I have a Toshiba laptop, and I have noticed that my "cooling"/ventilation fan on the under portion of the laptop has collected a relatively good amount of dust on the blades of the fan. There are times I believe that my laptop might be running somewhat hot. I am not certain if this dust build up is facilitating this temperature situation... or if I am just over-sensitive to it because I think it might be a problem. Is there a way I can remove this dust without running the risk of causing some sort of damage to the laptop? I appreciate the feed back!
