The Primacoustic Machine Room Computer Silencer is a computer silencer that combines natural thermal convection with forced air to keep your computer running at ambient temperatures. Cool air enters the Machine Room via a port equipped with a dust fi lter at the bottom rear. A distribution chamber evenly dissipates fresh air around the computer while the variable-speed fan in the top draws the warm air out via a noise attenuating manifold. High density wood composite shell, internal acoustic foam and isolation pads combine to attenuate noise. A sealed Plexiglas front door and rear cable port provide effi cient access to the computer. Comes with fan power supply and wireless remote thermometer to monitor internal temperature.
