Low FPS with decent-good performance. HELP ME!

[WOORM]

Hello, I have only 20-30 FPS in average battles with this performance:

Intel i7-3610QM 2.3Ghz
Geforce M 660 GTX
12 Gb RAM

I have read a lot of guides and tried alot of UserOptions settings but in average fights i got only around 25 FPS even with low settings or ultra (without shadows and other stuff). :!:

It's hard to play with 25 FPS so I need at least 40 FPS to play smoothly.

Is it possible that temperature blocking my FPS?
My CPU temperature during the game is around 90 degrees celsius. And thats alot!
So I thought maybe I should buy cooling pad for my laptop and then unpark my cores. Would this help me get more FPS?
What you suggest me to do? I need your help. :?:

(Sorry for bad english i'm from Slovenia and i can't really speak english very good)

THANKS!
