Must-buy original cooler for REDMAGIC phones? Don’t rush to spend money first, I tested several mainstream flagship coolers in 2026, the advantages and disadvantages of these two REDMAGIC models, whether they are worth buying or not, after reading you can directly make a decision, no need to struggle anymore about premium pricing or IQ tax.

01 In the core parameters of REDMAGIC coolers, only these points truly affect the experience
The coolers currently mainly promoted by REDMAGIC are the 8 Pro and 8 Air, first cut out all the useless parameters, directly talk about the differences ordinary people can perceive.

REDMAGIC 8 Pro
36W power + 1640mm² cooling plate, idle can reach -25℃, can drop up to 38.4℃ in 2 minutes, upper and lower air outlet does not blow hands, with microcrystal temperature sensing window (will change from black to blue when becoming cold), noise 36dB, weight 116.7g, first sale starts from 229 yuan.

REDMAGIC 8 Air
18W power, lowest -20℃ cooling, 30dB silent, weight only 65g, three-level modes, magnetic attachment and clip dual-use, first sale 129 yuan.

Simply speaking, the 8 Pro is a performance version prepared for heavy users, the 8 Air is an entry-level version focusing on lightness, both are magnetic attachment designs, non-magnetic models can be used after attaching a magnetic sheet, Android, Apple, tablets, and Switch can all be matched.
In actual testing, the 8 Pro running Diablo Mode for 30 minutes of 《Honkai: Star Rail》, the highest temperature on the back of the phone dropped from 42.7℃ to 29.7℃, the average frame rate increased from 113.3 frames to 118.9 frames, it indeed can solve the frequency reduction problem under high load, belonging to a configuration that can truly improve gaming stability.

Moreover, its adaptation with REDMAGIC phones is the best, paired with REDMAGIC 11 Pro+ turning on Diablo Mode, 35 minutes of 《Golden Spatula Battle》 average frame rate can reach 139.89 frames, around 15 frames higher than attaching at the center position of the phone, belonging to the extra gain of ecosystem collaboration.

Its shortcomings are also very clear.
First, it must be paired with a PD charger above 30W to run at full power, using phone reverse charging can only reach level 3 fan speed at most, performance directly cut in half. Secondly, the size is 25% larger than ordinary coolers, the 116g weight hanging on the phone for a long time indeed makes hands tired, and if using a thick case the magnetic attachment will become unstable, the case needs to be removed or a magnetic sheet attached.

02 Compared with Black Shark and Flydigi models in the same price range, is REDMAGIC worth buying
I pulled the flagship models of the three giants in 2026 for comparison, all are mainstream models in the 200-300 yuan price range, the dimensions are all points actually useful in real use, no need to look at fake parameters.

Model Power Full-load Noise Grip Area Temperature (Android platform 30-minute Star Rail) Core Advantage Core Disadvantage
 REDMAGIC Cryo Cooler 8 Pro 36W 36dB 31℃ Fastest cooling speed, strongest power, temperature visualization Air outlet temperature as high as 45.2℃, relatively large size
Black Shark 6 Pro 35W Within 40dB 29.1℃ Equipped with 0.7-inch smart display, customizable screen display Performance release not as stable as REDMAGIC, some batches have performance differences
Flydigi B9X - ≤35dB 26.9℃ Good power consumption control, low hot air temperature, lighter weight Low power, weak suppression ability under high load

2026 flagship cooler horizontal comparison (data from third-party actual testing)

The conclusion is very clear, if only looking at cooling performance, REDMAGIC 8 Pro is currently T0 level, the suppression ability under full power condition is indeed stronger than the other two models, it can completely suppress the heat of phones and tablets, no need to buy more expensive water cooling, belonging to performance redundancy.

But its air outlet temperature is also the highest, although it is upper and lower air outlet not directly blowing hands, when using in summer there will still be obvious heat feeling around it, those caring about grip temperature can choose Flydigi. Black Shark’s advantage is having a display screen, with higher playability, but performance release is not as stable as REDMAGIC.
As for REDMAGIC’s controller, currently the official main promotion is the phone’s built-in dual touch shoulder buttons, supporting custom macros and four-finger linkage, delay and response speed are both in the first tier, no need to additionally buy an external controller, unless you play emulators or stream PC games, otherwise the built-in shoulder buttons are completely enough.

03 Which people are worth buying it, and which people should directly save this money
Directly give the clear conclusion, no need to struggle anymore.
If you are a REDMAGIC phone user, especially using the 11 Pro series turning on Diablo Mode to play high-load games, directly buy the 8 Pro, the frame rate improvement from ecosystem collaboration cannot be matched by third-party cooling, belonging to a rigid demand bonus item.
If you are a heavy mobile game player, playing high-load games like 《Genshin Impact》 and 《Star Rail》 for more than 2 hours every day, or doing mobile game live streaming, the suppression ability of the 8 Pro is completely enough, the frame stabilization effect is better than other models in the same price range, also worth buying.
If you are using an iPhone or an old flagship whose cooling itself is poor, often getting hot to the point of frequency reduction and lag when gaming in summer, the 8 Pro can also solve the problem, actual testing on iPhone 16 Pro Max using it for high-load gaming for 40 minutes, the body remained cool the whole time, frame rate basically had no fluctuation.

These types of people directly do not need to buy.
Only playing games like 《Honor of Kings》 and 《Golden Spatula》 with not high load, and phone temperature normally never exceeding 40℃, the 8 Pro for you is completely performance redundancy, buying a hundred-yuan-level cooler is enough, or just choose the 8 Air.
Those caring about weight, usually liking to play games with a bare phone or using a thick case, also do not buy the 8 Pro, 116g hanging on the phone for a long time makes hands sore, thick cases also affect magnetic attachment effect, not as good as choosing the lighter Flydigi or clip-on models.
Those who do not have a PD charger above 30W in hand, and also do not want to spend extra money to buy one, also do not buy the 8 Pro, if unable to run at full power then there is no difference from hundred-yuan coolers, purely wasting money.
Finally saying one sentence, this set of REDMAGIC peripherals is not some belief recharge, nor is it useless, the core depends on whether your usage scenario can match its performance, do not spend extra wasted money for “ceiling” parameters that you cannot use.
