hi, i have an acer aspire 5520 with amd turion 64 X2 and found that it is running very hot. i installed speedfan and the temperature of the Gpu and Cpu when i'm using the internet and listening to songs is around 70 degree celcius. is this ok for the laptop or will it damage it? also what is the maximum temperature before it will cause damage?Thanks. other specs is 2gb ram, 160gb hard drive, nvidia 8400m G
