iQOO 15 Ultra: Unveiling the Smartphone with the Industry's Largest Active Cooling Fan

Anticipation is building for the imminent launch of the iQOO 15 Ultra, a device rumored to redefine smartphone thermal management. Central to its innovative design is what's alleged to be the biggest active cooling fan ever integrated into a smartphone. Recent leaks, courtesy of the prolific Digital Chat Station on Weibo, provide a fascinating glimpse into this groundbreaking cooling architecture.

A shared schematic reveals the strategic placement of the cooling fan's components. The air intake is cleverly positioned at the base of the camera island, ensuring efficient airflow. The warmed air is then expelled through an outlet located on the side frame of the device. This active cooling solution is expected to feature a fan with impressive dimensions: a 17mm diameter and 4mm thickness, reinforcing claims of its unprecedented size within the mobile industry.

Beyond the impressive fan, the iQOO 15 Ultra also incorporates a substantial vapor chamber. This advanced thermal component works in conjunction with the active fan to create a formidable cooling system. The synergy between these elements is designed to guarantee smooth, prolonged gaming sessions, effectively preventing performance throttling even under intense loads.

The iQOO 15 Ultra isn't just about cooling; it's packed with other rumored high-end specifications. Enthusiasts can expect a massive 7,800 mAh battery, the same high-quality display featured in the iQOO 15, and the cutting-edge Snapdragon 8 Elite Gen 5 SoC. This combination of top-tier hardware, especially its advanced cooling, positions the iQOO 15 Ultra to potentially break benchmark records upon its release, delivering unparalleled performance for demanding users and mobile gamers.
