I keep my MacBook on a USB cooling pad with 3 fans & as long as I remember to turn it on, the computer runs cool & the internal fan never comes on. Since updating to 10.4.8, the internal fan comes on fairly frequently. Has anybody else noticed increased fan activity since upgrading?

Did you update it with the firmware that came out about a month ago?

I just went to 10.4.8 on my new MacBook Pro last night (my 15" MacBook Pro is about 1 month old). By the way, how do I know when the fan is on or not? Can you hear it? Is there a control panel that says its on?
I'll have to check the firmware. I believe I checked it right when I opened it up and it was current.
