The cooling system works with two separate airflow channels. One channel directs air straight onto the processor to pull heat away during intense sessions, while the second channel draws cooler air in from the rear and expels it through a vent on the back panel. OnePlus China president Li Jie explains that this split‑path design tackles the “hot‑hand” issue that many gaming phones suffer from, where the chassis becomes uncomfortable after long play.
To improve heat removal, the phones incorporate tower‑style steel fins along the lower edge, a design borrowed from desktop graphics cards and CPU coolers. The fins give the tiny onboard fan a larger surface area, allowing it to move warm air more efficiently and keep the device cooler under sustained loads.
OnePlus also redesigned the intake and exhaust placement for landscape gaming. The intake sits away from the user’s fingers, and the exhaust vents upward, sending hot air away from the hands. This layout helps maintain comfort when the phone is held horizontally for extended periods.
Software support adds intelligent fan control that reads temperature in real time and adjusts fan speed on the fly. The result is quieter operation during casual use and stronger cooling bursts when a game pushes the hardware.
With this thermal solution, OnePlus says the Ace 7 series will deliver smoother frame rates and longer play sessions without the throttling that can ruin a gaming experience. The October 29 launch will bring these benefits to Chinese consumers, and the company hints that the same cooling technology may appear in future flagship devices. Early benchmarks suggest the cooling could lift sustained gaming performance by around 15 percent. A successful Chinese launch may lead to a global rollout later this year. The company also notes that the cooling system is designed to stay quiet during everyday use.
