Super to 5 volts.

Note:
I have the 80mm F8 2000rpm fan not be Rotate 100 hours at 12 volts to let einlauffen around him.
(Too lazy.) So it is possible that he is still minimal changes or further improved its sound.

2 pieces are in use in the PC, a blow fresh air into it and leads it off.
Both unentkoppelt with standard screws directly run on the housing at 5 volts:
- Pleasantly mild airflow.
- Quiet fan noise.
- Subjectively pleasant fan noise, not too high, not too low, not swirled.
- No loops despite 5 volts.

Tiptop as a case fan for medium housing!
