When it seems that the possibilities are depleted when talking about new features and variations, the manufacturers try to invent something different and it is what Revoltec made with the Fan LightWriter. Kinda innovative, this Fan shows the temperature using Led’s that when the fan is working, it makes texts and effects. Very cool!!

With the price around €15, your rotatoin speed is about 2.000rpm and makes around 29dB of noise and air flow of 17CFM.
