Overheating problems

Hi!
First i want to say that i love this game!I bought the day before the public beta weekend and it worked perfectly throughout the weekend. After this i took a break and picked up a few days ago.

Now to the bad thing, when i started playing a few days ago i encountered a problem which wasnt there before. After a few minutes ingame my pc just dies, after some testing i confirmed that i was my cpu which was overheating.

RealTemp showed after some gameplay in the area The Prisoners Gate(if it matters)cpu temperatures at almost 90 degrees. I play ArmA2, GuildWars 2 and Dota2 among other games without a problem on this laptop and PoE worked fine during the public weekend.

My specs are http://www.asus.com/Notebooks/Versatile_Performance/K55VM/#specifications with the Intel® Core™ i7 3610QM Processor and Win7 Home Premium.
