Who it fits

Key specs explained for this fan

Fan Size: 25mm

The fan measures 25 by 25 by 10 millimeters. This tiny footprint allows it to fit into cramped areas where standard 120mm or 140mm fans will not. You will find this size useful for cooling 3D printer hotends, small routers, or compact DIY projects. It is not intended for main chassis airflow but for precise, localized cooling in tight spaces.

Max Fan Speed: 7000PRM

The motor spins at up to 7000 revolutions per minute. This high speed generates significant airflow for such a small unit. You benefit from rapid heat removal for sensitive components like extruders or VR glasses. However, higher speeds typically increase noise. Compare this to larger fans that move more air at lower, quieter speeds for general case ventilation.

Noise Level: 18.8dBA

The fan produces 18.8 decibels of sound at maximum speed. This is a low noise level, making it suitable for environments where quiet operation matters. You can use it in a bedroom setup or near a desk without distraction. Standard 120mm case fans often run quieter at lower speeds, but this micro fan offers a balance of performance and silence for its size.

Max Airflow: 1.35CFM

The fan moves 1.35 cubic feet of air per minute. This volume is modest compared to full-size PC case fans, which often exceed 100 CFM. You should view this spec as sufficient for small electronics cooling rather than whole-case air exchange. It helps dissipate heat from small components like Raspberry Pi boards or TV boxes where space is limited.

Static Pressure: 2.32mmH₂O

The fan generates 2.32 millimeters of water column in static pressure. This measure indicates how well the fan pushes air through resistance, such as dense heatsinks or filters. While low for a standard case fan, this pressure is adequate for open-frame cooling tasks. You will use this spec to ensure the fan can overcome minor airflow restrictions in tight enclosures.

Compact Build and RGB Features

According to the listing, this WINSINN fan measures 25 by 25 by 10 millimeters. Its small physical footprint allows it to fit into tight spaces where larger fans cannot. You will find this size useful for cooling 3D printer hotends, routers, or small PC cases. The unit weighs very little, which reduces stress on mounting points in delicate electronics.

The fan uses hydraulic bearings, which the listing states offer a lifespan of 35,000 hours. This bearing type balances performance with noise levels. At 7000 RPM, it moves 1.35 CFM of air while generating 18.8 dBA of sound. This quiet operation makes it suitable for environments where noise matters, such as near workstations or living room equipment.

Lighting is handled by RGB LEDs that cycle through colors. The listing notes this feature adds visual appeal without affecting cooling performance. The fan connects via a 2-pin XH2.54 connector with a 300mm cable. This standard connector type makes wiring easier for DIY projects. You can integrate it into custom setups without needing proprietary adapters. The 24-volt rating ensures compatibility with most 3D printer extruder boards and similar low-voltage systems. Overall, the build focuses on utility in small form factors.

Setup and everyday use

Installing these fans requires a direct connection to a 24-volt power source. The listing includes an XH2.54 to 2-pin connector with a 300-millimeter wire. You will need to match this connector to your power supply or controller. This setup is common in 3D printer extruder assemblies or small DIY electronics projects. The fan draws 0.05 amperes at 1.2 watts, so it places minimal load on your system. Daily operation relies on its hydraulic bearing design, which the manufacturer rates for 35,000 hours of life. This suggests stable performance over time without frequent maintenance. The RGB lighting activates when power is applied, providing visual feedback that the unit is running. With a noise rating of 18.8 dBA, the fan operates quietly even at its maximum speed of 7000 RPM. You can expect consistent airflow of 1.35 CFM and static pressure of 2.32 mmH2O. These figures indicate it is well-suited for moving air through small heatsinks or ventilation grilles. The compact size allows it to fit into tight spaces like router enclosures, TV boxes, or VR headsets. You do not need complex mounting hardware, as the small form factor integrates easily into existing designs. The 24-volt requirement means it is not compatible with standard 12-volt PC case fans without a voltage converter. Ensure your power source matches the rated voltage to avoid damage. The included four-pack offers redundancy, allowing you to replace units if one fails within the two-year warranty period. This makes it a practical choice for critical cooling applications where reliability matters.

Check compatibility before buying

Before you buy, verify your power supply matches the 24-volt requirement. This fan will not work with standard 12-volt PC systems. Check that your controller has the correct XH2.54 2-pin connector. You may need adapters if your existing wiring uses different plugs. Keep in mind that this unit is designed for small electronics, not large computer cases. It fits well in 3D printers, routers, or tiny DIY projects. The hydraulic bearing suggests a long lifespan, but you should still keep dust away from the intake. Clean it gently with compressed air every few months. This fan complements larger case fans by handling localized heat in tight spots. Use it alongside your main airflow setup for specific components. Ensure your mounting holes align with the 25mm spacing. Double-check the wire length is sufficient for your layout. This product is a niche tool for specific cooling needs.

Check before you buy

• Verify your power source provides 24 volts DC
• Confirm your controller has an XH2.54 2-pin connector
• Ensure mounting holes match the 25mm square size
• Check if the 300mm wire reaches your power source
