Description
Networking Devices (Routers and Switches)
Heavy-duty network switches or routers that run 24/7 generate a lot of internal heat. A 4020 fan is used inside them to exhaust hot air so the device doesn’t hang or slow down your internet speed.
CCTV DVR/NVR
The box (DVR) that records CCTV footage contains a Hard Drive that gets very hot. To keep the hard drive cool and prevent data loss, a 40mm fan is often installed on the side of the casing.
Small Projectors
Portable or LED projectors generate significant heat from the bulb and internal chips. Because the projector body is small, a 4020 fan fits perfectly to provide necessary cooling.
DIY Projects and Inverters
In small home-made 12V inverters, battery chargers, or power supply units where space is tight, this fan is the best choice for cooling.
Key Specifications to Remember:
- 40mm: The length and width (roughly 1.5 inches).
- 20mm: The thickness (A 20mm “thick” fan usually provides better air pressure than thinner models).
- 12V: It operates on a standard 12-volt DC battery or adapter.
