They're positioned on the upper left side, so you can access them instantly without tabbing out or taking your right hand off the mouse. Switch on your mic to strategize with your team or turn up the volume to hear every enemy movement in your vicinity without losing focus on the game.


Intelligent Cooling Improves Your Experience

ROG's Intelligent Cooling philosophy mixes the right features and system settings to ensure the best experience for each chassis and components, no matter what you're doing. The Zephyrus M's self-cleaning thermal module ejects dust to improve longevity, dual n-Blade fans spin 83 blades each to increase airflow, and ultra-thin fins expand the surface area for heat dissipation. ROG Armoury Crate software seamlessly switches between operating modes to optimize performance and acoustics for the task.


Comprehensive Cooling Coverage

5 heatpipes snake beneath the surface to pull heat away from not only the CPU and GPU, but also the circuitry supplying them with power. Reducing the temperature of these power components helps improve long-term stability and reliability. The CPU and GPU have their own pipes connected to shared heatsinks that ensure efficient cooling for any workload, including those that light up only one of the two chips.

More Ultrathin Fins

Thermal energy is dissipated by four heatsinks in the flanks. Each one is lined with ultra-thin copper fins as slim as 0.1mm, allowing higher density and lower air resistance than typical fins that are twice as thick. There are 205 heatsink fins totaling 110,000mm2 of surface area, and the ones on the sides are angled slightly toward the back to direct warm air away from your mousing hand.

Self-cleaning Cooling System

Keeping the heatsinks free of debris is critical to maintaining optimal thermal dissipation, so our engineers designed a special anti-dust tunnel that catches and channels particles outside the chassis to prevent them from collecting on the fins. This self-cleaning system helps ensure consistent cooling performance over time, which improves long-term stability and overall reliability.

More Blades Increase Airflow

Slim chassis leave little room for cooling, so we enhance every aspect of the n-Blade fans to maximize airflow. The carefully shaped aluminum intake shrouds use curved edges and raised guides to help the fans draw in more air. Once inside, it's blasted toward the heatsinks by liquid-crystal-polymer blades that are 33% thinner than conventional designs yet still strong enough to spin at high RPMs. The Zephyrus M matches our highest blade density with 83 per fan, improving airflow by up to 15%.

The Right Mode for the Moment

Gaming laptops are versatile enough to tackle a range of tasks, but requirements vary wildly, so Intelligent Cooling adapts accordingly. It automatically switches between operating modes that optimize performance and acoustics for different games and applications. Turbo mode uses the highest fan speed and clocks to sustain maximum speed, Balanced mode adjusts the clocks and cooling to lower noise levels for gaming, and Silent mode runs even quieter for lighter work and entertainment.

I/O Ports

Comprehensive Connectivity

The ROG Zephyrus M has the connections you need for work and play. Alongside the USB 3.2 Gen 2 Type-C™ with DisplayPort™ 1.4 and Power Delivery, there's a Type-A port for ultra-fast data transfers, and two USB 3.2 Gen 1 ports for must-have gear. HDMI 2.0 supports 4K UHD output at up to 60Hz for big-screen gaming and entertainment. Surf the web with 802.11ac Gigabit Wi-Fi, or connect to Gigabit Ethernet to get the lowest latency for serious multiplayer matches and LAN parties.

RangeBoost Technology

Experience a stronger, more stable Wi-Fi connection with ROG RangeBoost technology. RangeBoost's unique algorithm evaluates the signal strength across four internal antennas and intelligently chooses the best pair for the environment. This multi-antenna system can increase Wi-Fi range by up to 30%, which means fewer dead spots and more freedom to connect anywhere.
