The local Dollarama is selling a nice little USB powered fan for $3. It comes with a USB - to - Fan adaptor cable and provides a pleasant breeze. My wife is using a couple of them (plugged into USB power adaptors) to ventilate the seedlings that are sprouting in our kitchen. I got one in advance of the hot summer weather. I'm thinking it will be very convenient to plug into a front-mounted USB connector on my computer.
