日本ASUS ROG Zephyrus G14 GA402 (2023) review – vapor chamber cooling combined with metal build and high performance
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

The CPU in this laptop can sustain high frequencies and power limits in any kind of load. This is a great achievement for a 14-incher. Still, in “Turbo” mode, the CPU temperature is 95°C which isn’t that good. You can lower it by applying the “Performance” present at the expense of a bit lower clock.

|---|---|---|
| ASUS ROG Zephyrus G14 GA402 (2023) Turbo mode | 2565 MHz @ 77°C @ 101W | 2565 MHz @ 82°C @ 104W |
| ASUS ROG Zephyrus G14 GA402 (2023) Performance mode | 2364 MHz @ 78°C @ 86W | 2325 MHz @ 83°C @ 86W |
| Acer Nitro 16 (AN16-51) | 2520 MHz @ 67°C @ 92W | 2520 MHz @ 67°C @ 91W |
| MSI Thin GF63 (12V) | 1735 MHz @ 69°C @ 45W | 1729 MHz @ 70°C @ 45W |
The GPU can maintain a 104W TGP and 2565 MHz core frequency after 30 minutes of gaming. If the fans are too noisy for you, you can again select the “Performance” mode which offers less noise but the GPU frequency is 2325 MHz.
In the table below, you can see the performance difference between the “Turbo” and “Performance” scenarios. The latter looks like the way to go since it offers almost the same results alongside lower fan noise.

Comfort during full load
The fans are pretty loud in “Turbo” mode during heavy CPU stress and their noise levels are acceptable in “Performance”. When the CPU is under 100% load, the middle of the keyboard feels hot but it’s still okay for usage. In this scenario, the WASD section and the two palm rest areas are cool enough for work or gaming.
Let’s check the fans’ speed in idle. In “Silent” mode, they are completely turned off if the CPU temperature doesn’t exceed 60°C. In “Performance”, we got 2100-2400RPM and 2500-2700RPM in “Turbo”.
“Silent” Idle
“Performance” Idle
“Turbo” IdleWhen the CPU is stressed at 100%, the fan RPM is 3200-3400RPM, 3800-4200RPM in “Performance”, and 5200-5700RPM in “Turbo”.
You can also set different fan modes for DC and AC usage.
Battery
Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. This laptop’s 76Wh battery lasts for 20 hours of Web browsing or 10 hours of video playback!
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
you are lieing. 10 hours battery life watching videos
We do the battery test at 120 nits brightness (rather low) and only VLC running, so if you are using the laptop with other programs and at higher brightness, you should expect less battery life.
