If doing this (or using canned air) it's a good idea to use a small stick or bit of plastic to jam any fans to stop them spinning too hard and ruining their bearings or throwing a blade, both of which I've had happen. Laptop ones seem particularly susceptible, probably down to size and typically higher usage temps.
