PURPOSE: A device for preventing the vibration of a fan of an LCOS(Liquid Crystal On Silicon) cooling system is provided to resolve the thermal deformation or the decrease of the elastic force of a vibration preventing element, thereby keeping the vibration absorbing property for a long term use. CONSTITUTION: A device for preventing the vibration of a fan of an LCOS cooling system includes a cooling fan(3) for cooling the heat generated from a liquid crystal display device, vibration preventing spacers(21) each coupled with the cooling fan at an end and including a spring element of a predetermined elastic force to absorb the vibration of the cooling fan, and a heat sink(7) separated from the cooling fan by a predetermined distance and coupled with the other ends of the spacers for absorbing the heat and supporting the liquid crystal display device.
