The Black Shark Fun Cooler 3 Pro BR31 promises powerful cooling for smartphones, particularly during demanding gaming sessions. I’ve spent several weeks putting this device through its paces, testing its capabilities in various scenarios. This review will delve into its performance, features, and overall usability.

The Black Shark Fun Cooler 3 Pro BR31 boasts several key features designed to effectively dissipate heat. The most noticeable is the high-speed, seven-blade fan. Beyond that, the separated cooling structure, with its independent cooling zone and cleverly placed circuit board, is a standout element. The in-app control is a welcome addition, offering granular control over fan speed and RGB lighting. The compact and lightweight design makes it easy to carry around. Finally, its compatibility with a wide range of smartphones is a huge plus.

My testing involved several hours of intensive mobile gaming, including graphically demanding titles. The Fun Cooler 3 Pro BR31 consistently kept my phone’s temperature significantly lower than without it. The difference was particularly noticeable during extended play sessions. The fan is relatively quiet, even at its highest speed. The in-app control was intuitive and responsive, allowing for easy adjustments on the fly. While the cooling is impressive, I did notice a slight performance drop in one particularly demanding game. It wasn’t significant, and I attribute this more to the game’s resource demands than the cooler itself.

I also tested the cooler’s performance with various phone orientations and game styles. It consistently performed well, demonstrating its versatility. The attachment mechanism is secure and easy to use. The RGB lighting, while aesthetically pleasing, is customizable enough to not be distracting. Overall, the performance consistently lived up to expectations.

Pros

• Effective cooling performance
• Quiet operation
• Intuitive in-app control
• Compact and portable design
• Wide smartphone compatibility
• Customizable RGB Lighting

Cons

• Minor performance dip experienced in a single, graphically intense game (likely game-specific)
• Price point might be a factor for some consumers.

The Black Shark Fun Cooler 3 Pro BR31 is a highly effective mobile cooling solution that delivers on its promises. Its powerful cooling, coupled with the convenient in-app control and compact design, makes it a worthwhile investment for serious mobile gamers. While there is a small caveat regarding potential performance issues in extreme scenarios, these issues were minimal and largely game-dependent. I highly recommend the Black Shark Fun Cooler 3 Pro BR31 to anyone looking to enhance their mobile gaming experience and prevent overheating.
