I use Ubuntu.
I installed lm-sensors
and this is the output I get when I run "sensors".

acpitz-virtual-0
Adapter: Virtual device
temp1: +65.0°C (crit = +100.0°C)
temp2: +65.0°C (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +57.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +57.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +57.0°C (high = +86.0°C, crit = +100.0°C)
Core 2: +57.0°C (high = +86.0°C, crit = +100.0°C)
Core 3: +57.0°C (high = +86.0°C, crit = +100.0°C)

nouveau-pci-0100
Adapter: PCI adapter
temp1: +56.0°C (high = +100.0°C, crit = +110.0°C)

Core 0 to 3 must be the 4 cores of my quad core processor ,if I'm right.
and nouveau-pci-0100 is the GPU's.

What are temp1,and temp2?

Better install HWMonitor to get a more detailed Info

After some digging around temp1 is the CPU itself temp, temp2 is the system temp.

sorry for my ignorance , but what is "system" temp?
CPU is the processor, right?

Yup, System temp is the motherboard temperature, it may be taken at PWM or Chipset or anyplace the manufacturer chose to put the sensor.

okay , but if temp1 is the processor's temp , then why would the 4 cores' temps be shown separately?

There's a difference between CPU socket temp, and CPU core temp, usually CPU socket temp are a bit higher than core temp.

Thanks a lot for your help.
this is solved. But can you please tell me where I might find the optimum temperatures for them all?

Optimum temperatures. The "alright" temperatures for my laptop.
I need to know when I should worry about overheating.
I bought a decent cooling pad , but the temperatures shown in "sensors" hardly drop.
I don't know where to find optimum temperatures.

Any temp below the 70C is great specially for the laptop, the cooler aren't gonna help that much.
