Mobile gaming has evolved significantly, and the GameSir X3 Pro is a great way to improve your gaming experience with its innovative cooling solution and customisable design.

The X3 Pro has premium construction and ingenious design choices. The expandable mechanism feels robust, smoothly accommodating various phone sizes through its swivelling USB-C connector. The included carrying case is a nice touch – well-padded and sturdy enough to protect the controller during transport.
What sets this controller apart is its modular approach. The detachable grips, swappable joystick caps, and customisable buttons allow lots of personalisation. While I found the default ergonomic grips comfortable enough to keep attached, having the option to remove them is a brilliant option for those with smaller hands.

One important consideration when using the X3 Pro is phone case compatibility. During testing with the iPhone 16, I had to remove my case so the controller would fit properly. While some ultra-thin cases might work, most standard protective cases will need to be removed before connecting your phone to the controller. This isn't a significant drawback, but it's something to remember if you frequently switch between gaming and regular phone use.

The X3 Pro's built-in cooling system is great for phones with fast processors that can achieve high frame rates but soon drop off performance due to thermal build-up. This system uses advanced Peltier technology to deliver efficient heat dissipation with a maximum cooling power of 12W. This means your smartphone will stay cool even during prolonged gaming sessions, ensuring uninterrupted gameplay. The downside is that the fan must be plugged into power to work. I used a power bank so that I could stay relatively mobile.

The Hall Effect analogue sticks deliver precise 360-degree control, and anti-friction rings ensure smooth movement. The micro switches provide satisfying tactile feedback and excellent button responsiveness. The built-in 6-axis gyroscope adds another dimension to compatible games, though its usefulness varies by title.
Dual rumble motors provide convincing haptic feedback, enhancing immersion in supported games. The GameSir app allows you to fine-tune various aspects, including stick sensitivity and vibration intensity, though I found the default settings perfectly serviceable.
The controller works seamlessly with both Android devices and recent iPhone models. At 322.2g, it's lightweight enough for extended gaming sessions without causing fatigue. The package includes everything needed to get started.
The GameSir X3 Pro is a premium mobile gaming controller that balances features with functionality. Its cooling system effectively addresses the common issue of phone overheating, while extensive customisation options cater to different gaming preferences. For serious mobile gamers seeking a class-leading controller with active cooling, the X3 Pro is a solid choice. Once you get used to gaming with a controller, it’s hard to go back to playing without one.
