What Liquid Cooling on a Gaming Phone Actually Is
Liquid cooling on a gaming phone is a thermal management system that uses moving coolant, internal pumps, a vapor chamber, and an active fan to move heat away from the processor and battery faster than passive metal plates alone. In the RedMagic 11S Pro, this AquaCore Cooling System pairs flowing fluorinated liquid channels with a 24,000-RPM internal fan and a large vapor chamber to control heat from the overclocked Snapdragon 8 Elite Gen 5 Leading Edition. The goal is simple: keep performance high and throttling low during long gaming sessions, even when the screen is pushing a 144Hz refresh rate and the 7,500mAh battery is under load. On paper, this is a multi-layer answer to the age-old gaming phone thermal management problem, but as with any liquid cooling phone, the key question is whether it keeps your hands comfortable, not only benchmarks high.
Specs and Cooling Hardware: More Than a Simple Vapor Chamber
RedMagic’s latest gaming phone starts with serious hardware: an overclocked Snapdragon 8 Elite Gen 5 Leading Edition hitting up to 4.74GHz CPU clocks, paired with a 6.85-inch OLED screen that runs at 144Hz and a 7,500mAh battery. RedMagic claims the CPU is 19% faster, the GPU 24% faster, and the NPU 39% faster than its previous 10S Pro, so the thermal load is heavier than before. To handle this, the RedMagic 11S Pro stacks several layers of cooling. There is a visible liquid loop driven by piezoelectric ceramic micropumps, tiny internal channels, a sizable vapor chamber, and a high-speed 24,000-RPM active cooling fan. According to RedMagic, this liquid cooling system “improves heat transfer efficiency by up to 50%” and also cools the battery. Compared with vapor chamber only setups on many rivals, this phone leans on active cooling fan performance and physical fluid movement, aiming to turn a niche gaming feature into a mainstream selling point.
Benchmarks vs Heat: The Trade-Off of Extreme Performance
Synthetic stress tests show what this liquid cooling phone can do when pushed to its limits. In Geekbench 6, the RedMagic 11S Pro edges ahead of other Snapdragon 8 Elite Gen 5 devices, even outscoring the Galaxy S26 Ultra’s tuned version by about 3% in both single- and multi-core results. In 3DMark Wild Life Extreme, it sustains 77% of its peak score by the end of the stress test, whereas rival gaming phones fall to between 60% and 49%. The trade-off is temperature. Under these intense loads, the RedMagic 11S Pro reaches a peak of 59°C and averages around 49–50°C, which makes the phone uncomfortable to hold for several minutes after the test stops. Even with vapor chamber vs liquid cooling plus fan working together, those are higher temperatures than the roughly 44–46°C peaks seen on competing models that rely on more conservative tuning.
Real-World Gaming in a Heatwave: Comfort vs Consistency
Stress tests are worst-case scenarios, so the next step is real gaming in tough conditions. During an unusual 33°C heatwave, the RedMagic 11S Pro was used for 20-minute sessions of COD Mobile Battle Royale, Asphalt Legends, and Mario Kart Wii via the Dolphin emulator, all with graphics settings pushed high and frame rates targeting above 60fps on the 144Hz panel. With software left in control of profiles and the internal fan, the phone maintained high frame rates without obvious stutter or throttling. After 20 minutes of Call of Duty Mobile, surface temperatures hit around 43°C. That is well below the 59°C seen in synthetic tests, but it still feels clearly warm in the hand and borders on uncomfortable for longer sessions. In other words, the AquaCore liquid cooling system helps sustain performance and delays throttling, yet it cannot rewrite physics: when the chip runs close to desktop levels, you will notice the heat.
Is the $100 Premium Worth It as Liquid Cooling Goes Mainstream?
The RedMagic 11S Pro steps up from the earlier RedMagic 11 Pro by adding visible liquid cooling on top of an already aggressive vapor chamber and fan design, but that upgrade does not come free. Pricing now starts at USD 799 (approx. RM3,680) for the baseline RedMagic 11S Pro and USD 849 (approx. RM3,910) or more for the global configurations, which is around USD 100 (approx. RM460) higher than the previous RedMagic 11 Pro’s launch price. In return you gain stronger sustained performance, a 7,500mAh battery, 80W wireless charging, and one of the most elaborate gaming phone thermal management systems available. However, our testing shows that the phone still reaches 43°C in demanding games and up to 59°C in stress tests, so the upgrade favors raw power over cool-touch comfort. As more brands adopt liquid cooling and active fans, the RedMagic 11S Pro stands out for speed, but not for staying cool in your hand.
