An Asus laptop fan roars with Armoury Crate installed
How do I fix Asus laptop fan running loudly with Armoury Crate installed?

Short answer
Armoury Crate takes over fan control from the firmware. If it is set to Turbo or Performance, or if its own services get stuck after an update, it holds the fans high no matter how idle the machine is. Its background services are also fairly heavy in themselves. The quickest thing to try first: put the laptop into silent mode — Press Fn+F5 to cycle through the modes, or open Armoury Crate, go to the Home or Operating Mode tab and choose Silent (Windows mode on some models). This is the intended switch and it usually quietens the fan straight away. Most people are done in about 15 minutes.

Sounds like this
- •The fan spins hard while you are only browsing
- •It ramps up and down every few seconds
- •The noise started after installing or updating Armoury Crate

Build a manual fan curve
In Armoury Crate go to Device, then GPU Power Saving or the Fan Profile area, choose Manual, and drag the lower points of the curve down so the fans stay near zero until about 60 degrees. Save the profile.

Turn off per-app performance profiles
Armoury Crate has Scenario Profiles that switch to Turbo when certain apps open, and Chrome is often on that list by default. Open Scenario Profiles and disable it, or remove the apps that trigger Turbo.

Repair a stuck installation
If the fans ignore every setting, the service has hung. Open Task Manager, Services tab, and restart ArmouryCrateControlInterface and ASUSOptimization. If that does not help, reinstall using the official Armoury Crate Uninstall Tool from Asus support, restart, then install the current version from the Asus download page for your exact model.

Update the BIOS and MyASUS
Asus regularly ships fan curve fixes in BIOS updates. On the Asus support page for your model, download the latest BIOS and install it with WinFlash while on mains power. Do not interrupt it.

Rule out real heat
Open Task Manager and watch CPU usage for a minute. If something is genuinely sitting at 40 percent or more, the fan is right to be loud, and the fix is that process, not Armoury Crate. Vacuum the vents too, since a dusty laptop runs hot and loud whatever the software says.
If none of that worked
If you would rather not run Armoury Crate at all, use Asus's official uninstall tool and then MyASUS, which is much lighter and still gives you the fan modes. Firmware takes fan control back once Armoury Crate is fully removed.
