Asus has unveiled a new graphics card for Noctua aficionados - the ASUS GeForce RTX 3070 Noctua Edition - featuring none other than Noctua fans.
The partnership between Asus and Noctua sees the incorporation of a pair of state-of-the-art NF-A12x25 fans to move air over a massive 2.3-slot heatsink. To ensure high cooling performance and low noise levels while making enough room for the 120 mm fans, the card's total volume was expanded to occupy 4.3 slots of space.
According to Asus, the Noctua Edition produces a 10 dB lower sound pressure level when
controlling for the same power limit, ambient temperature, and thermal junction temperature compared to the TUF Gaming GeForce RTX 3070 OC Edition. The Noctua Edition has all the signature features that other Asus graphics cards are known for, including a dual-mode BIOS switch and Auto-Extreme assembly technology.
Furthermore, it uses an impeller made from Noctua's proprietary Sterrox liquid-crystal polymer, allowing the fan blades to sit only 0.5 mm away from the outer frame. This will increase the fans' efficiency against backpressure by reducing leakage of airflow between the blade tips and the outer frame.
The custom PWM IC uses smooth commutation drive technology to reduce fan noise levels at lower speeds while the flow acceleration channels at the tip of each impeller blade enhance efficiency and lower vortex noise. The inner surface microstructures on the fan frame reduce noise from passing the blades. Additionally, it has soft silicone anti-vibration pads that prevent the transmission of vibrations to the graphics card and on through the case.
