Nubia’s REDMAGIC line of smartphones are meant for gaming. But the company has also branched out into PC and mobile accessories, and the REDMAGIC VC Cooler 5 Pro is a gadget that snaps onto the back of a wide range of phones (not just those made by Nubia) to provide extra cooling power.

It does that thanks to a liquid-cooled VC radiator and a spinning fan. The smartphone accessory will be available starting April 15 for $59 in North America, or €59/£49 in the EU and UK, 999 MXN in Mexico, or $88 in Singapore.

The VC Cooler 5 Pro features a magnetic design, allowing it to snap into place on the iPhone 12 or later or some other phones that support MagSafe-like accessories.

You can also pay an extra $5 for a bundle that includes a clip-on attachment that should expand the number of supported devices. Android users also get extra control over the fan’s performance thanks to an Android-only mobile app with a “REDMAGIC AI Thermal Control” feature.

The cooler itself measures 66 x 59 x 28mm and weighs 100 grams, and features a 7-blade, 5500 RPM fan and a thermoelectric cooler.

While this isn’t the first smartphone cooler to hit the streets, the company says the addition of liquid cooling improves performance by 50%. The new cooler is said to be able to lower a smartphone’s temperature by as much as 35 degrees Celsius to temperatures as low as -12 degrees Celsius (10 degrees Fahrenheit).

REDMAGIC says it can also drop a phone’s temperature from 28 degrees Celsius to 0 in just 30 seconds.

While I’m not sure how much demand there is for smartphone cooling accessories like the VC Cooler 5 Pro, I can say that there are times when my smartphone has gotten hot to the touch while recording 4K video… and then ended up stopping or corrupting the video due to overheating. I sure wouldn’t have minded having a cooler at that point… but sticking a spinning fan near my smartphone’s microphone probably wouldn’t have been the best idea if the goal is to record reliable audio and video.

That said, I can easily imagine overheating phones causing similar problems for gamers. And spending $59 on a cooler is probably a cheaper solution than buying a new phone.

  1. I would think the primary advantage to a chiller is speed. If I understand the limitations of say Snapdragon processors, performance cores can only run at maximum speed for perhaps 15-30 seconds before they get too hot and slow down. The more heat the phone can dissipate, the longer the processor can remain in it’s max-speed zone. So, any app running more than 15 sec, like a game, would appear more performant.

    1. Snapdragon chipsets, are “less hot” than they are “battery hogs”… especially when we’re talking about the Performance Cores.

      So even if you “solved” the heat issue, you now have the battery issue. And this Fan is already bulky. Having an external battery is just an even bigger and more bulk. I don’t think this is the solution.

      Besides what’s it all for? Just a bit more performance on your portable device which you probably can’t take advantage of ? And you’re not even getting comfort or ergonomics out of it, like the screen is tiny.

      For a tablet, it just naturally has a larger battery, and a much larger surface area to dissipate that heat. And it’s more ergonomic. It’s not pocketable, but neither is the above contraption both are portable. May as well get an iPad Mini or Pro, or AYN Odin2, or Valve SteamDeck, or GPD Win-Max-3.

  2. Very niche market for these phone coolers: vtubers who use iPhones for facial tracking. I’ve known a few who had complained about their phones overheating before.

  3. Update: the manufacturer explains that this is powered by a Zero Point Module, which is how it can achieve its impressive power in such a small form factor, and outperform the battery of the phone itself in a smaller volume!

    Hoppy Easter!

  4. I work outdoors and my phone can get quite hot just sitting in my pocket. This could be a good way to cool it off while out in the sun.

    1. It may not be the most fashionable thing to do in urban society, but I think most people would give you a pass if you attached your phone to a belt one way or another instead, while actually working outside.
      I know I wouldn’t want to carry two devices in my pockets, not to mention it doesn’t work if your phone is in a case.
