Описание товара на английском языке:
Very quiet operation
Low-noise operation due to high-quality rifle bearing. The parallel arrangement of recesses on the outer side of the bearing shaft ensure uniform circulation of the high-quality oil and make the fan very quiet. Mechanical noise is minimized by antivibration fasteners and the rubberized fan frame. The high-quality IC motor controller reduces electrical noise sources.
Long service life
Reliable cooling for up to 200,000 hours thanks to the high-quality rifle bearing.
High air flow
The flow-optimized surface structure of the fan blades produce more air flow in combination with smooth running.
Screwless installation makes handling simple.
