Light-Up 120mm Fans With LEDs
In addition to the 80mm fans, there are also 120mm models. The advantage of these is that their revolutions per minute can be much slower and still move the same amount of air. Not only does this have a mitigating effect on noise levels, but the lighting effects are also more clearly visible. With some models the redating blades seem to "pull" the light along with them, so it looks like the light from the LEDs is moving in the direction the fan is turning. The more LEDs the fan has, the more pronounced this effect.
A 120mm system fan costs between $7 and $20 depending on the colors and number of LEDs.
