Description

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.

Different fom 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...

With the Rev. 3 of the BlackSilent series you purchase a reliable product optimized for silent operation.
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 80, 92 and 120mm.
There are 2 versions of each size: The version 1 is almost inaudible and intended for standard systems, the version 2 is almost not noticeable in operation and developed for more powerful systems.

The bearing used is a longlife floating bearing.
