Fans running to much on 2025 asus rog G16

Issues & Assistance
1

Long-time Linux user here, but first time running Arch. I finally decided to escape Windows and noticed CachyOS had solid ASUS support, including the ASUS-for-Linux kernel. Installation went smoothly, and I was able to install the ROG Control Center without any extra hassle — honestly, I’m loving it so far.

That said, I’ve run into one issue. Even in Balanced mode, my fans are noticeably louder than they ever were on Windows, and this is happening even when the system is basically idle. I’m not running anything heavy, yet the fans seem to be spinning constantly.

I wanted to ask if I might be missing something obvious — maybe a sensor package, thermal service, or power management component that needs to be installed or configured? I just want to make sure I’m not overlooking something and potentially stressing the hardware unnecessarily.

Any guidance would be appreciated. Thanks in advance!

You can try the following:

asusctl profile -P Balanced   # or Silent
asusctl fan-curve --help      # to see options and set curves

Monitor temps and speeds
In terminal:

sensors
asusctl fan -f

Power management extras (optional but helpful)
CachyOS is tuned for performance, so idle power might be slightly higher than ultra-optimized setups.
Install/enable TLP if not already (common on laptops):

sudo pacman -S tlp
sudo systemctl enable --now tlp

It helps with CPU scaling and can indirectly quiet fans by reducing heat.

thank you for the reply i went through these steps and im not seeing anything out of the ordinary but yet the fans still seem to be running a little to much any other suggestions and TLP is installed
