Unfortunately, all the brands mentioned are flunked in size 60mm with me as too loud or annoying sounds. It is a QNAP 212P are cooled in the living room. Even with the fan potentiometer began to squeak or to give milled at low speeds noises.
The Noctua is the first 60s of REALLY is silent.
Negatives:
- Fairly high price, but rather once expensive than twice cheap.
- Color of getting used to (no point deduction)
Positives:
- Great accessories, with various cables, change the speed
- Rubber buffer
- Absolute silence, only the draft is at higher speeds from making
Would buy the fan again!
