Keep Your Phone Cool When Performance Matters Long gaming sessions, live streams, high-resolution recording, and extended video playback can generate enough heat to slow down your smartphone. The Ventaron Frost Blade B3 is a powerful 25W semiconductor phone cooler designed to rapidly draw heat away from your device and help maintain smoother, more stable performance. Fast 25W Semiconductor Cooling A high-performance Peltier TEC cooling chip works with a 1070 aluminum heat sink and large 2,298 mm² cooling surface for rapid heat transfer. Under controlled no-load laboratory conditions, the cooling plate can achieve a temperature drop of up to 45°C and reach as low as -19.5°C. Actual cooling performance may vary depending on ambient temperature, phone model, case, application, and power source. Powerful Airflow with Low Noise The 5500 RPM seven-blade fan, 3D air duct, and airflow-straightening ring quickly move heat away from the cooling system. This stable fan structure delivers strong airflow while operating at 25 dB or less under controlled test conditions, making it suitable for gaming, streaming, recording, video calls, and everyday entertainment. Three Adjustable Cooling Levels Choose from three cooling levels to match your activity. Increase cooling power during intensive mobile gaming or high-resolution recording, or select a lower setting for video playback and everyday use. Dual NTC temperature monitoring helps regulate operation and protect the cooling system. Magnetic and Clip-On Mounting The built-in magnetic system attaches directly to MagSafe-compatible iPhones. For Android smartphones, non-magnetic phones, and compatible cases, use the included magnetic sheet or detachable back clip. No app, Bluetooth connection, or complicated setup is required. Compact Design with Dynamic RGB Lighting Weighing only 74 g, Frost Blade B3 delivers powerful cooling in a compact, portable design. Four selectable RGB lighting effects add an immersive visual accent to your gaming or streaming setup.
