Ive recently got my laptop opened up by a repair shop due to the fan not spinning but after they fixed it ive noticed that the fan is being louder than usual is there a way i can adjust the fan speed?

I was gaming on my laptop and noticed that the fan speeds are quite low and the laptop is super hot.

I ran auto-cpufreq --monitor, and given the temperature, the RPM seems really low to me.

I tried fancontrol, but running sudo pwmconfig returns:

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

So it doesn’t work.

Any Asus Zenbook users who have managed to control their fan speed on Linux?

My exact model is ASUS Zenbook 14 UX3405MA.

finding a decent fan control app for asus laptops is rough. the official software is bloated, and most 3rd party tools are buggy, laggy, or just abandoned.

i got tired of dealing with that, so i built the tool i always wanted. i took the best ideas from what’s out there, threw away the broken parts, and rebuilt everything from scratch to make it stable and smooth.

that’s how Zenith Fan Utility came to be, a no-nonsense fan controller that actually works in 2025:

• lag-free fan curve editor – add, remove, and drag points instantly.

• modern ui – fully dpi-aware, sharp text, no tiny or blurry controls.

• stable + lightweight – no memory leaks, no random crashes.

• smart tray control – live stats on hover, one-click toggle for the window.

• advanced features made simple – hysteresis, refresh rate config, all functional.

• free & open source – no ads, no telemetry, no junk.

note: works only with asus system control interface v3.1.40.0 or older (newer versions block manual fan control). the github readme has a quick guide to check/downgrade if needed.

if you’ve been frustrated with the options out there, give this one a shot. i built it to be the last fan utility you’ll need.
