Connectland USB Desk Fan
One of the problems of working in an office with a lot of computers is that they generate a lot of heat. I've found that typical office central air conditioning systems simply aren't designed to siphon off the hot air generated by computers fast enough. I've had a small USB fan/light combo for a while now and decided to look for something slightly bigger to push a bit more air in my direction. The Connectland USB desk fan just arrived yesterday ($13 from Amazon with free shipping).
The fan stands a mere 7 inches tall. And, as you can see from the photos, it is powered by plugging it into a USB port. I just unpacked it and tested it out. It is not exactly silent. But, it is quiet enough for my needs. It pushes out enough air for my needs. And, unlike the USB fan I'm using now, it can rotate on its base.
I'm apparently the first person to give it a rating on Amazon.com. And, I gave it 4 out of 5 stars ("I like it").
