Introduction

Mobile gaming has become increasingly demanding, pushing smartphones to their thermal limits. Overheating can lead to performance throttling, battery drain, and even damage to your device. This review takes an in-depth look at the DL05 Funcooler mobile phone cooler, a semiconductor heatsink with a built-in fan, promising significant temperature reduction for phones ranging from 65mm to 85mm in width.

Features

The DL05 boasts several key features designed to combat overheating. The prominent water-cooled radiator system is its core strength, promising a substantial temperature drop (10-30°C claimed). The inclusion of a powerful, 7500 RPM fan ensures efficient heat dissipation. A digital temperature display keeps you informed about your phone’s temperature, and the RGB LED lighting adds a touch of gamer flair. The 1.5m long Type-C cable provides ample reach, and the universal design ensures compatibility with a broad range of smartphones and tablets.

Performance

I tested the DL05 with several demanding mobile games over extended periods. While the advertised 10-30°C reduction wasn’t consistently achieved under all conditions, the cooler noticeably reduced the surface temperature of my phone, particularly during intensive gaming sessions. The fan is quite powerful, but it’s not overly noisy; it’s audible, but not distracting. The temperature display is accurate, providing useful real-time feedback. The clip mechanism is secure and easy to use, fitting my phone snugly without feeling too tight or leaving any marks. I found that extended use (more than an hour) did lead to some warming of the cooler itself, but the overall temperature difference remained beneficial compared to playing without it.

Pros & Cons

• Pros: Effective cooling, easy to use, accurate temperature display, good build quality, RGB lighting.
• Cons: Cooling performance varies based on game intensity and ambient temperature; The cooler itself does warm up after prolonged use; No warranty is a negative.

Final Verdict

The DL05 Funcooler is a solid mobile phone cooler that delivers on its promise of reducing phone temperature during gameplay. While it doesn’t always reach the maximum advertised cooling, it makes a significant difference in preventing overheating. The ease of use and additional features like the temperature display and RGB lighting add to the overall experience. The lack of warranty is a concern, but if you’re looking for a reliable way to keep your phone cool during gaming sessions, the DL05 is a worthwhile investment.
