Summer is coming, can your phone still smoothly play games? The impact of high temperatures on the heating and sustained performance of phones is self-evident. If a chip platform with poor performance in power consumption and energy efficiency is used, it may be even more embarrassing in summer. For game users who have such troubles, directly attaching a heat dissipation back clip to the phone is undoubtedly the most direct and effective solution.

As a mobile phone manufacturer deeply involved in the gaming industry, Red Magic has recently launched a series of new coolers, including the one we are going to talk about today, the Original RedMagic Magnetic Cooler 4 Pro
, which is said to be the "strongest" product. This cooler has two versions, one is a back clip and the other is a magnetic suction type. The one we received this time is the magnetic suction type, which can be magnetically adsorbed on the MagSafe-supported iPhone 14 Pro, or it can be "transformed" into other phones by using the included magnetic suction sheet and transparent protective film.

The appearance design of the RedMagic Magnetic Cooler 4 Pro is very consistent with Red Magic's consistent cyberpunk style. The shell adopts a semi-transparent design in black and gray, and is made into a turbine shape that corresponds to the "cooling fan". The middle frame at the bottom is made of aluminum alloy material and added with horizontal texture, which adds texture to the entire product. The design of the hollow transparent shell also has another benefit, which is that it will not cover up the dazzling RGB flowing light effect on the phone body at all. After all, as a gaming equipment, the traditional skill of RGB lighting effects cannot be lost. The design of the transparent part even plays a complementary role with the light.

The cooling performance of the RedMagic Magnetic Cooler 4 Pro is its core selling point. It uses Red Magic's fourth-generation semiconductor cooling technology and customizes the industry's largest TEC semiconductor cooling sheet, which has an area of ​​40*40mm. The working power of this semiconductor also reaches 27W, which can efficiently and continuously maintain low temperature and better absorb the temperature on the back of the phone. The RedMagic Magnetic Cooler 4 Pro only took 10 seconds to reduce the temperature of the back clip from 25℃ to below 10℃. The speed of temperature decrease was even faster than that of the second hand of a clock. By the time it reached 30 seconds, the lowest surface temperature had already dropped to 2.2℃, and after 3 minutes, it continued to maintain at below 0℃. The cooling efficiency is indeed amazing, but this test was conducted when we set the cooling fan to the maximum in the APP, and the purpose was also to test the extreme cooling performance of this product. In addition to manually adjusting the cooling effect of the fan through the APP, the RedMagic Magnetic Cooler 4 Pro also adds an AI intelligent temperature control function. Together with the phone battery temperature read by the APP, the cooler will automatically adjust its working power to prevent the phone from running too cold or too hot. However, this function is currently only supported by the Android client, and iOS users cannot enjoy this humanized function for the time being.

Apart from semiconductor cooling chips and fan cooling, the RedMagic Magnetic Cooler 4 Pro also innovatively designs an aluminum alloy turbine radiator and a suspended air duct, which increases the heat dissipation efficiency by 33%. At the same time, it also uses high-efficiency and high-heat silicone gel to improve the thermal conductivity efficiency, reflecting the elaborate construction of Red Magic's heat sink products in these details.

We played "King of Glory" on the iPhone 14 Pro for an hour, and the temperature reached 42.3℃ in the upper right corner of the phone's back, and the center temperature was 36.5℃. We used the RedMagic Magnetic Cooler 4 Pro to cool down. We used an infrared imager to monitor the temperature on the back of the phone and recorded the temperature changes every 10 minutes. It can be seen that the RedMagic Magnetic Cooler 4 Pro reduced the back temperature of the iPhone 14 Pro by 11.8℃ and 8.1℃, respectively, within an hour, and the effect was very obvious. Moreover, during the entire process, we did not feel any significant stuttering or frame dropping of the phone, and the gaming experience was very smooth. This shows that the RedMagic Magnetic Cooler 4 Pro can not only effectively reduce the phone's heat generation but also ensure the phone's stable performance, allowing players to enjoy a better gaming experience. Of course, this test was conducted in the APP by turning the cooling fan to the highest level. If you want to save power or reduce noise, you can also adjust the fan speed or turn on the AI intelligent temperature control function through the APP.

Another highlight of the RedMagic Magnetic Cooler 4 Pro is its strong compatibility, which can not only adapt to the Red Magic series of phones but also adapt to other brands of phones, even flagship models like the iPhone 14 Pro. It uses a magnetic installation method, as long as there is a magnet or a magnet sticker attached to the back of the phone, it can be easily adsorbed on the phone without falling or shaking.

To test its compatibility, we used it to cool down phones of different brands and models, including the iPhone 14 Pro, OnePlus 10 Pro, and OnePlus Ace2. The test results showed that the RedMagic Magnetic Cooler 4 Pro can perfectly adsorb to these phones and effectively reduce their heat generation, improving their gaming performance. This shows that the RedMagic Magnetic Cooler 4 Pro is not only a professional game heat sink but also a universal mobile phone heat sink. No matter what brand or model of phone you use, you can enjoy its cooling effect and gaming experience.

The noise control of the RedMagic Magnetic Cooler 4 Pro is also worth praising. It adopts a low-frequency fan and suspended wind channel design, which can maintain low noise operation while efficiently dissipating heat. The noise is only 33dB, which is smaller than a normal speaking voice. This way, it will not affect the game's sound effects or disturb the people around you. In order to test its noise level, we measured it with a decibel meter and recorded the noise changes every 10 minutes. The noise level of the RedMagic Magnetic Cooler 4 Pro remained within the range of 33-34dB for one hour, with very small fluctuations. This indicates that its noise control is very stable and will not increase due to prolonged use. Such a noise level is very low for a cooler and can even be ignored. If you want a quieter environment, you can also adjust the fan speed or turn on the AI intelligent temperature control function through the APP, allowing the cooler to automatically adjust its power based on the phone's temperature and reduce noise.

The RedMagic Magnetic Cooler 4 Pro is a professional gaming cooler with strong cooling performance, wide compatibility, and low noise control, allowing you to enjoy a smoother, more comfortable, and more immersive gaming experience. It uses a magnetic suction installation method and comes with a magnetic suction sheet, which can be easily attached to different brands and models of phones. No matter what phone you use, you can use it to cool down. It also has an exclusive APP that allows you to adjust the fan speed, turn on AI intelligent temperature control, and view battery temperature, making it more convenient for you to control the cooler's status. If you are a gaming enthusiast, then the RedMagic Magnetic Cooler 4 Pro is definitely a must-have gadget for you.
