Sims 2 Vacuum Download Very High Gpu Temperatures, Please Help Me :(?

Very high gpu temperatures, please help me :(? - sims 2 vacuum download

Okay, so I have a BenQ S42 laptop with a 9600M GT. The temperatures are so high! For example, at 80C strike and when I play the Sims 3, but in the middle of the success of 100-110 time! OO. "Someone told me that changing the fan speed. RivaTuner I downloaded and could not get the speed with SpeedFan, and not remove the speed will not change, including through the NVIDIA Control Panel" Try to empty the dust from my GPU holes and nothing else happened. ~ I have tried to use a cooler, the temperature is dropped to 5 degrees in both __ ~!

HELP PLEASE! I want to die not my laptop! : @ @

If this helps, these are my details:
Intel Core 2 Duo 2.4 GHz, 3m (P8600 I think)
3 GB DDR2 RAM
NVIDIA GEForce 9600M GT with 256MB GDDR3
