Rainbow LED Dual-Ring Hydraulic Bearing 11 Blade Fan

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 classification of the mechanical bearing used in a product, such as ball, sleeve, fluid dynamic, hydraulic, magnetic levitation or other specialized types. It indicates the internal design that determines load capacity, noise level and durability.

The colour or combination of colours that a product’s outer shell or enclosure is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the case for consumers.

The highest electrical current a device draws from its power source during normal operation, expressed in amperes (A). It indicates the maximum current that the product requires and helps users verify compatibility with power supplies or sockets.

The physical interface used to connect a fan to a power or control source, such as 3‑pin, 4‑pin PWM, Molex, or other proprietary connectors. This value indicates the shape and pin configuration of the fan’s plug so that compatible power supplies, fans, or controllers can be selected.

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 vertical dimension of a fan measured from its lowest to highest point, expressed in a physical unit such as millimetres, centimetres or inches. It indicates the size of the fan that can be installed in a computer case, cooling system or other equipment.

The mass of a fan expressed in a standard unit such as grams or kilograms. It indicates how heavy the fan is and can be used for shipping calculations, handling instructions, or consumer information.

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

The color of the LED lighting on a product, indicating whether it has no LEDs, solid RGB, ARGB, or a specific single color such as Red, Blue, White, etc.

The total number of operating hours a product is expected to function before it requires replacement or major maintenance. This value represents the cumulative runtime from first use until the end of its useful service life, typically expressed in hours.

The total count of individual cooling fans that are part of the product or its components. This value indicates how many separate fan units are installed, such as in a graphics card, CPU cooler, case, or other hardware assemblies.

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.
