Description:

With a life expectancy of 100,000 hours, the Minebea NMB line of fans have one of the longest MTBF ratings we have seen. Leave it to the folks over at NMB (Minebea Matsushita Corporation) to create a highly efficient fan that caters to everyone's needs: high-flow, low-noise, and long-life. NMB, the maker of the Panaflo line of fans, has been long regarded as one of the premier fan manufactures in the world, and with the release of the Minebea NMB fans, their reputation can only improve with even more prestige. These fans have been specifically designed with a special, silent IC to reduce the typical switching noise commonly associated with computer case fans.

Features:

• Outstanding Long Life of 100,000 Hours: With all in-house development and high quality parts used in this case fan, the MTTF (Mean Time To Failure) is up to 100,000 hours, which is beyond the limit of standard ball bearings in the market.
