Product information

Description

PRIMECOOLER PC-4020L05B 4020 5V is a compact axial cooling fan sized 40×40×20 mm, engineered for 5V DC systems. It delivers targeted airflow to remove heat from small electronic assemblies, single-board computers, network devices and enclosed spaces. The fan's compact footprint and standard mounting pattern allow integration into limited-clearance installations and custom cooling setups where a low-voltage, low-profile air mover is required.

Advantages

The fan offers steady forced airflow in a small package while operating from a 5V DC supply, making it compatible with USB-powered and embedded platforms. Its axial design provides effective directional cooling for heatsinks, chips and compact enclosures. The small dimensions reduce interference with surrounding components and enable placement in confined areas where larger fans cannot be used.

Suitable for

Cooling single-board computers and mini PCs
Ventilation of network equipment such as routers and switches
Forced airflow in small enclosures and control cabinets
Cooling power supplies and compact electronic modules

Key specifications

Fan type: axial blower
Dimensions: 40 × 40 × 20 mm
Rated voltage: 5 V DC
Low-profile design suitable for tight spaces
Mounting: standard 40 mm mounting pattern compatible with small fans
Connector type: typical two- or three-pin low-voltage connector (verify before installation)

How to use

Install the fan in the enclosure or on the device so that airflow is directed toward the components requiring cooling. Secure the fan using compatible mounting holes or brackets and connect it to a stable 5 V DC source, observing correct polarity. If the fan has a multi-pin connector, confirm pin assignment before powering. Route wiring to avoid contact with moving blades and other hot surfaces. For continuous operation, ensure the fan receives rated voltage and is not obstructed by dust or debris.

Usage recommendations

Position the fan to create a clear intake and exhaust path; combine with passive heatsinks or additional fans for balanced airflow. Periodically inspect and, if necessary, clean the fan to maintain performance. When used with sensitive electronics, verify that vibration and acoustic levels meet system requirements and consider rubber dampers or grommets to reduce mechanical noise transmission.
