This case fan has finally managed to build us now a silent HTPC. The fan is supplied complete. Screws, rubber fittings and all sorts of wiring options. Nothing was missing. The manual is stringently and installed the fan with a little skill in 5 minutes. The speed control is on our board completely smooth and finely adjustable. We can recommend this fan unrestricted.
