My toshiba satellite rising up to 75 to 80 celsius(i use coretemp) when cpu load 100% at more than 30 seconds durations. The tasks is System, service hosts, windows update and softwars update(on task manager). Also i have a cooling pad, my laptop is clean also no dust inside. It still happen since my laptop is new. But it is normal to reach that??? Because many others says it is normal...
