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☌. For example, reducing the GPU voltage by around 100mV can drop the GPU temperatures by several degrees and thereby widen the thermal margin to slow the fans down even further.
Reducing the thermal output of the card, undervolting can make it possible to let the card run even quieter. When running the fans at their maximum speed, as it might be required in worst-case situations such as when fully stressing the card in poorly ventilated cases or with very high ambient temperatures, the reduction in noise levels is as big as 14.9 dB(A):Īt medium fan speeds (70% PWM), the Noctua Edition runs 16.8 dB(A) quieter while being fractionally hotter (0.8☌):įor 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. This, in return, enables it to operate with slower fan speeds and, combined with the class-leading efficiency of the NF-A12x25 fans, to run quieter than any other air-cooled card in its class. While the heatsinks of the RTX 3070 and RTX 3080 Noctua Edition have already been tailored in aspects such as size and heatpipe layout in order to make the most out of the Noctua NF-A12x25 fans’ superior aerodynamic performance, the heatsink of the RTX 4080 Noctua Edition has been redesigned from the ground up to achieve maximum thermal efficiency:īy adding a vapor chamber and using its superior heat-spreading capabilities to transfer the thermal energy to five instead of two 8mm heat pipes (plus three instead of six 6mm ones), the Noctua Edition provides significantly better cooling performance than the original TUF Gaming GeForce RTX 4080. “The first two Noctua Edition graphics cards were a resounding success, so we’re proud to continue our partnership with ASUS”, says Roland Mossig (Noctua CEO), “Like with the previous Noctua Edition cards, we’ve closely cooperated with ASUS to create the quietest card in its class, bringing our signature low noise levels to the GeForce RTX 4080 series.”
Once again, we have combined our expertise with Noctua’s mastery of low-noise cooling to create a graphics card that offers an unparalleled experience without compromising on noise levels, reflecting the strength and innovation of our collaboration,” said Kent Chien (Corporate Vice President and General Manager of the ASUS Multimedia Business Unit).
“Building on the success of our previous collaboration, we are delighted to present the ASUS GeForce RTX 4080 Noctua Edition.
