i7tt is a nice CPU temperature monitor. It draws each core in line chart in Braille and groups all cores in a bar chart for overview, which uses different colors to indicate the temperature ranges.


There is only one command-line option for average period. It uses coretemp drivers sysfs interface to get the data.
