From “Fan Count Specs” to “Thermal Confidence in Real Builds”
High-Density Cooling Layout for Modern Gaming Hardware
The A-425B supports up to 10 × 120mm fans, allowing brands to configure different airflow strategies:
- Front intake optimization for high-TDP GPUs

- Graphics card clearance:up to 380mm
- CPU cooler height:up to 168mm
These dimensions ensure compatibility with most mainstream and high-end gaming components used in North American and European markets.
B2B value:
Fewer fitment issues mean lower RMA rates, fewer negative reviews, and faster assembly for system integrators.
Practical Front I/O for Market Expectations
- USB 3.0 ×1
- USB 2.0 ×2
- HD Audio / Mic
This configuration meets current mainstream channel requirements without increasing BOM complexity.
B2B value:
