Cooler by design

Prime B450 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.

Multiple temperature sources

Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.

AIO Pump

Dedicated PWM/DC header for self-contained water-cooling setup, is built right in.

4-pin PWM/DC Fan

Each onboard header supports auto-detection of PWM or DC fans.

Smart Protection

A dedicated integrated circuit protects each fan header from over-temperature and over-current.
