With the arrival of hot summer, the high temperature in summer is not only for people, but also a lot of challenges for mobile phones. Many users encounter the overheating of the mobile phone body during the process of playing games or even daily use. Every summer, the mobile phone becomes hot after playing a few games, not to mention whether this will have an impact on the life of the mobile phone. The problem of being stuck just because of fever has made many players and friends feel distressed.
then the question is coming. what should I do if my mobile phone is hot? Do you throw the refrigerator? In fact, the solution is very simple. It is enough to buy a cooling back clip! For most mobile phones, limited by the structure of the fuselage, most of their own cooling systems have limited capacity, so it is difficult to play much role once they encounter high temperature weather. In contrast, plug-in devices with active heat dissipation, such as heat dissipation back clips, have a good effect, keeping the mobile phone in a reasonable temperature range all the time, and making the game experience stable in hot summer days.
of course, just as smart phones have different prices, so do small heat-dissipating back clips. Different prices determine that there will be some differences in the design, materials and actual performance of products. As for whether the most expensive is the best, are all cheap parallel imports? And is semiconductor, which everyone is concerned about, an IQ tax on the heat dissipation of mobile phones? These problems need to be measured before we know.
Therefore, in this review, we selected eight kinds of heat-dissipating back clips that are popular at present, most of which come from different brands and different price ranges. We will tell you what kind of products are most worth recommending through actual tests.
first of all, let me introduce to you the eight radiators tested this time, namely: Benks W7 refrigeration wireless charger (268 yuan), Black Shark Frozen Refrigeration and Cooling Backclip 2 magnetic suction version (249 yuan), Black Shark Frozen Radiator PRO(179 yuan), Red Devil Dual-core Cooling Backclip (179 yuan), YOUMAKER semiconductor mobile phone cooling radiator (79 yuan) and Staercke semiconductor intelligent temperature control mobile phone radiator.
these eight participating radiators basically cover multiple price segments from low to high. in view of this, we also divided eight products with different price points into four echelons: entry, mainstream, high-end and flagship. This cross-evaluation will evaluate the measured performance, heat dissipation technology, interface compatibility, design details and feel experience, so that everyone can get a certain understanding of the category of mobile phone radiator and give some purchase suggestions.
in this cross-evaluation test, we selected the most concerned mobile game scenes for testing. The testing method is to use two mainstream models, iPhone 12 and Xiaomi 11, with 8 radiators respectively, and run the Genshin Impact game for 3 minutes (the original God's game screen is set to high-quality +6-frame mode), and then record the back shell temperature of the mobile phone at this time.
from the overall data obtained from this test, although the data of heat dissipation effect obtained from the test is not linearly related to the price of the mobile phone radiator itself, it can be clearly found that the mobile phone radiator can effectively improve the game experience of the smart phone, and has obvious cooling effect, and the higher the price, the better the overall heat dissipation performance of the mobile phone radiator will be.
after seeing the overall data performance, let's start the echelon analysis. At the entry level, Kewo air-cooled mobile phone radiator and Yise mobile phone radiator, two entry-level mobile phone radiators with the price of 39 yuan, are selected. Compared with other echelon products, these two products have a bigger gap compared with higher-priced products in terms of packaging and workmanship.
in terms of heat dissipation effect, after 3 minutes of game testing, the back cover temperature of iPhone 12 and Xiaomi 11 decreased by .7 and 5.5 respectively under the condition of using Kewo air-cooled mobile phone radiator for auxiliary heat dissipation, and the game frame rate reached 55.4 frames and 36.8 frames respectively; Using billion-color mobile phone radiator can reduce the temperature of the back cover of iPhone 12 and Xiaomi 11 by 1.7 and 6.5 respectively, and the game frame rate is 56.1 and 35.4 frames respectively.
from the data performance, it can be seen that when used with the iPhone 12, the heat dissipation effect of Yise mobile phone radiator is relatively better, but the improvement is not obvious compared with Kewo air-cooled mobile phone radiator. Both products can bring certain temperature improvement when used with Xiaomi 11, which can greatly improve the stability of game frame rate.
