Cool to the Core

Prime B460 series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

Cooler by Design

Prime B460 series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

Multiple Temperature Sources
Smart Protection
4-Pin PWM/DC Fan

Each header can be set to monitor and react to several thermal sensors, and via Fan Xpert 2+ you can even assign a sensor to monitor the temperature of supported ASUS graphics cards — for optimal cooling during GPU- or CPU-intensive workloads.
A dedicated integrated circuit protects each fan header from overheating and overcurrent.
Each onboard header supports auto-detection of PWM or DC fans.

Build on a Solid Foundation

Prime B460 series is built to handle the additional cores and increased bandwidth of 10th Generation Intel^® Core™ processors. A B460 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.

ASUS OptiMem

Revisions to the motherboard's trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS OptiMem technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.

Top layer – ground ring to prevent lateral interference

ASUS OptiMem benefits:

Improved memory stability and compatibility
Allows lower memory latencies at equivalent voltages
Improved memory frequency margin

Motherboards with OptiMem technology were tested with Synopsys HSPICE simulation software
