Noctua NF-F12 iPPC-2000 IP67 PWM

The total number of screws that come with a cooling fan or similar component, indicating how many fasteners are required for installation.

The total volume of air that a product can move, expressed in cubic meters per hour (m³/h) or cubic feet per minute (CFM). It indicates the overall ventilation capacity and is useful for comparing cooling performance across fans, heat sinks, and HVAC units.

The mechanical design of a bearing used in a product, such as ball, sleeve, fluid dynamic, hydro‑dynamic, or hybrid. It indicates the internal geometry and lubrication method that determines load capacity, speed range, noise level, and suitability for specific applications.

The colour or combination of colours that a fan is available in, expressed as common names such as "Black", "White" or comma‑separated lists like "Black, White". It indicates the visual appearance of the fan for consumers.

The linear measurement of a fan from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the fan is and can be used for fitting, compatibility, or spatial planning.

The linear measurement across the widest part of a fan, expressed in units such as millimeters (mm), centimeters (cm) or inches (in). It represents the overall width of the fan and is useful for determining fit, compatibility with cases, and airflow characteristics.

The rotational speed of a fan expressed in revolutions per minute (RPM). This value indicates how fast the fan blades turn, which affects airflow and cooling performance for the component it serves.

A list of the operational states that an LED indicator on a device can display, such as power status, activity, link, or other functional signals. Each entry represents a distinct status that the LED may show when the device is in use.

Indicates whether the product allows manual adjustment of its operating speed, such as a fan or motor that can be set to different RPM levels by the user.

The material indicates the type of substance from which a product is made, such as metal, plastic, wood, glass, or composite materials. It helps users understand the product’s durability, weight, appearance, and suitability for specific applications.

Indicates whether the product includes Pulse‑Width Modulation (PWM) control for fan speed or other components, allowing variable speed adjustment via a controller.

The overall dimension or measurement that identifies the size of a product, such as a frame, garment, electronic component, or container. It can be expressed as a single numeric value (e.g., 47 mm), a range (e.g., 50–60 cm), a volume (e.g., 700 ml), or a descriptive label like "One Size". The attribute helps customers compare and select items that fit their needs.

The intensity of sound produced by a product, expressed in decibels (dB) or sones. It indicates how loud the device is during operation and helps users assess suitability for quiet environments.

The electrical potential difference that a device is designed to accept from its power source, expressed in volts (V). It indicates the nominal operating voltage for the product and helps users verify compatibility with local mains or battery supplies.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
