Appearance Design
The appearance design of RedMagic Cooler 4 Pro is in line with RedMagic’s consistent cyberpunk style. The shell adopts a black-gray translucent design, and it is made into a turbine-shaped shape that echoes the “cooling fan”. The bottom is made of aluminum alloy, and a horizontal stripe texture is added to add texture to the entire product.
The design of the hollow transparent shell has another advantage, that is, it will not block the RGB lighting effect. The transparent design and the cooperation of the lighting even played some complementary roles.
Cooling Performance – APP Support
The cooling performance of RedMagic Cooler 4 Pro is its core selling point. It adopts Redmagic Ice 4.0 semiconductor cooling technology, and customizes a piece of the industry’s largest TEC semiconductor cooling sheet, with an area of 40*40mm. Its working power has also reached 27W, which can efficiently and continuously maintain low temperature and better absorb the heat from the back of the phone.
The Cooler 4 Pro dropped the temperature of the back clip from 25°C to below 10°C in just 10 seconds. By 30 seconds, the lowest temperature on the surface had dropped to 2.2°C, and it dropped below 0°C within 3 minutes. After testing for 20 minutes, it has been maintained at around -1°C.
Such cooling efficiency is really amazing. However, this test was conducted when I adjusted the speed of the cooling fan to the maximum in the APP, and the purpose was also to test the most extreme cooling performance of Cooler 4 Pro.
In addition to manually adjusting the cooling effect of the fan through the APP. RedMagic Cooler 4 Pro has added an AI intelligent temperature control function. With the battery temperature of the mobile phone read by the APP, the radiator will automatically adjust its own working power to prevent the mobile phone from being too cold or overheating. However, this feature currently only supports Android devices.
In addition to semiconductor cooling fins and cooling fans, RedMagic Cooler 4 Pro also innovatively designed aluminum alloy turbo radiators and suspension air ducts, which increased heat transfer efficiency by 33%. At the same time, high-efficiency and high-heat silica gel is used to improve thermal conductivity.
Cooling Testing
After I played the “Honor of King” game on the phone for an hour, I used the RedMagic Cooler 4 Pro to cool down when the temperature reached 42.3°C in the upper right corner of the back of the phone and 36.5°C in the center. I used an infrared imager to monitor the temperature of the back of the phone and recorded the temperature change every 10 minutes.
RedMagic Cooler 4 Pro reduced the temperature on the back of the phone by 11.8°C and 8.1°C in one hour, the effect is very obvious. And during the whole process, I didn’t feel any obvious lag or frame drop on the phone, and the game experience was very smooth.
This shows that RedMagic Cooler 4 Pro can not only effectively reduce the temperature of the mobile phone, but also ensure the stable performance of the mobile phone, allowing players to enjoy a better gaming experience. Of course, this test was conducted when I adjusted the cooling fan speed to the maximum in the APP. If you want to save power or reduce noise, you can also adjust the fan speed or turn on the AI smart temperature control function through the APP.
Noise Control
The noise control of RedMagic Cooler 4 Pro is also commendable. It adopts the design of bass fan and suspension air duct, which can efficiently dissipate heat while maintaining bass operation. The noise is only 33dB, which is smaller than normal speech. In this way, it will not affect the sound effect of the game, nor will it disturb the people around.
In order to test its noise level, I measured it with a professional instrument and recorded the noise change every 10 minutes. The noise of Cooler 4 Pro basically stays within the range of 33~34.5dB within an hour, with very little variation. This shows that its noise control is very stable, and it will not increase the noise due to long-term use.
Such a noise level is very low for a radiator, even negligible. If you want a quieter environment, you can also adjust the speed of the fan through the APP or turn on the AI smart temperature control function, so that the radiator can automatically adjust the power according to the temperature of the mobile phone, thereby reducing noise.
Compatibility of RedMagic Cooler 4 Pro
Another highlight of RedMagic Cooler 4 Pro is its very strong compatibility. Not only can it be adapted to RedMagic series mobile phones, but also can be adapted to other brands of mobile phones. It adopts a magnetic installation method – there is magnetism on the back of the phone or a magnet sticker is attached to it, and it can be easily adsorbed on the phone without falling or shaking.
To test its compatibility, I’ve used it to cool down phones from different brands and models – including the iPhone 14 Pro, OnePlus 10 Pro, OnePlus Ace 2, and more. The test results show that RedMagic Cooler 4 Pro can be perfectly adsorbed on these phones, and can effectively reduce their heat generation and improve their game performance.
This shows that RedMagic Cooler 4 Pro is not only a professional game cooler, but also a general mobile phone cooler. No matter what brand and model of mobile phone you use, you can enjoy the cooling effect and gaming experience it brings.
Conclusion
RedMagic Cooler 4 Pro is a professional gaming cooler. It has the advantages of strong refrigeration performance, wide compatibility, and low noise control. It adopts a magnetic installation method, and with the complimentary magnetic sheet, it can be easily adsorbed on different brands and models of mobile phones.
It also has an exclusive APP that allows you to adjust the fan speed, turn on AI smart temperature control, check the battery temperature and other functions through your mobile phone, allowing you to more easily control the status of the radiator.
