While accessory maker GameSir usually manufactures budget-friendly mobile controller accessories, the GameSir X3 Type-C is an entirely different beast, offering not only a customisable controller but impressive built-in cooling too.

Overheating is a problem faced by most mobile gamers during long gameplay sessions – even those with gaming phones sporting dedicated cooling systems – usually resulting in a hot spot on the rear of the smartphone, and a knock-on effect on performance and battery drain too.

The GameSir X3 Type-C looks to solve that problem by attaching a literal fan-powered cooling system to the back of your smartphone. The multi-part system, including a cold copper plate, a Peltier cooling module, heatsink and seven-blade fan helps keep your smartphone cool, reducing the temperature by up to an impressive 24 degrees Celcius in just a few minutes. 

The fans are lit by RGBs to add to the gamer look, and the position of the fan can be adjusted to better suit your smartphone if needed. The only downside? With no built-in battery, the fan needs constant USB-C power to operate, meaning you’ll have to use a power bank if you want to use it on your travels.

Of course, the X3 Type-C isn’t just a cooler – it’s also a mobile controller, and a pretty capable one at that. Connecting to your phone via its USB-C port, there’s 0 lag, and the controller plays nicely with all controller-ready games available on Android including cloud streaming apps from the likes of Nvidia and Xbox.

It’s impressively customisable too. The buttons are magnetic, allowing you to switch between Xbox- and Nintendo-style layouts, and there are two sets of thumbstick caps and D-Pads in the box to choose from too. That’s all stored in a nice hard shell carry case, keeping the controller and all accessories in one place.

It’s compatible with a range of smartphones too, as long as it offers USB-C connectivity and measures between 110-179mm.
