L420 overheating right palm rest and temperature values.

[yaro]

I have an i2310m 8gb ram 320hdd and after some time the left side palm rest is alright, but the right one burns my wrist.

Could anyone also decode 

temp1: +47.0°C
temp2: +0.0°C
temp3: +47.0°C
temp4: +0.0°C
temp5: +32.0°C
temp6: +57.0°C
temp7: +27.0°C
temp8: +57.0°C

What each of these mean?
