AC fan kit keeps your network equipment from overheating for stable performance and longevity. The fan easily installs to the fan panel and in any 120mm x 120mm standard location in your enclosure. Operating at a quiet noise level (43db-A to 47db-A Max), the fan does the important job of keeping even full loads cool. Applications include fan/cooler panels or trays, network, server and A/V cabinets, and computer cases.