Below 1 yuan and above 5 yuan are the mainstream price ranges for most players to buy mobile phone radiators. In this price range, we chose YOUMAKER semiconductor mobile phone refrigeration radiator (79 yuan) and Staercke semiconductor intelligent temperature control mobile phone radiator (79 yuan) for testing. From the perspective of product packaging and workmanship, there is no obvious gap between these two mobile phone radiators and entry-level products, and the overall texture is relatively rough.
after a 3-minute game test, the back cover temperature of iPhone 12 and Xiaomi 11 decreased by 2.5 and 1.3, and the game frame rate reached 57.4 and 38.1 respectively under the condition of using YOUMAKER semiconductor mobile phone cooling radiator for auxiliary heat dissipation. Using Staercke semiconductor intelligent temperature-controlled mobile phone radiator can reduce the back cover temperature of iPhone 12 and Xiaomi 11 by 4.2 and 5.4 respectively, and the game frame rate is 58.6 and 41 respectively.
through the data, we can find that although the texture of these two mobile phone radiators is similar to that of entry-level products, their heat dissipation effect is greatly improved compared with entry-level products. Especially in the process of using with iPhone 12, the radiator of Staercke semiconductor intelligent temperature control mobile phone has excellent heat dissipation effect, which is second only to the heat dissipation performance of high-end products.
This improvement in heat dissipation effect is probably due to the fact that both products use semiconductor materials as heat dissipation medium, so it can be considered that it is worthwhile to spend more money in 4 yuan to buy more expensive mainstream radiators than to buy entry-level products, and at the same time, semiconductor heat dissipation materials can also play their due role, instead of the so-called "IQ tax" products.
The players of the high-end product echelon mainly come from the game mobile phone manufacturers. Both the Black Shark Frozen Radiator PRO and the Red Devil Dual-core Heat Dissipation Back Clip adopt the back clip design method. Both the Black Shark Frozen Radiator PRO and the Red Devil Dual-core Heat-dissipating back clip are designed with two-way stretching clips, and the contact part with the mobile phone bezel is made of silicone, which can not only stabilize the mobile phone but also protect the bezel. In terms of detail design, both of them are satisfactory.
in terms of cooling performance, both the Black Shark Iced Radiator PRO and the Red Devil Dual-core Heat Dissipation Backclip adopt the cooling design of fan plus semiconductor cooling chip, but the fan size of the Black Shark Iced Radiator PRO is larger, while the Red Devil Dual-core Heat Dissipation Backclip has two fans.
after a 3-minute game test, the average back shell temperature of iPhone 12 and Xiaomi 11 supported by Black Shark Iced Radiator PRO decreased by 9.8 and 8.4 respectively, the core temperature decreased by 8 and 5 respectively, and the game frame rate reached 59.4fps and 43.3fps, which increased by 19.1fps and 14.3fps；. The average temperature of the iPhone 12 and Xiaomi 11 supported by the Red Devils dual-core cooling back clip decreased by 6.9 and 8.8 respectively, while the core temperature decreased by 4 and 8 respectively, and the game frame rate reached 57.6fps and 44.8fps, which increased by 17.3fps and 14.9fps.
High-end group test results
In terms of frame rate performance, the Black Shark Iced Radiator PRO and the Red Devil Dual-core Heat Dissipation Backclip have both won and lost. On the iPhone 12, the Black Shark Iced Radiator PRO reached 59.4fps, exceeding the Red Devil Dual-core Heat Dissipation Backclip. In Xiaomi 11, the performance of the Black Shark Frozen Radiator PRO is slightly inferior to that of the Red Devils dual-core cooling back clip. The performance of temperature can basically be seen from the change of frame rate. For example, on the iPhone 12, the PRO frame rate of the Black Shark Iced Radiator is better, and the corresponding changes in the rear shell temperature and the core temperature are also greater. On Xiaomi 11, the PRO frame rate performance of the Black Shark Iced Radiator is slightly lower than that of the Red Devils Dual-core Heat Dissipation Backclip, and the corresponding changes in the back shell temperature and core temperature are also smaller than those of the Red Devils Dual-core Heat Dissipation Backclip.
On the whole, both the actual performance and the actual experience are very close, and there are winners and losers in the comparison test between iPhone 12 and Xiaomi 11, but this is an isolated case after all, and it has not opened the absolute gap, so this data itself does not explain too many problems, so if it is only from the data level, the two are more evenly divided.
As the flagship products of the eight products, Benks W7 Refrigeration Wireless Charging or Black Shark Frozen Refrigeration Cooling Back Clip 2 Magnetic Absorbing Edition, these two cooling back clips reflect their high quality in all aspects, and can effectively complete the basic cooling work. However, for the flagship products, the cooling is just the beginning, and the more important thing is how to further improve the actual use experience of users.
first of all, let's look at the heat dissipation effect. Because Benks W7 refrigeration wireless charger can't be fixed on Xiaomi 11 in a relatively reliable way, this radiator has not been tested in combination with Xiaomi 11.
according to the test data, after 3 minutes of Genshin Impact, the average temperature of the back shell of the iPhone 12 with Benks W7 refrigeration and wireless charging decreased by 3.3, the core temperature decreased by 2, and the frame rate reached 55fps, which increased by 14.7fps；. The average temperature of the back shell of the iPhone 12 and Xiaomi 11 supported by the black shark's frozen cooling back clip 2 with magnetic suction is 6 and 6 lower than that of the bare metal back clip without cooling back clip at room temperature, and the core temperature is 1 and 3 lower. The average frame rate of the game in 3 minutes is 58.1fps and 42.4fps, respectively, which is 17.8fps and 12.5fps higher.
