RedMagic Cooler Fan 4 Pro - Cooling Fan - Battery protection and heat dissipation management - Black

RedMagic Cooler Fan 4 Pro delivers powerful cooling for mobile gaming with RedMagic ICE 4.0 technology. It cools rapidly, reaching as low as -9°C, and features a 27W cooling power plus a TEC cooling chip to lower phone temperature instantly by up to 30°C, helping protect battery life. The device offers universal compatibility across iPhone (11 and newer with MagSafe), Android smartphones, Nintendo Switch, and iPad. Magnetic mounting provides easy attachment and does not require a MagSafe sticker for supported iPhones; a free magnetic sticker is included for devices without MagSafe. The cooling system uses a high-speed 7-blade fan at 5400 RPM and a 40×40 mm cooling plate for full phone surface coverage, delivering up to 20% higher cooling efficiency. Smart control with variable frequency ensures continuous, efficient cooling, while a transparent mechanical housing with 12 RGB LEDs creates an immersive gaming aesthetic. Noise stays low at 36 dB even at max speed, and the Goper app (Bluetooth, iOS/Android) enables real-time temperature monitoring and AI-powered cooling adjustments.
