I verified the specifications of the game-only mode of ASUS gaming smartphone 'ROG Phone 5 Ultimate' & examined the cooling effect of the dedicated cooler

ASUS 'ROG Phone' latest & top model ' ROG Phone 5 Ultimate ' comes with a dedicated external cooler '

AeroActive Cooler 5 '. I actually verified the meaning of attaching an external cooler to a smartphone, the ability of 'X mode +' released when 'Aero Active Cooler 5' is installed, and the cooling effect.

◆ Game-only mode 'X mode +'
The ROG Phone series had a special mode called 'X mode ' that optimizes game hardware processing to improve game data processing performance. In this ROG Phone 5 series, if you install the dedicated external cooler 'Aero Active Cooler 5', the enhanced version of X mode 'X mode +' will be released, and you can further improve the performance. AeroActive Cooler 5 can be purchased separately for 5980 yen including tax.

This time, we will perform benchmark measurement of ROG Phone 5 Ultimate with 'X mode +' in mind. 'X mode +' can be turned on and off from the quick setting panel when AeroActive Cooler 5 is installed. If AeroActive Cooler 5 is not installed, it will be in 'X mode'.

So, let's run the standard benchmark application 'GeekBench 5'.

First, let's do a CPU benchmark in 'X mode' without installing Aero Active Cooler 5. The result is a single-core score of '1121' and a multi-core score of '3612'. Detailed results can be checked from the URL.

Next, install Aero Active Cooler 5 and run the CPU benchmark in 'X mode +'. The result was a single-core score of '1122' and a multi-core score of '3632'. Regarding the CPU, the impression that the difference between X mode and X mode + is almost an error.

Now let's run the GPU. First, in 'X mode', the API measures the OpenCL score. The result was '4693'.

Next, the OpenCL score of 'X mode +' was '4709'.

In addition, let's measure the GPU score of Vulkan API. The score of 'X mode' is '4207'.

On the other hand, the Vulkan score of 'X mode +' was '5826'. So, X mode + makes a big difference if the API is Vulkan, but in other states it feels like an error.

◆ About the cooler performance of Aero Active Cooler 5
If you keep launching high-load apps such as games that make heavy use of 3D graphics, the smartphone itself tends to get hotter and hotter. AeroActive Cooler 5 can lower the CPU temperature of ASUS ROG 5 by up to 10 degrees and the surface temperature of the main body by up to 15 degrees by the fan mounted in the center.

That's why I will actually install it and use it. AeroActive Cooler 5 automatically rotates the fan according to the heat generated when it is connected to the terminal body. The strength of the wind is such that the tissue paper is lightly sucked in as shown below.

That's why we will measure the temperature when the fan is driven using

'FLIR ONE Pro ' that can be used as an external thermo camera for smartphones. ASUS ROG 5 Ultimate got hot in the endurance test mode 'Wild Life Stress Test' of the benchmark application '3DMark' mentioned above, so this time I am measuring with this. This time, when AeroActive Cooler 5 is not installed, it is operated in X mode, and when AeroActive Cooler 5 is not installed, it is operated in X mode +, so it is considered that a measurement error has occurred, but X mode / X mode + is used. When it was turned off, the main body did not get so hot and it was difficult to see the difference, so this time I put in X mode / X mode +.

First of all, the state where Aero Active Cooler 5 is not installed. The display side is 48.0 degrees.

The back side is 40.9 degrees. In addition, in order to match the measurement position with when AeroActive Cooler 5 is installed, the part slightly off the center is measured.

Then, after a sufficient amount of time has passed, the Aero Active Cooler 5 is attached and measurement is performed. The timing is also set to 5 minutes from the start of the 'Wild Life Stress Test'. The display side is 43.6 degrees.

The back side is 29.9 degrees. After repeating the procedure multiple times, the results varied, but all seemed to have a solid cooling effect.

After this, we plan to review the camera of 'ROG Phone 5 Ultimate' and the game that is the biggest feature in

order with the dedicated controller 'ROG Kunai 3 Gamepad'.
