AORUS GeForce RTX 5080 MASTER 16G sits at the top of Gigabyte’s air-cooled RTX 5080 lineup. The side LCD on the cooler shroud stands out, and the box even includes a fourth fan. Build quality is robust and premium, and the stock overclock is higher than you usually see on OC variants. Not everything is perfect, though—the out-of-the-box fan tuning could be better, and those extras do push up the price.
Fan behavior and noise levels
Fan speed can be set between 30% and 100%, which yields roughly 1100–3000 rpm (29.1–46.8 dBA). At the minimum setting, the sound level meter read 32.1 dBA, which is audible at close range.
At higher speeds, large fans tend to show noticeable fluctuations in noise.
Cyberpunk 2077, RT Medium, 3840 × 2160 (P mode)
The first set of measurements comes from the Cyberpunk 2077 benchmark using the RT Medium preset at 3840×2160. It consists of eight loops. The final run is highlighted, and the average for the warmed-up card is calculated from that run.
The GPU is fully utilized in this test, and the card is pushed up against its power limit.
Once warmed up, the GPU clock ranges from 2895 to 2917 MHz, with an average of 2907 MHz.
The card’s power draw, based on monitoring (light-green series), hovers around 350 W. The spec power limit is 360 W. The final chart in this section shows the boost is capped by that limit, in line with every RTX 5080 I’ve tested.
The dark series shows total system power measured with a UT71E multimeter. Under load, the system averaged 491.1 W, which is higher than the other models.
The average GPU temperature peaked at 62.7 °C over the measured interval, with memory reaching 66,5 °C.
The massive heatsink has high thermal inertia, and the large fans ramp up gradually as well, so during the ~70-second load of a single loop the card doesn’t reach its peak temperature.
