The Noctua-cooled card has two NF-A12x25 PWM 120mm and an optimized heatsink with a vapor chamber and a total of eight heatpipes. The Noctua edition is said to produce just 33.7dBA at maximum fan speed, a massive difference versus the 48.6dBA of the stock model, while delivering comparable cooling performance.
Following the resounding success of 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 award-winning NF-A12x25 PWM 120mm units and to a more elaborate, tailored heatsink with vapour 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.
