CM-RGB-MONITOR(1)

💖 CM-RGB-MONITOR(1) 💖

okay bestie so this is a page from the User Commands manual, and it's literally about making your cooler glow in real time. no cap, this is the one. 🦋

✨ NAME ✨

cm-rgb-monitor — drive the CM RGB / Wraith Prism LEDs from live CPU load, temperature and fan speed

---

🌈 SYNOPSIS 🌈

cm-rgb-monitor [OPTIONS]

---

💅 DESCRIPTION 💅

So cm-rgb-monitor just... runs. forever. continuously. it's giving main character energy that never exits. ✨ It samples your CPU load (and optionally temperature and fan speed if you've got lm-sensors/psutil hooked up) and updates the cooler's LEDs to reflect those readings in real time.

The way that it works: the ring shows CPU load as a rotating arc 🔥, and the logo/fan LEDs can optionally show temperature or CPU frequency as a color gradient, or strobe in sync with fan speed (that's the mirage effect, and yes it's iconic).

---

🎀 OPTIONS 🎀

• --bg-color HEX — the background LED color, bestie. default: #00FFFF.
• --cpu-color HEX — the color of the CPU-load LEDs. default: #FFA500.
• --brightness 1-5 — LED brightness, and it gets clamped to 1–5 (so don't try to be extra, it won't let you). default: 4.
• --interval SECONDS — how often it updates, 0.01–60. default: 0.2.
• --verbose — prints the CPU load and sensor readout to stdout, so you can actually see what's going on 👀.
• --show-temp — shows the selected temperature sensor's reading on the cooler's fan LED.
• --temp-source CHIP/FEATURE — the temperature source, given as <chip>/<feature> (like k10temp/Tdie, which is the default). use --list-temp-sources to see what's actually available on the current system, periodt.
• --temp-low DEGREES — the temperature considered "low" for the color gradient. default: 50.
• --temp-high DEGREES — the temperature considered "high" for the color gradient. default: 80.
• --temp-low-color HEX — the color representing low temperature. default: #00FFFF.
• --temp-high-color HEX — the color representing high temperature. default: #FFA500.
• --show-cpu-frequency — shows the current CPU frequency on the logo LED as a color gradient. lowkey obsessed. 💜
• --freq-low-color HEX — the color representing low CPU frequency. default: #00FFFF.
• --freq-high-color HEX — the color representing high CPU frequency. default: #FFA500.
• --smoothing 0-1 — smoothing applied to the measured values so the LED color changes are less jumpy 🧚; 0 disables smoothing, and values near 1 average heavily over time. default: 0.8.
• --mirage — enables the mirage effect: strobes the fan LED at a frequency derived from the current fan speed. ✨
• --mirage-fan CHIP/INDEX — the fan speed source for the mirage effect, given as <chip>/<index>. default: nct6797/1.
• --mirage-factors R,G,B — the fan speed-to-mirage-frequency factor(s), as one shared value or a comma-separated red,green,blue triplet. experiment with different values to change the strobe pattern (that's literally the point, go off). default: 7.0,7.0,7.0.
• --list-temp-sources — prints the available <chip>/<feature> temperature sources detected via lm-sensors, and then exits.
• --help — shows a summary of options and exits.

---

🌸 EXAMPLES 🌸

show CPU load on the ring and temperature on the fan LED:

cm-rgb-monitor --show-temp

list the available temperature sensors so you can pick a --temp-source:

cm-rgb-monitor --list-temp-sources

enable the mirage fan-speed strobe effect with custom factors:

cm-rgb-monitor --mirage --mirage-factors 5.0,7.0,9.0

okay that's the whole page, you're welcome 🫶 this was cm_rgb version 0.4.0, dated 2026, and it's still CM-RGB-MONITOR(1) if you needed to cite your sources. go make your cooler slay 🌈💅
