ROG PHONE CHILL CASE
Stay cool, sound great

Leveraging the ROG Phone’s advanced cooling technology, the ROG Phone Chill Case is the world’s first phone case with an integrated liquid cooling system, along with our unique Audio Redirect technology for front-facing sound. Enjoy immersive audio and keep your phone cooler for a comfortable, uninterrupted gaming experience.
Thermal
Chill out the heat
The ROG Phone Chill Case features a new Composite Vapor Chamber (CVC) material that efficiently dissipates heat away from your phone, reducing the temperature around the SoC by up to 17%1. This CVC is made of PC and PMMC materials2, offering thermal performance almost as good as copper but with zero impact on 5G and Wi-Fi connectivity.
Whether you’re in the middle of an intense battle or pushing your phone to the limits with demanding games, our Chill Case keeps your ROG Phone 9 Series running smoothly and comfortably in your hand.

Sound
Immersive Front-Facing sound
The ROG Phone Chill Case also enhances your audio experience with our innovative Audio Redirect technology. Designed with precision-engineered sound channels, this feature redirects audio from the bottom speakers to the front, delivering a richer, more immersive sound experience.
Whether you’re gaming, watching videos, or listening to music, Audio Redirect ensures that every sound is clear and directed towards you, creating a more engaging and dynamic experience.
