Why does my powerbook fan run all the time (when external monitor is connected)?

I have a 15" 1.67 powerbook with 2g of ram. I just recently purchased a 20" wide dell monitor. Everything is great, except that when my monitor is connected to the powerbook, the fan is always on. Even when all I have running is safari, thunderbird and a few widgets. The only time it stops is when i put the computer to sleep, or turn it off.

The monitor is connected through DVI and I also have a usb cable running from the monitor to my powerbook.

Is it ok to have my pb fan to run all day long?

Your video card is working overtime to drive both the internal display and the external monitor. It's not a problem, but make sure the area around your Powerbook is well ventilated. Just make sure to leave the lid all the way open.

I have a 12 inch PB which is hooked up to an external display for about 30-40 hours a week. And this has been going on for over a year. And yes the fan is on the whole time but mine is fairly quiet.

Also discussed here and other forums.

Try a chillpad (you know the laptop cooling pads).

They have two or three fans usually that pull heat away from the laptop. If it's a temp thing this might help keep your internal fan from running and the chillmat I have (targus) is silent.

Alternatively, bottle caps under the feet work well to increase airflow.

This summer my Powerbook fan came on a lot and made me pretty nervous, so I downloaded the free version of Temperature Monitor, which I found out about from an earlier question here, and I was completely reassured by what it was able to show me.
