I'm using Samsung 5 Series NP535U4X-S01ID with specification of AMD Quad-Core A8-4555M processor and AMD Radeon HD 7600G + HD 7550M Dual Graphics.

I've just installed Ubuntu 12.10 and I use the AMD nee ATI: Thames [Radeon 7500M/7600M Series] driver which is recommended by the ubuntu software sources.

But after I update to this AMD "recommended" driver, my average laptop temperature rise up to 75C. Is this normal? Or what should I do to reduce the average temperature?

(The fan sounds loud right now.)
