Heat is the number one killer of PC's and especially laptops. Thasher is spot on with this. if you have an air compressor, be sure to place a paperclip within the fan as to not spin out your bearing but good air pressure will help get those dust bunnies out! Just hope that video card will live if you have a cloged up fan or just dust build-up! Remove the battery and anything that is easy to remove, CD Unit and such! Blow via the exit ports and all the cracks you can and hope for the best. Never sit your laptop on carpet, beding, pillows and such as I have seen a many die from this as well. The fact that your fan is WOT means the thermal sincer knows it's hot and trying it's best to cool her down! Hope this all works out for you!
Thanks for all the ideas. I'm going to fool around with it some more tonight and see what I can come up with.
