Mobile Phone Semiconductor Magnetic Heat Sink RGB Silent Cooling Fan with Intelligent Temperature Display Lights Off Mode for Gaming Smartphones

This semiconductor magnetic heat sink attaches securely to gaming smartphones using strong magnets, providing active cooling through a silent fan and thermoelectric cooling module. The built-in intelligent temperature display shows real-time device temperature, while RGB lighting adds a customizable aesthetic. A dedicated lights-off mode disables illumination for distraction-free gaming or sleep. Compatible with most modern smartphones featuring flat backs or magnetic cases, it draws power via USB-C for plug-and-play operation. Ideal for extended gaming sessions, video recording, or heavy multitasking where thermal throttling reduces performance.
