AN8 32X PWM location

ok does any one know where the pwm is on an abit an8 32x. for some reason my temps are way to high and i don't know where it is on the board so i can cool it off. want to put a small cooler on it. I am using a vapochill so i don't know if the temps are even right some say that going that cold messes with temps form the MB.
any help on location would be nice.
