Noiseblocker Black Silent Pro PK-3 140mm Computer Case Fan by Blacknoise

The Premier League with a Classical Design
Developed with and for our discerning customers, the new (((NB))) Premium range of fans - equipped with a classical frame and rotor blade - combines the NB-BlackSilentPro series with the latest high-technology in a tried and tested design.

The high-quality NB-EKA Plus II drive and the almost noiseless NB-NanoSLI bearings guarantee operating noise levels which are particularly low over the long term - both equipment features which until now have only been used as part of the costlier Multiframe Reference series.
