How Come When I Start Using iTunes

[AppleTecFan]

How Come When I Start Using iTunes the temp of my CPU goes from 45C to 71C
This only happens when I run iTunes
I use SMC Fan Control its at 3500 RPM when I'm off the charger and when I'm on, 4500 RPM

And what is the average temperatures for a macbook pro (in celsius)

Nothing?

Avg temp should be easy to find with a little googling.
iTunes is a bit of a resource hog, so while I can't say much about the temp jump, it definitely uses more processor which means more heat generated.

Do you have an especially huge iTunes library, or some plug-ins, or are you using coverflow, or the "visualizer"?

iTunes must be doing something CPU intensive. Try clicking the little arrow in the monochromatic display in the top part of the iTunes window to cycle through the tasks that iTunes is doing.

Are you using the visualizer? Do you have "sound enhancer" on? (preferences->playback->uncheck Sound Enhancer to disable it) Both of these will use extra CPU time.
