This DDS 1U network rack cooling fan assembly fits all standard 19″ racks. It helps to keep equipment cool by heat dissipation. An On/Off switch is located on the front of the unit. This network rack cooling fan includes 4 mounting holes for easy installation. It is the perfect add-on for improving ventilation in your server cabinets and rack enclosures, supplying a healthy air flow stream to keep your equipment cool. Improvements to air circulation not only help to keep your valuable rack components cooler, but it also improves the system performance and prevents costly equipment failures later that could result in interruption, damage, or even loss of data. When you have an empty slot in your enclosure, instead of just a blank panel, try one of our network rack cooling fans to help keep good air flow within the cabinet. Fan trays are used to remove the heat from the rack and are placed where there is a hot spot. The area may become hot because of insufficient circulation, for example, if there are no facilities at the top of an enclosed rack, you’d put a fan tray here, to get the air moving and stop the excess heat. When hot spots form, network rack cooling fans also move heat away from the server, but it pushes it out of the back rather than pushing air up or down. This is because, if the air were to be pushed upwards, it would be at risk for recirculating warm air back into the cool area. Show More Show Less
