The PRIME B860M-A motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.

4-Pin PWM/DC Fan

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

AIO Pump Header

A dedicated PWM/DC header supports self-contained water-cooling setups.

VRM Heatsinks and Thermal Pads

The massive VRM heatsinks and essential thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.

Multiple Temperature Sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ lets you to map the temperature of supported ASUS graphics cards to optimise cooling for GPU- and CPU-intensive tasks.

M.2 Heatsink

One M.2 heatsink takes care of the M.2 slot, preventing throttling that can occur with M.2 storage during extended transfers.

Passive Chipset Heatsink

An aluminium passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the build-up of dust and debris.

Smart protection

A dedicated integrated circuit protects each fan header from overheating and excess current.
