๐จ Alerts โ
Alerts notify you when important conditions are met (e.g., high temperatures, stalled fans). Both the Qt desktop application and the browser UI support desktop notifications.
Click the Alerts button to open the Alerts Overview page:
What you can monitor โ
- Temperature thresholds (above/below)
- Fan/pump speed thresholds (above/below) and stall detection
- Specific device channels or groups
How to create an alert โ
- Open the Alerts Overview and click Create Alert.
- Choose a sensor or channel to monitor.
- Set the condition (above/below), threshold, and optional duration (e.g., sustained for 10s).
- Save. The alert will trigger when conditions are met.
TIP
Pair alerts with Dashboards to verify trends leading up to a trigger.


Desktop Notifications โ
CoolerControl supports desktop notifications so you are alerted even when the application is not in focus.
Qt Application โ
The native Qt desktop application integrates with your OS notification system. Alerts are delivered as system notifications through your desktop environment (e.g., KDE Plasma, GNOME).
In-Browser Notifications โ
When accessing the UI in a web browser, you will be prompted to grant notification permission. Once granted, the browser will deliver background notifications for triggered alerts.
Self-signed certificates and background notifications
Background notifications require a secure context. When using the default self-signed certificate, browsers treat the origin as insecure and background notifications are not supported. To enable background notifications in the browser, use a trusted certificate โ see SSL/TLS for configuration options.
