True to the legacy of the ASUS x Noctua series graphics cards, the ASUS GeForce RTX 5080 Noctua Edition leverages the power of Noctua’s latest flagship fans and a fully custom-engineered heatsink to achieve state-of-the-art quiet cooling efficiency. The ASUS GeForce RTX 5080 Noctua Edition utilises three of the new NF-A12x25 G2 fans and a fully custom-developed, thoroughly optimised heatsink that combines an extensive vapour chamber with seven 8mm and four 6mm heatpipes. The fans are offset in speed in order to avoid undesired acoustic interaction phenomena due to beat frequencies such as periodic humming or vibrations. This highly sophisticated cooling setup enables the ASUS GeForce RTX 5080 Noctua Edition to run significantly quieter than ASUS’ TUF Gaming or ROG Astral models at the same temperatures. In sum, the ASUS GeForce RTX 5080 Noctua Edition is an outstanding choice for demanding gamers or content creators who are looking for a GPU that combines excellent performance with superb quietness of operation. The card occupies 4 slots (80mm), with dimensions of 385mm in length and 151mm in width, weighing in at 2.6kg.
Ever since the first ASUS GeForce RTX 3070 Noctua Edition saw the light of day, ASUS x Noctua GPUs have consistently delivered class-leading quiet cooling and pushed the limits in terms of performance-to-noise efficiency. After the RTX 3080, 4080 and 4080 SUPER models, the ASUS GeForce RTX 5080 Noctua Edition continues this legacy of acoustic excellence.
Triple NF-A12x25 G2 fans
Integrating three of Noctua’s latest, state-of-the-art NF-A12x25 G2 fans, the ASUS GeForce RTX 5080 Noctua Edition is the first gaming GPU that utilises a triple 120x25mm cooling setup. Thanks to the NF-A12x25 G2’s superior performance-to-noise ratio, this enables it to set a new benchmark in its class.
Speed-offset for optimal acoustics
For acoustic fine-tuning, the three NF-A12x25 G2 fans are slightly offset in speed (+/-50rpm) in an PPA/PPB/PPA pattern. This speed offset helps to avoid undesired interaction phenomena such as periodic humming or vibrations due to beat frequencies .
Custom-designed heatsink
The heatsink of the ASUS GeForce RTX 5080 Noctua Edition has been custom-designed and thoroughly optimised to fully utilise the pressure capacity of the NF-A12x25 G2 fans. With a large vapour chamber, seven 8mm and four 6mm heatpipes as well as an extensive, densely packed fin-stack, it provides a massive upgrade over the heatsinks of previous Noctua Edition GPUs.
Phase-change thermal pad
The ASUS GeForce RTX 5080 Noctua Edition uses a premium grade phase-change thermal pad, which combines outstanding thermal performance with superior long-term stability. Avoiding the pump-out and dry-out effects that can occur on GPUs with regular thermal pastes, this guarantees that the card will keep running cool and quietly for years and years.
Quiet BIOS by default
The ASUS GeForce RTX 5080 Noctua Edition features a dual BIOS that enables customers to switch between a performance profile that provides the lowest possible GPU temperatures and a default quiet profile that’s optimised for superior acoustics.
ASUS GPU Tweak III
For enthusiast users who want to take things one step further, the included ASUS GPU Tweak III software provides extra possibilities such as setting custom fan curves or undervolting, which can make it possible to let the card run even quieter due to lower GPU temperatures.
Semi-passive cooling
Thanks to a semi-passive fan control setup that can switch the fans off completely whenever the GPU temperature goes below 50°C (ASUS 0dB technology), the card can run entirely passive during office productivity tasks, web browsing, or even light gaming when using well-ventilated cases at low to moderate ambient temperatures.
