Hey all. I was wondering if anyone else has issues with the fan kicking on all the time on their 12" powerbook while it is in clamshell mode hooked up to a 20" Dell Widescreen monitor? I'm not all that worried about it but would anyone recommend a good product for cooling the powerbook so its fans don't wear out? I know there are prodcuts you can put under the powerbook with fans that cool it but I was hoping somone could recommend a good one for me. Thanks!
