The GameSir X3 Pro has an integrated fan to keep your smartphone cool while playing games, but you need to be tethered to power to take advantage of it.

  • Fan requires external power

The past few years have seen giant strides in the quality of games on offer for smartphones. But as mobile gaming gets more demanding, our phones start to sweat.

A hot phone typically means the battery drains much faster, which isn't ideal for playing those higher quality games. Which is why I was intrigued by GameSir's X3 Pro controller, which aims to solve this problem with an integrated fan.

Compared to the other gaming controllers I’ve tested, the X3 Pro has some unique styling that won’t suit everybody, and there’s a significant catch with its main selling point, which in my mind undermines the whole product.
