Overview
Not a lighting accessory, this be quiet! unit is a straightforward PWM case fan for a desktop tower. The motherboard varies its speed, and a rifle bearing supports the rotor.
The reason to buy is quiet running at low speed with room to spin up under load. The limit is that the listing gives no fan dimensions beyond the size in the title, and the contents are described only as one package.
Who it's for
A builder replacing a loud stock fan or adding airflow to a silent-focused case will use it as intended. Anyone after RGB effects or a multipack should look elsewhere.
Pros and cons
- PWM speed control
- Low minimum speed
- Wide speed range
- Rifle bearing design
- Mounting hardware not listed
- Single fan only
Performance notes
A PWM signal from the motherboard changes the fan speed with temperature, so noise stays low at idle and rises only when needed. The stated air flow is a maximum figure at top speed. Case layout and any dust filters change the real airflow.
