The iQOO 15 Ultra is launching soon and it’s rumored to boast the biggest active cooling fan ever put into a smartphone. Today the prolific leaker who goes by Digital Chat Station on Weibo has shared the image you can see below, showing a schematic of the device and the fan.
The air intake for the fan is positioned at the bottom of the camera island, while the air outlet is positioned on the side, in the frame. The fan itself is alleged to measure 17mm in diameter and 4mm thick, and it’s once again claimed to be the biggest in the industry.

In addition to the fan, there’s also a big vapor chamber inside the iQOO 15 Ultra, which works with the fan to ensure smooth prolonged gaming sessions with no throttling. The iQOO 15 Ultra is rumored to sport a 7,800 mAh battery, the same screen as the iQOO 15, and the Snapdragon 8 Elite Gen 5 SoC.
The iQOO 15 Ultra is going to break benchmark records when it comes out, thanks to its cooling system.
