Motherboard Temperature at idle

Hy everyone, my laptop lately has been acting up, the motherboard temperature at idle jumps randomly up 60, i have ran several antiviruses and malwabytes programs and my laptop is clean, i have checked every processor running in the background and nothing seems to be off, just recently i got my laptop cleaned and i noticed major improvement in temperature, it might seem weird but if im using any program temperature doesnt raise above 50, i even play MW2 and it says below 60, but as soon as i get off my laptop after about 10 to 15 minutes motherboard temp jumps to 60 and goes down while the cpu stays in range between 42 and 45.
My hands are tied, im really confused about this, i would appreciate any help.

My specs:

Hp Pavilliong6
I5 2.6GHZ
500HDD
Inter HD Graphic 4000
4GB of RAM.

I know what do you feel . . .

the only thing I tried is dual booting windows 7 with windows 8

but before doing this create recovery drive using AOMEI onekey recovery

this will install image on partition

when SEIROUS error occurs while booting recover it
