All these devices are designed for cooling electronics, enclosures, and computer components, but they differ significantly in power requirements, physical dimensions, and control features, which dictate their practical application.
⚙️ Below is a technical specifications comparison table outlining operational voltage, frame size, connector type, and construction features that determine hardware compatibility.
| Parameter | Delock DC Axial Fan 12 V 40 x 40 x 28 mm | Delock Axial Fan 24 V 40 x 40 x 28 mm 67651 | Delock Axial Fan 48 V DC, 60 x 60 x 25 mm, 2-Pin Connector, Black | Delock Axial Fan 48 V DC 120 mm with 2-Pin Connector Black | Delock 80mm Axial Fan 48V DC with 4-Pin PWM Connector | DELOCK Axial Fan 230 V AC with Filter | Practical conclusion |
|---|
| Brand | DELOCK | DELOCK | DELOCK | DELOCK | DELOCK | DELOCK | All compared products are from the same manufacturer and built for reliable cooling. |
| Application | Cooling computer components, electronics, and enclosures | Efficient cooling and airflow management for DIY and equipment | Cooling electronic components and computer systems | Industrial or electronic equipment cooling | Industrial applications, server enclosures, custom hardware | Ventilation and cooling in enclosures and technical setups | The main distinction lies in power requirements and the intended operating environment. |
| Operating voltage | 12 V DC | 24 V DC | 48 V DC | 48 V DC | 48 V DC | 230 V AC | The fan voltage must strictly match the power source available in your setup. |
| Dimensions | 40 x 40 x 28 mm | 40 x 40 x 28 mm | 60 x 60 x 25 mm | 120 x 120 x 25 mm | 80 x 80 x 25 mm | Standard size with filter | Physical dimensions determine the mounting space and airflow volume. |
| Connector and control | Standard connection | Standard connection | 2-pin connector | 2-pin connector | 4-pin PWM connector | AC power with filter | PWM allows precise speed control, while the AC version runs directly on mains power. |
◎ The following table evaluates product suitability for various use cases, power requirements, and operational environments.
| Use case | Recommended product | Why |
|---|
| Standard PC and electronics cooling on 12V power | Delock DC Axial Fan 12 V 40 x 40 x 28 mm | Ideal for standard low-voltage circuits and compact enclosures requiring a 12 V power supply. |
| Equipment requiring 24V power | Delock Axial Fan 24 V 40 x 40 x 28 mm 67651 | Offers the same compact 40x40 mm dimensions but is engineered for 24 V hardware environments. |
| Industrial 48V systems with basic connection | Delock Axial Fan 48 V DC, 60 x 60 x 25 mm, 2-Pin Connector, Black or Delock Axial Fan 48 V DC 120 mm with 2-Pin Connector Black | Suited for specialized high-voltage DC setups needing standard 60 mm or 120 mm frame sizes. |
| Precise speed management in 48V setups | Delock 80mm Axial Fan 48V DC with 4-Pin PWM Connector | Features PWM control for optimized thermal management and noise levels in server environments. |
| Mains power operation with dust protection | DELOCK Axial Fan 230 V AC with Filter | Operates on standard 230 V AC household power and includes an integrated filter to prevent dust buildup. |
The primary difference between the Delock DC Axial Fan 12 V 40 x 40 x 28 mm and the alternatives is its focus on standard 12 V low-voltage systems within a compact 40x40 mm form factor. This fan is best suited for builders, technicians, and hobbyists maintaining or assembling compact electronics and computer hardware with matching power requirements. You should prefer this model if your setup runs on 12 V and demands a small, reliable cooling fan.
