Following the ASUS GeForce RTX 3070 and RTX 3080 Noctua Edition, the Noctua Edition of ASUS’ GeForce RTX 4080 is the third graphics card to feature Noctua fans and a heatsink that has been co-engineered by Noctua. By switching from the stock three slim 110mm fans to two of Noctua’s NF-A12x25 PWM 120mm units and to a more elaborate, tailored heatsink with a vapor chamber and five instead of two 8mm diameter heatpipes, thermals and acoustics of ASUS’ original TUF Gaming GeForce RTX 4080 could be improved significantly for the Noctua Edition, making it the quietest card in its class.
The GeForce RTX 4080 Noctua Edition features a semi-passive fan control setup (ASUS 0dB technology) that can switch the fans off completely whenever the GPU temperature goes below 50°C. This means that in typical configurations with low to moderate ambient temperatures and well-ventilated cases, the card can run entirely passive at lower GPU loads, such as during office productivity tasks, web browsing, or even light gaming. Even at high GPU loads, such as during gaming or benchmarking, the fan speeds will stay extremely low as long as the ambient temperature inside the case isn’t excessive.
In summary, the ASUS GeForce RTX 4080 Noctua Edition is ideal for quiet cooling enthusiasts who demand serious GPU performance without sacrificing silent operation.
