Although the heat dissipation of smartphones is getting better and better, the back of the phone still heats up severely when playing games for a long time, which results in frame drops and lag. Many smartphone manufacturers will reduce the power of the processor chip to suppress heat generation, sacrificing performance to change the heat dissipation. This method can be effective, but without performance, the gaming experience is compromised. Can we solve the heat dissipation problem without affecting performance? The mobile phone radiator is a perfect assistant. Through physical heat dissipation, it quickly takes away the heat and cools down the phone, maintaining the best performance output at all times. Red Magic has launched a RedMagic Back Clip Cooler 4 Pro, which can quickly cool down to minus 7 degrees Celsius. After playing a game, the back of the phone is surprisingly cool.

The silver packaging box has a product rendering and model on the front and a mechanical and anime design style, giving a strong sense of technology. In addition to the radiator body, the package also includes a dual type-c data cable and an instruction manual. The RedMagic Back Clip Cooler 4 Pro adopts a small aircraft shape and a mechanical wind design, which is very cool. The shell material is plastic, and the pure silver color gives a metallic texture. The clamping range is 70-85mm, compatible with most smartphones on the market. My phone is 74.95mm wide, and the fit between the radiator and the back of the phone is very high, with almost no gaps, and the clamping is very stable.

The RedMagic Back Clip Cooler 4 Pro is equipped with the fourth generation Red Magic semiconductor refrigeration technology, which uses custom TEC semiconductors. The hot and cold are separated without affecting each other, effectively blocking heat feedback, improving cooling efficiency, and providing a continuous and stable cooling effect. The air outlet has a very large area and uses a top and bottom air outlet design so that hot air does not blow onto your fingers. It supports RGB lighting effects with colorful lights that create an immersive atmosphere. By long-pressing the control button on the body, you can switch the lighting mode, which is highly playable. Click the control button to switch gears, and there are four gears in total.

The highest output power is 27W, which is considered high power among coolers on the market. In an unloaded state, it can cool down to 32℃, and under load, it can cool down by 20℃, with a minimum of -7℃. In an environment with a temperature of 25℃, using the highest gear and playing a round of PUBG, the game screen was stable and smooth throughout the entire process without frame drops or stuttering. Afterward, touching the back of the phone, it was actually cool, and the cooling effect was very obvious. Although it is a high power device at 27W, the noise control is not bad, and even at the highest gear, it does not affect the gaming experience.

With a cool mech appearance, silver metal texture, personalized RGB lighting effects, full of e-sports style, and excellent heat dissipation performance, the phone can maintain stable output at all times, providing the ultimate e-sports experience. Overall, the RedMagic Back Clip Cooler 4 Pro is very good in appearance and functional experience. In addition to the back clip edition, there is also a magnetic suction edition with a smaller size for those who prefer it.
