The Hardware Reviewer looks at a few Crystal LED Fans... They're not as pretty
as the Antec's but they're quite cheap.
What we have here are three Crystal LED fans, each being made of clear plastic,
measuring 80x80x25mm, with different features. The one on the left is just a
regular fan with blue blinking LEDs, the middle one is thermal controlled, and
the one on the right has a switch that controls the fan speed. The regular fan
has different specifications than the other two controlled fans, as seen below
on the back of each package
