    You can use ksysguard, if you don't want anything fancy.
    File > New Worksheet > Rows 1 Columns 2
    Sensor browser > ACPI > Thermal Zone > THRM > Temperature > Drag and drop > Signal plotter
    or depending on hardware
    Sensor browser > Hardware Sensors > k8temp-pci-003c > Temperature > Drag and drop > Signal plotter
    For fan depending on hardware
    Sensor browser > ACPI > Fan > FN00 > State > Drag and drop >Signal plotter

    As for the safe temperature limit you have to consult processor manufacturers thermal data sheet, found on their web site. Google for example "amd sempron thermal data sheet".

    In my laptop processor runs typically at ~60 C, but for heavy load temperature is ~90 C. Above that it cannot be forced to run at maximum frequency, but cpu slows to about 1/2 speed.
