With this heatwave upon us I started boiling in my home office. Looked into AC options, but I have "crank open" windows so that idea won't fly. Just picked up one of these fans from Crappy Tire:
This thing is awesome! Very quiet and even at the slowest speed (of the three) it blows quite a bit of air. I have it sitting about a meter away from me right now and don't feel hot at all. If I turn the fan off for even a few minutes the room temperature becomes unbearable; this fan makes that much of a difference!
It rotates, has three speed settings, a timer, remote, "night mode," and even a useless blue LED light at the bottom. Recommended!
