Nubia Launches Magnetic Smartphone Cooler with Sub-Zero Performance

Nubia has officially launched the Ice Cream Cooler, a magnetic accessory designed to significantly lower smartphone temperatures during intensive use. The device, which began retail sales in China on September 11, 2026, utilizes advanced thermoelectric technology to manage heat more effectively than traditional passive coolers. According to GN technics/mobile (en-US), the product is built to handle sustained loads from gaming, fast charging, and outdoor exposure.

The accessory features a distinctive white, speckled design that mimics cookie-and-cream ice cream, though its primary function is technical. It attaches to the back of compatible devices using neodymium magnets and includes clips for non-magnetic phones. While the aesthetic is playful, the engineering behind it is serious, capable of reducing device temperatures by up to 60 degrees Celsius under heavy load.

Advanced Thermoelectric Cooling Technology

The core of the device is a 36 by 36 millimeter thermoelectric plate, which actively pumps heat away from the processor rather than just spreading it out. This system works in tandem with a cold-forged aluminum heatsink and copper thermal components to maximize efficiency. The result is a cooling capacity of up to 25 watts, allowing the surface of the phone to drop as low as -18 degrees Celsius in controlled tests.

To dissipate the extracted heat, a seven-blade fan spins at speeds up to 6,000 RPM. The airflow is directed away from the user’s hands to prevent discomfort. An integrated NTC chip regulates the process automatically, ensuring the system does not overcool or drain excessive power. This active cooling approach is particularly useful for users who find their phones throttling performance during long gaming sessions or video streaming.

User Controls and Operating Modes

Users can switch between four distinct modes via physical buttons on the device: Silent, High Power, Overclocking, and Temperature Control. The Silent mode reduces fan speed to a minimum of 33 decibels, making it suitable for quiet environments. In contrast, the High Power and Overclocking modes maximize cooling output to support sustained high-performance tasks. The Temperature Control mode allows for precise manual adjustment of the target temperature.

The cooler also includes RGB lighting with various visual effects, adding a customizable aesthetic element. Weighing 90 grams and measuring 25 millimeters in thickness, the device is compact enough for mobile use without adding excessive bulk. A standard 1/4-inch screw mount is included, allowing the cooler to be attached to tripods or streaming rigs for stationary setups.

Pricing and Compatibility Trade-offs

The accessory is compatible with both Android and iOS devices, as well as tablets, provided they have a flat back surface for the magnetic or clip attachment. The launch price in China was 99 yuan, roughly 14 USD, though the regular retail price is set at 159 yuan, approximately 22 USD. International buyers on marketplaces like AliExpress may face higher costs due to import fees and shipping.

The main trade-off for users is the added weight and the need for an external power source, as the thermoelectric plate and fan consume battery power if not plugged in. Additionally, the magnetic attachment requires either a built-in magnetic module or the use of the provided clips, which may not fit all phone cases seamlessly. Despite these minor hurdles, the device offers a robust solution for those struggling with thermal throttling.
