Laptop gets hot while compiling, the fan is no longer distinguishable from a hairdryer? This waybar module lets you to tune down the maximum allowed frequency. It relies on the setuid bit to be able to write to /sys/devices/system/cpu/cpufreq.

Example waybar config:

    "custom/cpufreq": {
        "exec": "/path/to/plugin/cpufreq/cpufreq get",
        "interval": "once",
        "exec-on-event": true,
        "return-type": "json",
        "format": "{icon} {percentage}%",
        "format-icons": ["🐢", "🐇", "🐎"],
        "tooltip-format": "CPU-Throttle: {percentage}%",
        "smooth-scrolling-threshold": 1.5,
        "on-scroll-down": "exec /path/to/plugin/cpufreq/cpufreq down",
        "on-scroll-up": "exec /path/to/plugin/cpufreq/cpufreq up"
    },
