MacBook Pro with Retina Display is normally 80°C hot. Is it normal?

Hi friends,

I would like to know if MacBook Pro with Retina Display is normally 80°C hot when doing mostly any kind of work besides reading the screen.

I tried to document this with some screenshots.

It is getting more than 80°C too frecuently and I think that fans are activated after 90°C or so.

If I manually activate them with smcFanControl tool then temperature goes down.

The laptop is quite new. it has 3 months old.

I am not sure, but I think that it wasn't getting that Hot before.

May it be possible that an upgrade changed the upper margins for the fan activation ? It has OS X 10.8.5.

I live in a very cold place and it gets really hot even on the table, but if I were on a business travel to other hotter places, would it burnout ?

I have buyed the most expensive computer on the world to not have this kind of problems. Will it be fixed soon?

I would appreciate any help.

Saludos

Diego
