The Mini Cooling Fan Pen ($9.46) is a great alternative if you don’t want to clutter your desk with an extra gadget, such as the Mini Cooling Fan.
This lightweight blue-ink pen comes with a cooling two-winged propeller fan. It requires a 1.5V battery (included) and is available in a variety of colors.