As the flagship echelon products, both of them choose the active cooling mode of built-in cooling fan and semiconductor cooling sheet. By comparison, it is obvious that the actual effect of the magnetic suction version of Black Shark's frozen cooling back clip 2 is better, which can greatly improve the frame rate of mobile phones and reduce the temperature.
from the design point of view, both of them are designed by magnetic attraction, which can be fixed on the back of the mobile phone without clamping, which is quite convenient. It should be noted that at present, the magnetic attraction design of the two models is optimized for the iPhone 12 model, and the Benks W7 refrigeration wireless charger cannot be applied to the models without magnets without accessories; The same is true for the magnetic version of Black Shark Iced Refrigeration and Cooling Backclip 2, but the magnetic version of Black Shark Iced Refrigeration and Cooling Backclip 2 provides official magnetic attachment accessories for users to choose from.
it's worth mentioning that Benks W7 refrigeration wireless charger is not only a heat dissipation back clip, but also a 15W wireless charging board. You can choose "charging", "cooling" or both by adjusting the mode, so the actual functionality is more abundant. The interfaces at both ends of the magnetic suction version of Black Shark Iced Refrigeration and Cooling Backclip 2 are type-C, and the data cable is pluggable, so the magnetic suction version of Black Shark Iced Refrigeration and Cooling Backclip 2 can sometimes serve as a mobile phone bracket, which Benks W7 refrigeration wireless charger does not have. In other respects, the two are similar in size, and moderate volume and weight will not have much operational impact when holding the mobile phone horizontally.
from the comparison between the two, it can be affirmed that both Benks W7 refrigeration wireless charger and Black Shark's frozen refrigeration cooling back clip 2 magnetic suction version have obvious cooling effect, and also play a role in stabilizing the game frame rate. However, if we only consider from the perspective of refrigeration, it is obvious that the magnetic version of Black Shark's frozen cooling back clip 2 is better. If you just want to buy a cooling back clip, then the cheaper black shark's frozen cooling back clip 2 is more suitable. However, Benks W7 Refrigeration Wireless Charge also has the function of wireless charging. If you also need this, then Benks W7 Refrigeration Wireless Charge is your responsibility.
constrained by the current development of chip technology, mobile phone processors will inevitably bring high calorific value while achieving high performance. Coupled with the hot summer weather, it is common for mobile phones to overheat during games. In this context, it is undoubtedly a practical and effective solution to match a mobile phone radiator with a smart phone.
from the overall test and analysis results, it can be found that in most cases, the more expensive mobile phone radiator will generally have better heat dissipation effect; However, there are some exceptions. For example, Benks W7 refrigeration wireless charger takes into account the charging function, so its heat dissipation effect is not as good as that of other mobile phone radiators at the same level.
for most ordinary players, it is a very good choice to buy a mainstream mobile phone semiconductor radiator whose price is from 5 yuan to 1 yuan. Semiconductor radiators of this grade, such as YOUMAKER semiconductor mobile phone cooling radiator and Staercke semiconductor intelligent temperature control mobile phone radiator, can effectively reduce the body temperature of the mobile phone during the game, improve the frame rate performance of the game, and bring a more carefree game experience.
for relatively hard-core gamers, a higher-end mobile phone radiator is obviously a better choice. For example, the black shark ice-sealed cooling back clip 2 magnetic version is very suitable for users who use iPhone 12 series models to avoid the influence of the cooling back clip on the grip; The Red Devils dual-core cooling back clip is a mobile phone radiator that is very suitable for Android flagship model. Its double fan design dissipates the heat on its semiconductor heat sink faster, and the butterfly wing design can expand the contact area of the heat sink to bring better heat dissipation effect.

For users of iPhone 12 series models who need to play while charging, Benks W7 refrigeration wireless charger is a product that can meet their needs, but its cooling effect is not significant; The cooling effect of Kewo air-cooled mobile phone radiator is not obvious. For users who want to buy entry-level radiator products,
