The GameCool 5 cooling system on ROG Phone 5 Ultimate has an optimum thermal structure featuring a centered CPU with the battery split into two parts, one located on each side of the CPU. This ensures that the heat generated by the CPU is transferred to all the edges and corners of the chassis simultaneously for higher thermal efficiency. The reshaped vapor chamber and extensive graphite sheets also help to spread the heat evenly across the device to reduce heat build-up in the middle.
The all-new AeroActive Cooler 5 is completely revamped. It now intakes and expels an incredible amount of air directly on the center of the phone — right where the CPU is — to deliver an unbelievable 10°C drop in the CPU temperature.
