if a rear case fan is fitted i would have the air removed from rear blowing out of case, the same way the power supply does, as with the cpu fan speed it is a 3 wire lead yes? and pluged into cpu socket correct not into the case fan socket? with the psu fan speed theres no monitor lead in the atx power lead so theres no way to know the speed, look in your mobo bios and adj the shut down temp for your cpu, speed reduction for intel cpu are with the centrino chip for mobile computers not desk top systems, best start would be to lower your inside case temp to as close to the outside temp 21 or less some people like there homes hotter (wont help), also has the heatsink have thermal paste? make sure its a very thin layer, also lapping the bottom of heatsink with wet and dry paper on a sheet off glass will give better contact with cpu...
