The (((Noiseblocker))) BlackSilent series is an inexpensive and reliable ultra silent fan series. The fans are developed in Germany and feature extremely quiet operation as well as high reliability.
Other than the most cheap fans the low noise levels remain for years of operation on their low level.

The reason is the choice of materials and precise manufacturing.
Other than 95% of the so called ''fan brands'' (((Noiseblocker))) develops the fans themselves and uses high quality parts even in their ''cheap'' fans.
The BlackSilent fans are simple and solid fans with quality components that naturally have their price.

Unlike other competitors we give only realistic and serious technical data.
We leave it to the customer to judge claims such as ''400 000h MTBF'' (provided by multiple competitors). By the way: 400 000 hours are more than 45 years...


From now on we include NB-Slics (vibration absorbers) with the 80&92mm retail fans as well as screws with the 120mm versions.
The further improved quality makes us confident that we can elongated the warranty period by one year to 3 years.

The fans are available in the sizes 40, 60, 80, 92, 120 and 140mm.


Als Lager kommt unser besonders langlebiges NB-NanoSLI ® Gleitlager zum Einsatz.

The failure rate was furthermore improved and is now 0,001% (before 0,15% of 100 000 units p.a.)
