Get a 4L black or white cooling fan with a remote control. Features three speed settings (low, medium, and high), so you can find the perfect ventilation flow for you. Alternate between normal, natural (speed changes from time to time), and sleep mode (gradually decreasing from high to low). Press the swing key to allow the fins to move left and right continuously. Add fresh cold water and press the button for ultimate cooling - you can even add a frozen pack for a stronger effect. Can be set at 30 min increments, up to a maximum of 15.5 hours. Comes with a remote control so you can choose your desired settings with a touch of a button. Offers strong air volume with minimal noise so the fan won't disrupt you while you work or sleep.
