NBFAN offers the worlds first patented air extracting notebook fan, which quickly helps to remove the heat build-up customary in most notebook environments, while a 180° rotatable vent means that you can control the direction the expelled heat will take as it leaves the notebook. Perfect for virtually any environment, NBFAN provides selectable dual-speed operation, allowing you to control the noise level of the fan, based on your surroundings. The simple unobtrusive design blends nicely with most notebook computers, & features a sleek black finish that matches or complements most notebook designs.
