All-around Energy Efficiency
With the Energy Processing Unit (EPU), you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode.
Flexible Cooling Controls
Fan Xpert 2+ software provides comprehensive control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.
Precise Digital Power Control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.
VRM Heatsinks and Thermal Pads
The VRM heatsinks with underneath thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.
