Asus say the laptops don't throttle but that could be just marketing tactics
THERMAL: STAY COOL UNDER FIRE
Strix SCAR Edition has an intelligent thermal design that employs heat pipes and dual fans to automatically adjust cooling system for optimized CPU and GPU performance. The specially-crafted venting holes above the keyboard and in the bottom of the laptop allow more intake of cool air. The upgraded 12V fans, which spin at higher speeds compared to traditional 5V blades, drive strong airflow to boost cooling efficiency, so youre free to run the CPU and GPU at full speed without thermal throttling. An additional fan-boost function further increases cooling performance and guarantees total stability during even the most intense battles so youll keep a cool head even under fire!
