realme has released a new teaser for a concept phone with an “AC active cooling system.” This “Chill Fan Phone” is being showcased at the company’s 828 Fan Festival. The innovative cooling solution is a significant departure from traditional smartphone thermal management.
A Bold Approach to Cooling

While smartphones with built-in fans are not new—a feature often found in high-performance gaming devices—realme’s latest innovation appears to be a leap forward. The teaser video, shared by the company’s global and Indonesian social media channels, showcases a tiny vent on the side of the phone. In a truly captivating display, this vent is shown blowing out a candle and even pushing a rubber ducky across water, suggesting a powerful, directed airflow.
The “AC” Tech: A Game-Changer for Performance?
The company claims this system can lower the phone’s core temperature by a significant 6°C, which would be a game-changer for mobile gamers and power users. This “AC” technology is not just about moving air; it’s about actively cooling the device, a move that could redefine sustained performance for future handsets. It’s a bold play that challenges the traditional passive and vapor cooling solutions prevalent across the industry.
Beyond the Fan: A Glimpse into realme’s Future
The Chill Fan Phone is a concept device, meaning it may never hit the market in its current form. However, it provides a glimpse into the company’s innovative mindset and its commitment to tackling one of the biggest challenges in modern smartphone design: thermal throttling. By experimenting with an active, “AC-level” cooling system, realme is positioning itself at the forefront of a potential new era of smartphone engineering.
This audacious concept will be officially showcased at the 828 Fan Festival on August 27, where the company is also expected to reveal another technological marvel: a concept phone with an eye-popping 15,000mAh battery. These teasers demonstrate a clear focus on a future where smartphone hardware breaks away from the conventional to solve persistent user pain points.
The big question remains whether this technology is a viable, scalable solution for a mass-market product. But one thing is clear: the company is asking a fascinating question about what’s possible, and the answer could be a lot “cooler” than we ever imagined.
