Gelid Sirocco RGB Quiet CPU Cooler

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 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 specific model or design of a fan used in a product, such as size (e.g., 80 mm, 120 mm), bearing type (e.g., fluid dynamic, rifle, ball‑bearing), noise level, and any special features like PWM control or RGB lighting. It helps users identify the fan’s physical characteristics and performance traits.
