That clever design is inextricably linked to performance, because that little fan is directly responsible for keeping the Snapdragon 8s Gen 4 chipset cool under pressure. And crikey, does it work. Firing up Grid Legends, the phone held a stable 30FPS at high settings without the chassis getting remotely toasty. Even pushing PUBG at the highest possible settings, it hummed along at a smooth 45FPS without threatening to sear our fingertips. You can, of course, lower the graphics to get even higher frame rates, but our mission was to push the GPU to its limits, and the Storm Engine barely broke a sweat. For a streamer or pro gamer, that stability is gold. Compared to similarly priced gaming phones we’ve tested, the Oppo doesn’t really break any new records in terms of benchmark scores or gaming performance; it’s only the heat management aspect of it that brings value. By that I mean, you will only see the benefits of this fan once you’ve passed the 40 to 50-minute mark of gaming and are well into the thermal throttling zone, where the competition, like Poco F7 and iQOO Neo 10, might drop in performance by a few FPS compared to Oppo K13 Turbo Pro.
Again, this active cooling works in tandem with the equally massive 7000mm² vapour cooling chamber, and that’s a good deal for anyone looking to spend all their waking hours gaming. The phone also packs some neat software and hardware tricks. Bypass Charging lets you power the phone directly to the motherboard during gaming, saving the battery from heat and strain. ColorOS 15's Game Assistant includes a 'Game Camera' feature that lets you record the last 30 seconds of gameplay, so you never miss a clutch moment.
A quick word of warning: you can definitely hear the fan when it’s at full tilt. It’s not a jet engine, but if you’re playing something like PUBG or CODM where audio cues are the difference between chicken dinner and digital death, you’ll want to pop on a pair of headphones.
