The loudest sound intensity produced by a product during normal operation, expressed in decibels (dB). This value helps users assess whether the device will be suitable for quiet environments or noise‑sensitive settings.

The highest rotational speed that a fan can achieve, expressed in revolutions per minute (RPM). This value indicates the maximum airflow capability and potential noise level of the fan under full load or when operating at its peak performance.

The maximum amount of heat a processor or component is designed to dissipate under normal operating conditions, expressed as power in watts (W). It indicates the upper limit of thermal output that cooling solutions and system design must accommodate.

Indicates whether a product includes a mounting kit that allows it to be securely attached to a wall, rack, or other support structure. The value is typically "Yes" if the kit is included, or "No" if it is not.

The total count of fan units included in the product. This value indicates how many separate fans are present, which can affect cooling performance and noise levels.

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

The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.

The form of packaging used for a product, such as box, blister pack, bag, or pallet. It indicates how the item is contained and protected during shipping and storage.

The horizontal measurement of a product’s packaging, expressed in a linear unit such as millimetres or inches. It indicates how wide the package is from one side to the other and helps customers assess fit for storage, shipping, or display.

The total count and type of electrical connector ports available on a pump, indicating how many distinct connections (e.g., 4‑pin, USB, RGB) can be used to interface the pump with other components or power supplies.

Indicates whether the product includes a Pulse‑Width Modulation (PWM) fan or is compatible with PWM control for variable speed operation.

The overall size of a radiator expressed as width × height × depth, typically in millimetres or centimetres. This attribute indicates the physical envelope that the radiator occupies and helps customers determine whether it will fit into a computer case or other enclosure.

The overall linear dimension of a radiator, expressed as a single numeric value followed by a length unit such as millimeters or centimeters. It indicates the physical width (or height) that the radiator occupies and is used to determine compatibility with mounting brackets, chassis space, or other components.

The electrical current that a device is designed to draw or supply under normal operating conditions, expressed in amperes (A). It indicates the typical power consumption or output capability of the product and helps users assess compatibility with power supplies, sockets, or other components.

The number of times per second that a display updates its image, expressed in hertz (Hz). It indicates the smoothness and responsiveness of motion on the screen; higher rates generally provide a more fluid visual experience.
