Are the Axial-tech fans in the RX 9070 XT significantly different from those in the RX 7900 XT

1. Design and Airflow: Both cards utilize Axial-tech fans, which are designed to improve airflow and reduce noise. However, the RX 7900 XT's fans are scaled up to deliver 14% more airflow compared to standard designs, while the RX 9070 XT's fans have a smaller hub, allowing for longer blades and increased downward pressure, which enhances airflow efficiency without specifying a percentage increase over standard designs[1][3].

2. Fan Configuration: Both cards feature triple-fan setups. The RX 7900 XT's fans are part of a larger cooling system that includes a 3.63-slot design, which is more substantial than the RX 9070 XT's 2.5-slot design[1][3].

3. Bearings and Durability: Both cards use dual-ball fan bearings, which are known for their durability and can last up to twice as long as sleeve bearings[1][3].

4. 0dB Technology: Both cards feature 0dB technology, where fans stop spinning when GPU temperatures are below a certain threshold (55°C for both models), and start again when temperatures exceed 60°C, ensuring silent operation during less demanding tasks[1][3].

5. Cooling Performance: The RX 7900 XT's larger heatsink and more extensive cooling system are designed to handle the higher thermal demands of the RDNA 3 architecture, while the RX 9070 XT's cooling system is optimized for its specific power requirements and form factor[1][3].

In summary, while both cards use Axial-tech fans with similar technologies like dual-ball bearings and 0dB operation, the RX 7900 XT's fans are part of a more robust cooling system designed for higher performance and power consumption, whereas the RX 9070 XT's fans are optimized for efficiency and compactness.
