The first shot of esports mobile phones in 2022 will be launched by tomorrow's Redmi K50 esports edition, followed by the next day, the first machine of the year with an air-cooled active cooling system - the Red Devil 7 series; and the second (series), the Lenovo Savior Y90, will also be unveiled in the near future.
Below last week's popular science and experiment article on "VC vaporizers", a message asked a new question: "Do you want to know if the built-in fan is really better than the heat dissipation without the fan?"
But in view of the fact that the new air-cooled Snapdragon 8 Gen 1 model has not yet been released, in order to explain this problem, the only way to look at last year's models is to try to find the answer from the Snapdragon 888 Plus and Snapdragon 888 platforms.
▲ Red Devil 6 Pro
▲ Savior 2 Pro
In 2021, there are too many models equipped with Snapdragon 888 Plus and Snapdragon 888, and here can only be scattered to choose a few models to compare and illustrate, but there are only a few models with air-cooled heat dissipation, and in our WHYLAB model library, models equipped with active air-cooled cooling systems have Snapdragon 888's "Savior 2 Pro" and "Red Magic 6 Pro", as well as Snapdragon 888 Plus platform's "Red Magic 6S Pro".
▲ Red Devil 6S Pro
As a comparison of non-air-cooled cooling models, the OPPO Find X3 Pro, OnePlus 9 Pro, and Xiaomi 11 Ultra of the Snapdragon 888 platform were selected; while the Snapdragon 888 Plus platform selected the Xiaomi MIX 4, vivo X70 Pro+, honor Magic 3 Pro These three models are selected - the above models are listed in the order of release.
▌Snapdragon 888
To create suspense, we first show the heat of the non-air-cooled cooling models in our WHYLAB laboratory standard "five-hour endurance test" in the order of release, mainly looking at the maximum temperature recorded during the process:
OPPO Find X3 Pro
Released March 11
OnePlus 9 Pro
Released March 24
Xiaomi Mi 11 Ultra
Released March 29
The release time of the above three machines is very close, all released in March 2021, and the highest temperature on the front and back sides is higher than 40 °C, which is not cool to tell the truth.
Then look at the Red Devils 6 Pro with wind-cooled heat dissipation and the Savior 2 Pro:
Red Devil 6 Pro
Released March 4
Lenovo Savior 2 Pro
Released April 9
Compared with the above data, it is obvious that the wind-cooled Red Devil 6 Pro cooling effect is remarkable, the maximum temperature on the front is only 38.6 ° C, and the back is reduced to 36.8 ° C, and you can see the heat emitted by the heat map frame.
However, the highest temperature on the back of the same air-cooled Savior 2 Pro is 41.2 °C, which is no better than the 40.3 °C, 40.4 °C OnePlus 9 Pro and Xiaomi 11 Ultra?
In fact, no, first of all, we need to explain the Rescuer 2's (default) air cooling system startup strategy - unlike the Red Devil 6 Pro's strategy of automatically adjusting the fan according to the temperature of the fuselage, the Rescuer switches the air cooling system according to the scene, and by default, the fan will only be activated in the game scene - and the highest temperature recorded in our test is actually in the "video" project that does not turn on the fan, the recorded temperature is naturally half a pound with the ordinary mobile phone, if you look at the "game" project that automatically opens the air cooling mode, positive, The maximum temperature on the reverse side is actually only 38.9°C and 38.3°C, which is only slightly weaker than the Red Devil 6 Pro, which basically proves that the air cooling system is effective.
▌Snapdragon 888 Plus
Then look at the Snapdragon 888 Plus platform model in the second half of the year, first look at the Xiaomi MIX 4, vivo X70 Pro+, Honor Magic 3 Pro, these three non-air-cooled and heat dissipation models.
Xiaomi Mi MIX 4
Released August 10
vivo X70 Pro+
Released September 9
Honor Magic 3 Pro
Released September 12
To make a digression, compared with the Snapdragon 888 model in the first half of the year, the temperature control of the Snapdragon 888 Plus model in the second half of the year is generally better - the Snapdragon 888 Plus architecture and process have not improved, and there is no obvious improvement in performance, and the overall improvement of the temperature control level of the flagship model in the second half of the year may actually be forced by manufacturers to become a "dragon trainer".
Then look at the Red Devil 6S Pro with air cooling system:
Red Devil 6S Pro
Released September 6
The effect is still quite obvious, even compared with the Red Devil 6 Pro in the first half of the year, the mid-term upgrade of the Red Devil 6S Pro as a whole has a slight improvement.
Overall, the active air cooling system equipped with a cooling fan is indeed much better than the ordinary flagship at work; but still that sentence, every component inside the smart phone is the result of balance in all aspects - the air cooling system is good, but its working noise, as well as the weight and size of the fuselage, the impact is not negligible, otherwise they will not only be seen on some e-sports and game mobile phones today.
If you're interested in heat dissipation systems and materials, check back to an article by WHYLAB in March last year – "Why is it so hard to calm down your phone?"
And can the next release of the Red Devils 7 Series and the savior Y90 with dual fans go further? It won't be long before you know the answer.
