Who it fits
Good fit for
This fan set suits Raspberry Pi users who need reliable cooling without added noise. It is ideal for builders working with Pi 4, Pi 3, or Pi Zero boards. The dual-voltage interface helps those who want to choose between 3.3V and 5V power options. You will find it useful if you use standard Pi cases or the RetroFlag NESPI Case. The four-pack size is convenient for setups requiring multiple fans or spare parts. It fits well in small form-factor projects where space is limited.
Who should skip it
You should look elsewhere if you need fans for standard desktop PC cases. These 30mm units are too small for typical ATX or mid-tower chassis. They are also not suitable for larger SBCs that require 120mm or 140mm cooling. If you need PWM control or smart fan curves, this product lacks that feature. The manual switch between voltages may not fit automated systems. Users seeking silent operation below 10dBA will also find this option too loud.
Verdict: This is a practical, quiet cooling option for small single-board computers. It fits well in compact Raspberry Pi builds.
Key specs explained for this fan
Fan Size 30mm
This measurement describes the physical footprint of the fan blades. At 30 millimeters, the unit is significantly smaller than standard 120mm or 140mm PC case fans. You will need to verify that your computer chassis or specific device has mounting holes compatible with this compact size. It is ideal for tight spaces where larger fans cannot fit.
Noise Level 15.92dBA
This value indicates the acoustic output of the fan during operation. A rating of 15.92 decibels is very low, meaning the fan will run nearly silently. You will likely not hear it over other computer components or room noise. This level of quietness is beneficial for workspaces or bedrooms where loud airflow is disruptive.
Voltage 3.3V 5V DC
This specification defines the electrical power required to run the fan. It supports both 3.3-volt and 5-volt direct current inputs. You can connect it to various single-board computers or development boards that provide either voltage standard. This flexibility allows you to use the fan with different types of hardware without needing special adapters.
Color Black-4pcs
This detail describes the visual appearance and quantity of the package. The fans are black, which helps them blend into dark computer cases or internal components. You receive four units in this specific variation. Having multiple fans allows you to create a more comprehensive cooling solution for your system or replace units if one fails over time.
Design and build quality details
The listing describes these fans as brushless units with a black finish. They measure 30x30x7mm, which defines their physical footprint. You will find the width listed as 0.3 inches, the height as 1.18 inches, and the length as 1.18 inches. The total weight for the four-pack is 3.53 ounces. This low mass makes them easy to mount without adding significant load to your Raspberry Pi board.
According to the listing, the design features a unique terminal interface with two separate terminals. This allows for a one-to-two interface connector setup. You can use this for dual speed mode by selecting between 3.3V and 5V DC power. The brushless motor is rated for a long life of 30,000 hours. This specification suggests the unit should remain stable over time without frequent replacement.
The build is intended for standard Raspberry Pi cases. It fits models B, B+, A+, 2, 3, 4, and Pi Zero variants. The compact 7mm thickness ensures it does not interfere with case lids or nearby components. You can also install these in RetroFlag NESPI Cases. The black color provides a neutral look that matches most single-board computer enclosures. The design prioritizes direct mounting compatibility over complex cable management.
Setup and everyday use notes
Installation involves connecting the fan to your single-board computer. The listing specifies a unique terminal interface with two separate terminals. This design allows for a one-to-two interface connector. You can use this for dual speed mode. The product supports both 3.3V and 5V DC inputs. This flexibility lets you match the power supply to your specific board requirements. You will find compatibility with Raspberry Pi models B, B+, A+, 2, 3, and 4. It also works with Pi Zero and Zero W. Other robotic projects and development boards are listed as compatible targets. The fan fits most standard Raspberry Pi cases. It is also confirmed to work with the RetroFlag NESPI Case. You should verify your case dimensions against the fan size of 30x30x7mm. Daily use relies on the brushless motor design. The data states a noise level of 15.92dBA. This low decibel rating suggests quiet operation during routine tasks. The listing claims a long life of 30,000 hours. This figure implies sustained performance without frequent replacement. The black finish is part of the standard unit. You receive four fans in this specific variation. The total weight for the pack is 3.53 ounces. This light weight makes handling and mounting straightforward. Ensure your power source matches the voltage options provided. The separate terminals require careful wiring. You must connect each terminal correctly to achieve the desired speed mode. This setup process is simple if you follow the voltage specifications. The compact size ensures it does not obstruct other components. You can install it in tight spaces within your case.
Before you buy this fan
You need to verify that your Raspberry Pi model matches the listed compatibility. The product supports Pi 4, 3, 2, B+, B, A+, Zero, and Zero W. It also fits most standard cases and the RetroFlag NESPI Case. Check your specific case dimensions to ensure the 30x30x7mm footprint fits without obstruction. The dual speed mode requires you to connect the fan to either 3.3V or 5V DC power. You must manage the wiring yourself since the connector separates for this interface. Long life is rated at 30,000 hours, but you should keep the area around the fan clear of dust to maintain that 15.92dBA noise level. This fan is a niche component for single-board computers. It does not replace standard 120mm or 140mm case fans used in larger desktop towers. You should view it as a specialized add-on for your development board or retro gaming setup. Ensure you have the correct power supply ready for your chosen voltage setting.
Check before you buy
- Confirm your Raspberry Pi model is supported by the listing.
- Check that your case allows the 30x30x7mm fan size.
- Verify you can provide 3.3V or 5V DC power.
- Ensure the terminal interface matches your wiring setup.
