Fans - How Many on MB C2D?

[Gosh]

Hi,

Have a new MacBook (C2D).

Fan/s seem to run up without much more than Safari running, and when sat on a table (rather than my lap).

Have Fan Control 1.1 Program http://www.lobotomo.com/products/FanControl/ which show one Left Fan at "say" 5000rpm but Right Fan at -1rpm!?!

I know MBP has two fans but anyone know how many in MacBook?

There is ONE fan in the MacBook C2D... I know that because I have one

And of course because of this, the second fan in your app is not reported. The ProBooks have 2 fans, thats what it is for.

Oh and by the way, the fan should only spin up if the CPU usage goes up. That means even in Safari, depending on the page content, the fan may spin up. For example flash movies (youtube and such) or a ton of animated GIFs can make the CPU go up.

Thanks - quite worried there for a bit. Still seems to rev up and stay high for no apparent reason. But it is my first Apple notebook so a bit of getting used to it I suppose. The little 'Fan Control' app I think is quite useful to trade a little fan noise for quieter running!

MAYBE you have something installed and running in the background that eats CPU... maybe a Rosetta (non-Intel native) application.

Launch Activity Monitor in the Utilities folder and check which app may drive your CPU usage up.

A friend of mine recently purchased an iMac and suddenly it wouldnt switch off/log out properly anymore. I found then out that he had an old (2003) printer driver installed, which was of course PPC only and caused the trouble.
