The temp[[:digit:]] things are confusing. Can the output of sensors be more human readable?$ sensorsacpitz-virtual-0Adapter: Virtual devicetemp1:        +59.0C  (crit = +127.0C)temp2:        +60.0C  (crit = +100.0C)thinkpad-isa-0000Adapter: ISA adapterfan1:        2990 RPMtemp1:        +59.0C  temp2:        +53.0C  temp3:        +41.0C  temp4:        +76.0C  temp5:        +36.0C  temp6:            N/A  temp7:        +33.0C  temp8:            N/A  temp9:        +43.0C  temp10:       +51.0C  temp11:       +49.0C  temp12:           N/A  temp13:           N/A  temp14:           N/A  temp15:           N/A  temp16:           N/A Now it is like the following. Do they indicate my laptop is healthy? Do I have to worry about that? The reported temperatures are when I am opening 100 tabs in chrome browser now. They are achieved when I use a cooler and scale the cpu frequency to the lowest 0.8GHz. WIhtout a cooler, the highest temperature will be over 80 celcius. If further without cpu freq scaling, the highest can be 90 and 100 celcius.$ sensorsacpitz-virtual-0Adapter: Virtual deviceCPU_0:        +57.0C  (crit = +127.0C)CPU_1:        +56.0C  (crit = +100.0C)thinkpad-isa-0000Adapter: ISA adapterFan:                                                   2939 RPMCPU neighbourhood (also via ACPI THM0):                 +57.0C  Ultrabay:                                               +51.0C  Express card:                                           +38.0C  ATI graphics module:                                    +73.0C  Main battery (always around 50C):                     +36.0C  n/a (probably ultrabay battery):                            N/A  Main Battery (fits about the value reported by smapi):  +33.0C  n/a (probably ultrabay battery):                            N/A  Hard disc:                                              +40.0C  Intel graphics module:                                  +48.0C  Heatsink?:                                              +46.0C  n/a:                                                        N/A  n/a:                                                        N/A  n/a:                                                        N/A  n/a:                                                        N/A  n/a:                                                        N/A  
How do I know what tempX mean in sensors output?

It seems you could do this by editing the /etc/sensors3.conf file as discussed here. To have sensors use describing labels like above, you can add the  following section to /etc/sensors3.conf, if not already there. Use the  sensor location findings below.You could add the details as below. chip thinkpad-isa-0000   label fan1   Fan   label temp1  CPU  label temp2  HDAPS   label temp3  PCMCIA   label temp4  GPU  label temp5  System battery (front left, charging circuit)   label temp7  System battery (rear right)   label temp9  Bus between Northbridge and DRAM; Ethernet chip   label temp10 Southbridge, WLAN and clock generator   label temp11 Power circuitryYou could probably get information about your model from here.
