laptop overheating / cleaning, opening it up

[ekearney]

I have a laptop, a Lenovo 3000 N100(Carbondude Oxide!)

I'm living in a pretty hot area and AC usually isn't available.  It's also super dusty at times.  I'm trying to make sure that I keep my PC as cool as possible...

I was wondering if it is a good idea to open it up to clean out any accumulation around the fans or heatsink.   Any ideas?

Thanks
