RedMagic is taking smartphone cooling to the next level. At its recent Shenzhen conference, the company unveiled what it calls the world’s first active liquid cooling system designed for phones—a setup that borrows tricks from gaming PCs and AI servers. The goal is simple: keep performance steady even under heavy loads, without the throttling that tends to hit after a few minutes of intense gameplay.
Unlike the vapor chambers most phones use (which are technically passive systems), RedMagic’s new setup actually circulates coolant through a tiny ceramic micropump. The liquid moves heat away from the chipset and toward a fan-cooled radiator, combining both liquid and air cooling in what the company calls a “dual-track” design. It’s a big engineering challenge, and RedMagic claims it took “thousands of design iterations to reach the final design.”
The pump itself uses piezoelectric ceramics, and the internal coolant channels are laser-cut at the micron level to ensure smooth flow. The fluid—an antifreeze-grade fluorinated liquid—can handle extreme temperatures from –40°C to 70°C, offering stability similar to what’s used in high-end AI servers. To make it durable, RedMagic says it employed low-temperature bonding and anti-puncture membranes, helping the system pass tens of thousands of drop tests without leaks or failures.
You’ll first see this in action on the upcoming RedMagic 11 Pro series, powered by Qualcomm’s new Snapdragon 8 Elite Gen 5 chip. In internal tests, the phone reportedly ran Wuthering Waves at ultra-high graphics and 90fps for two straight hours without dropping frames. According to the brand, the 11 Pro series will support over 200 titles optimized for 2K resolution and 144Hz displays at launch.
RedMagic’s motto is “Win More Games,” and this might be the hardware that makes it possible. As mobile gaming continues to blur the line with desktop-level experiences, active liquid cooling could become the next big leap. For now, it’s RedMagic leading that charge—and keeping things cool while doing it.
