When comparing the Axial-tech fans in the RX 9070 XT to those in the RX 7900 XT, several factors come into play, including design improvements, noise levels, and overall cooling efficiency.
Axial-tech Fans in RX 9070 XT
The Axial-tech fans in the RX 9070 XT are part of ASUS's advanced cooling system, designed to provide optimal airflow while minimizing noise. These fans feature a smaller hub and longer blades, which enhance airflow efficiency and reduce noise by increasing downward air pressure. Additionally, the 0dB technology allows the fans to stop completely when the GPU temperature is below 55°C, ensuring silent operation during less demanding tasks. This design helps maintain a balance between performance and acoustics, making the RX 9070 XT suitable for both gaming and quiet computing environments[2][7].
Axial-tech Fans in RX 7900 XT
For the RX 7900 XT, ASUS also employs Axial-tech fans, but with slightly different specifications. These fans are scaled up to deliver more airflow, which helps in cooling the powerful GPU. However, the noise level can be higher compared to the newer models like the RX 9070 XT, especially under heavy loads. The TUF Gaming version of the RX 7900 XT, for example, features larger Axial-tech fans that provide increased airflow but may not be as quiet as the RX 9070 XT's fans under similar conditions[10].
Comparison of Noise Levels
In terms of noise levels, the RX 9070 XT generally offers quieter operation due to its refined fan design and the 0dB technology, which allows for silent operation at lower temperatures. The RX 7900 XT models, while effective in cooling, may produce more noise, especially when the fans are spinning at higher speeds to manage the GPU's heat output. Users sensitive to noise might find the RX 9070 XT's fans more appealing for their ability to maintain low noise levels even during demanding tasks.
Overall, the Axial-tech fans in the RX 9070 XT are designed with a focus on both performance and quiet operation, making them potentially quieter than those in the RX 7900 XT under similar conditions. However, specific noise levels can vary based on the exact model and cooling configuration.
