A 5V fan with dimensions of 8×8 cm (80×80 mm) is a medium-sized cooling device commonly used in various electronic and computing applications. Here are the key features and specifications of such a fan:

Key Features:

1. Voltage: 5V DC
2. Dimensions: 80×80 mm (8×8 cm)
3. Connector: Typically equipped with a 2-pin, 3-pin, or 4-pin connector for easy integration.
4. Bearing Type: Options include sleeve bearing, ball bearing, or hydraulic bearing for increased longevity and performance.
5. Noise Level: Designed to operate quietly, suitable for noise-sensitive environments.
6. Airflow: Measured in CFM (Cubic Feet per Minute), indicating the volume of air the fan can move.
7. Speed: Measured in RPM (Revolutions Per Minute), indicating how fast the fan blades spin.
8. Mounting: Usually comes with pre-drilled holes or slots for easy and secure mounting in various devices.

Typical Applications:

• Desktop Computers: For cooling CPUs, GPUs, and other internal components.
• Networking Equipment: Used in routers, switches, and other networking hardware.
• Home and Office Electronics: Utilized in devices like printers, projectors, and home entertainment systems.
• Power Supplies: Ensuring efficient cooling of power supply units.
• Industrial Equipment: Used in control panels and other industrial applications for thermal management.

Example Specifications:

• Voltage: 5V DC
• Current: 0.15-0.35A
• Power Consumption: 0.75-1.75W
• Airflow: 20-40 CFM
• Noise Level: 20-30 dBA
• Speed: 1800-3500 RPM

Installation and Use:

• Connection: Connect the fan to a 5V power source, ensuring proper polarity.
• Mounting: Secure the fan using screws or clips in the designated mounting area, aligning with the pre-drilled holes.
• Maintenance: Regularly clean the fan blades and housing to prevent dust buildup, which can reduce efficiency and increase noise.

Summary:

An 8×8 cm 5V fan is an essential component for cooling a variety of electronic devices, providing a balance of airflow and noise level suitable for both consumer and industrial applications. Its medium size allows it to fit into many different devices while still offering substantial cooling capabilities to ensure optimal performance and longevity of electronic components.
