking utility I have located that support the RX 580. I adjusted the power target and voltage to the maximum. I tweaked the core speed first and then moved onto the memory speed. After bit of fine tuning, I ended up with +55MHz (1480Mhz) Boost on the core and +620MHz (8620MHz) on the memory. This was an increase of 4% for the core and 8% on the memory. On an average, we saw an increase of around 5% percent increase in frame rates in our suite of benchmarks.
