This accessory attachment is for the GameSir X5 series of mobile gaming controllers, for the X5 Lite and X5s. The FX5 Lite is the wired-only version of the FX5 phone cooler, which also offers RGB lighting and wireless operation. It's an interesting device that slots into the back of your X5 Lite or X5s controller and features a 25mm x 25mm cooling plate and a built-in fan that operates in Silent, Cooling, and Overclock modes. All modes are relatively quiet white noise, but certainly not silent. The FX5 Lite is powered using a USB-A to USB-C cable included in the box with your own provided wall-charger or powerbank if on the go. In theory, it draws the heat away from the backplate of your smartphone; however, the thickness of your case likely impacts the level of performance. I don't own any temperature measurement tools, so I can only say yes, I believe it helped to cool my iPhone; however, to what level, I'm not entirely sure. It's a bit of a premium product at $45 at the time of this review, and while yes, the build quality of the devices seems excellent, as most users would expect from GameSir, I'm not entirely sold on the value proposition. It adds bulk to the X5s I tested it with, along with a cable dangling, so it's not the most ergonomic option; however, if cooling performance is paramount to you, then this may be an accessory you must have. A recommended buy if you are a hardcore mobile gamer; otherwise, you may consider watching to see if it goes on sale in the future. Read more

This cooler fits perfectly on the X5 line of gamepads. In my case, I paired it with the X5s. When attached, it feels like it is part of the controller arm and rests tightly again the back of your device. It has a large heat sink and fan, that operates at 3 levels of speed. Even at the highest speed the fan is fairly quiet. I removed one start because the device requires a usb-c power source to run, very much limiting its portability. If your device gets hot when playing demanding games, you have an X5, and don't mind being wired to the wall, then this is for you. Read more

The FX5 Lite Phone Cooler is a good piece of gear if you're a serious mobile gamer. Designed specifically for the GameSir X5 controllers, it's highly effective and works exactly as advertised, with the three cooling modes doing a great job of keeping your device from overheating during intense sessions. Just a heads up, though: while the cooling is top-notch, you have to be mindful of a few things. It does add some extra bulk and requires an external power source, which might feel a little clunky. Also, the positioning is limited, and the clamps can potentially leave small marks on your phone or tablet if you’re not careful. All in all, it’s a powerful tool, but these are worth considering before you buy. Read more

I was expecting a simple fan and a heatsink, but no - this is an actual Peltier cooler - and it does a very good job. It's so good that in testing I could freeze water drops on the cooling pad in a warm room. Very efficient and very cold. Read more
