fancontrol as a Linux alternative to NZXT CAM
Updated
Our verdict
fancontrol is a solid replacement for the fan management and monitoring aspects of NZXT CAM, but it is not a direct 1:1 swap. It handles PWM fan curves and sensor display effectively, making it ideal for users who prioritize system stability and low resource usage over RGB aesthetics. However, if you rely heavily on NZXT CAM for controlling RGB lighting on NZXT devices, fancontrol will not help you. It is best suited for users who want to decouple fan control from proprietary software and are comfortable using standard Linux sensor tools.

What works the same
- Real-time display of hardware temperatures and fan speeds
- Ability to create custom fan speed curves based on temperature thresholds
- Support for multiple saved configurations to switch between profiles
- Lightweight design that runs as a background utility without heavy GUI overhead
What is different
- No RGB lighting control for NZXT or other devices
- Does not use NZXT-specific hardware protocols, relying instead on standard kernel sensors
- Requires manual udev rule configuration for proper hardware access
- Lacks the integrated dashboard aesthetic of NZXT CAM, focusing purely on functional control
Opening your NZXT CAM files
fancontrol does not support importing or exporting configuration files from NZXT CAM. The two applications use completely different underlying systems for hardware communication and profile storage. You will need to manually recreate your fan curves and temperature thresholds in fancontrol based on the settings you used in NZXT CAM.
Switching from NZXT CAM to fancontrol, step by step
- Install fancontrol from your distribution repository or Flathub
- Install lm-sensors and run sensors-detect to ensure all hardware sensors are visible
- Add the required udev rule to your system as specified in the fancontrol GitHub documentation
- Launch fancontrol and verify that your fans and temperature sensors are detected
- Create a new configuration and map your desired fan speeds to temperature ranges
- Test the configuration under load to ensure the curves behave as expected
Key features of fancontrol
- Automatically adjusts fan speed based on sensor readings
- Supports PWM and voltage-controlled fans
- Real-time display of temperature and fan speeds
- Customizable control curves and thresholds
- Saves multiple configurations
- Integrates with lm-sensors for hardware monitoring
- Configurable update intervals and logging
How to install fancontrol on Linux
flatpak install flathub io.github.wiiznokes.fan-controlFrequently asked questions
Can fancontrol control my NZXT RGB fans?
No, fancontrol only manages fan speed via PWM or voltage. It does not handle RGB lighting. You will need a separate tool for lighting if that is a requirement.
Why do I need to add a udev rule?
Linux requires specific permissions for user-space applications to directly control hardware like fans. The udev rule grants fancontrol the necessary access to the fan control files in the sysfs filesystem.
Is fancontrol better for performance than NZXT CAM?
Generally, yes. fancontrol is a lightweight utility designed specifically for fan control, whereas NZXT CAM is a heavier application that also handles RGB and other features. fancontrol will typically use fewer system resources.
