hi, i have a macbook late 2008 unibody aluminium. since 1 or 2 month i hear my fan a more often than before, so today i installed smcFanControl to check whats going on. when i reboot the macbook the cpu is at 40-50 C and the fan runs at 1800rpm. than i start google chrome and iphoto 11 and when i browse some pictures, immediately the heat goes up to 70-80C and some seconds later the fan runs at 6000-6500 rpm! and it sound like a starting airplane.... is that normal? is my macbook to old to run google chrome and iphoto? i have 2ghz and 2gb ram. just the standard configuration. any advice???
