I have a HP Compaq nc8430 laptop with Intel Core 2 Duo T7200 2.0 GHz processor, 1GB Ram, ATI Mobility Radeon X1600 256MB. It's about 1.5 years old I would say.
My Acer notebook is configured equivalently. The CPU temperature also behaved similarly and since sommer it was getting just worse. I gad to operate at very low frequencies in order to suppress annoying fan noise. When loading both CPU and GPU (CPU, GPU and possibly some other heating stuff on the mainboard share one heatsing and fan), the temperature was jumping over 90°C - therefore I've set a limit event at 85°C in the Pro features to throttle the frequency, until the temperature gets lower.
Finally I had to open the notebook case and found few dust bunnies on the inner side of the cooling ribs, blocking maybe 1/3 of the air flow. I took them out and additionaly cleaned the area between single ribs with inter-tooth brush.
Now: even when idle, it also never gets under 50°C under usual room temperatures (with fan running on the lowest sped). Under full CPU load, it gets to around 65°C (second fan speed), with additional GPU load the temp goes somewhere to around 70°C (and fan revolutes on the third speed). Maybe it will get worse during hotter summer days.
