I'm not much of a laptop guy but 79c would seem a bit high for laptop. Considering the lack of thermal solutions and that heat easily transfers to all the other components affecting them as well. Also got to note while cooling pads may seem good in theory sometimes in real world scenarios they aren't a good idea. You have to consider those fans are forcing air through the chassis which, negatively, forces more dust through as well... All this dust gets trapped in the fins of heatsinks thus affecting the cooling solution more so.
I'm not saying cooling pads are bad, just limit the airflow... Someone mentioned that not to take the machine apart if it's under warrantee and I'd have to agree. Call the manufacturer...
