Understand the reading your Mac reports.
The thermal display is a system condition, which is different from a sensor temperature.
What GlimmerStatsBar (mac stats bar) shows
GlimmerStatsBar (mac stats bar) displays the thermal condition reported by macOS as Normal, Warm, Hot or Critical. Choose a word or a dot in the menu bar, or open the live card to read the current condition.
Thermal condition and temperature are different
GlimmerStatsBar (mac stats bar) offers both a macOS thermal-condition overview and supported temperatures in degrees through an optional sensor companion. The two readings answer different questions about your Mac.
Check support for your Mac
The optional sensor companion reads supported temperatures and fan speeds. Availability depends on your Mac and the sensors it exposes. Compare the iStat Menus comparison with GlimmerStatsBar (mac stats bar), iStatistica Pro comparison with GlimmerStatsBar (mac stats bar) and Stats comparison with GlimmerStatsBar for these differences. GlimmerStatsBar has no fan controls.
Keep the condition in context
A thermal reading is one piece of information about the current system. It does not identify a faulty component or measure the room temperature. If you are concerned about your hardware, use the Mac's support and diagnostic options rather than relying on one label.

Questions you might have
Does GlimmerStatsBar show CPU temperature in degrees?
Yes, on supported hardware with the optional sensor companion. Available temperature sensors and fan readings vary by Mac. Thermals, sensors and GPU details is shown separately.
Can it change fan speeds or cooling settings?
No. GlimmerStatsBar displays readings and does not change fan speeds, power settings or cooling behaviour.
