PC gamers know about summer. When you’re in the middle of an intense in-game battle, the last thing you want is for your computer to start working because your CPU or GPU has gotten too hot. That’s why gamers and other extreme users rely on products like CPU coolers and liquid cooling systems. You probably haven’t been worried about your smartphone’s thermals while playing candy Crush on your iPhone. Still, Razer released a new product, phone cooler chroma, on Tuesday to make sure your smartphone doesn’t overheat the next time you use it for gaming.

Of course, mobile gaming has moved on from the likes of candy Crush And Angry Birds. Razer (and a few other vendors) have been trying to make mobile gaming a serious thing for a while. The company’s efforts are mostly focused on controllers like the Razer Kishi, which connect to your smartphone. Razor’s too finger sleeve for mobile gaming,


The phone cooler Chroma released on Tuesday has a different purpose. Compatible with both iPhone and Android phones (It supports “most smartphones”, Razer’s product page claim), the product is meant to help keep your phone cool while it’s moving those frames.

Interestingly, the fan takes advantage of Apple’s MagSafe, allowing you to magnetically attach the cooler. This is convenient, but it also means that the cooler won’t sit directly on top of the phone’s SoC.

If you don’t have a MagSafe-compatible phone, you can opt for a version with a universal clamp.

We don’t know how adjustable the cooler is, but Razer says it works with phones 2.64-3.46 inches (67-88 mm) wide.

A cooling plate sits on the back cover and is topped by an electronic tile that uses Peltier cooling, also known as thermoelectric cooling, to transfer heat. The next layer is a heatsink beneath a seven-blade fan that spins 6,400 revolutions per minute, adjustable via Bluetooth. Razer says the cooler can stay at 30 dB.

Above the fan is a cover with air vents, and—of course—RGB lighting. Do lights help keep your phone cool? off course not. But without it it almost wouldn’t be a Razer product. The gaming brand has kept RGB on its N95 mask as well, so the chroma lighting comes as no surprise here.

RGB sounds like a razor requirement.

The cover has 12 RGB LEDs, and each can be set to its own color and effect.

You’ll need a USB-C cable to power the Chroma Phone Cooler. The cooler comes with a 4.9-foot (1.5 m) USB-C to USB-C cable, but it seems like it could be cumbersome when gaming on the go, as a mobile gamer is inclined to do.

Requires power over USB-C.

Razer made no claims about how cool the product will keep your phone’s components. Unlike CPU coolers, this cooler does not come into direct contact with the processor, and has no exhaust vents to function as some laptop fan coolers do. So the heat transfer from the actual SOC may be limited. Hardcore mobile gamers can find out $60. for myself,
