DC4020F High-Airflow 40mm Fan Advantages
DC4020F combines a 20mm frame depth, broad speed choices, and multi-voltage support for compact systems with higher airflow demand.
20mm Deep Frame for Stronger Cooling
The deeper 40×40×20mm body gives DC4020F more airflow capacity than shallower 40mm fans while keeping the same face size.
Wide Speed Range from 3500 to 11000RPM
Multiple speed levels allow engineers to choose between low-noise operation, mid-range airflow, and higher-output cooling within one fan series.
13.76CFM Airflow and 13.89mmH₂O Pressure
The high-speed versions support both air volume and pressure, making DC4020F useful for compact systems with moderate-to-high airflow resistance.
C/B Bearings and Multi-Voltage Options
C/B bearing choices and 5V/12V/24V models make DC4020F adaptable to many compact electronics and power architectures.
YCCFAN DC4020-F Product Overview
Understand the key design details of DC4020-F, including structure, material safety, performance range, and function options.
DC4020F is a deeper 40mm DC cooling fan designed for products that need more cooling capacity than 10mm or 15mm compact fans. The 20mm frame allows stronger airflow generation and better pressure support.
The fan uses glass fiber reinforced plastic and PBT UL94V-0 materials, with C/B bearing options and optional FG, RD, PWM, auto restart, and polarity protection for flexible system integration.

DC4020F Applications for Higher-Load Compact Cooling
Designed for compact systems that need stronger airflow and pressure support than thinner 40mm fans while still using a 40mm footprint.
Get Cooling Support
Higher-Load Compact Electronics
DC4020F is suitable when compact electronics need more airflow than thinner 40mm fans can provide.
Power Supply and Converter Cooling
The higher airflow and pressure support can help cool power supplies, DC converters, and driver modules with concentrated heat.
Compact Industrial Control Units
5V/12V/24V models and control functions make DC4020F suitable for compact control units with different power architectures.
Moderate-Resistance Air Paths
With up to 13.89mmH₂O pressure, DC4020F can support vents, compact ducts, and denser layouts that need pressure assistance.
Low-Noise to High-Output Configurations
The broad speed range allows selection for quiet baseline airflow or stronger cooling when thermal load increases.
