Overview
A quiet home office PC or a silent build is where these fans belong. Each unit is a black square frame with a fluid dynamic bearing and a four-pin connector, and a zero RPM mode switches it off at very low control signals.
The reason to buy is a multi-pack of low-noise fans with a wide speed range for quiet systems. The limit is the conflicting speed figures and the lack of any lighting or mounting hardware details.
Who it's for
Picture a quiet workstation where several matching fans handle intake and exhaust. A builder who wants lighting effects, or a single fan only, will find a pack unnecessary.
Pros and cons
- Five matching fans
- Zero RPM mode at low signals
- Fluid dynamic bearing
- PWM speed control
- No lighting listed
- Top speed given two ways
- Mounting hardware not listed
- Pack of five may be too many
Performance notes
A PWM signal on the fourth pin sets fan speed across the listed range, which lets the motherboard trade noise for airflow. At very low signals the fan stops, which silences idle systems. The fluid dynamic bearing holds friction low for steady quiet running.
