Computer fan making a noise the turbo fan when watching a movie or using google earth?

Question by Rob: Computer fan making a noise the turbo fan when watching a movie or using google earth?
Why is it the turbo fan makes a noise when watching a movie or using google earth ? What math calculations is there for that? It not like playing a 3-D game or video editing where you need big GPU.. A P2 with windows 95 can watch movies or use google earth.

Why is the turbo fan on for that? the computer should not get hot for that it is not 3-D game like doom 3 or video editing it is just watching a movie or using google earth .There is no rendering for that.

My 8 year old computer does not make any noise.

The fan has 3 setting a sleep mode ,normal mode and turbo mode. And that seems to me the case with computers built from 2005 to now.

Before in the past it just ran normal no sleep mode or turbo mode , but the computers before 2005 the fan was louder than todays fan.But alot of computers have turbo fan for 3D games or video editing .

Anything that makes your computer work harder can heat it up and set up the fan to run faster and thus louder. Such as you could be running nothing at all and if your room is really hot, that will make your computer hot, and the fans will kick into high gear. And Video processing of a movie and google earth does take up a lot of video power.

Modern computers can generate more heat because they are more powerful and run faster than older technology, so they do get hotter and require more cooling.
