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.

“Asus GeForce RTX 5080 Noctua Editionin melutaso on miellyttävän hiljainen tuulettimien alle 70 % eli 1215 RPM kierrosnopeudella, jolloin ne ovat todella hiljaiset.”

Key features

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.

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.
