I meant, give me a percentage. Is it on 10 or 20% all the time?
ATM, my fan is spinning but quiet. My CPU usage is 8-15% and "PC Wizard 2010" says that my Core Duo DTS temp is 50°C. If the laptop is new, as in just assembled, then maybe the thermal-compound used on the CPU is settling in, and this process sometimes takes 3-6 days before good cooling is achieved.
If you're worried, u should contact Asus and ask them what's the normal temp. At least it will be recorded on their system in case it becomes a real problem later.
