AAB Cooling NC81 Black Laptop stand is yet another AAB COOLING laptop cooling tray, which has five efficient and quiet fans (1 x 120mm and 4 x 70mm)! Ideal for large laptops up to 17 ". The gaming laptop cooling provides a stable base for your laptop, while the rotary potentiometer enables simultaneous fan adjustment. Five fans take cool air from below the laptop fan cooler and direct it to the laptop surface while providing low noise emissions.Hydraulic bearings work very quietly. When setting the lowest fan speeds, noise is practically inaudible (SUPER SILENT mode). The lower part of the laptop lap fan has a 5-step tilt adjustment to ensure the highest ergonomics. An additional advantage is the small legs that increase the angle of inclination in the flat position, the anti-vibration pad and the blocker to prevent slipping of the laptop.
