Question 1

What is the size of these cooling fans?

Accepted Answer

These cooling fans are 40mm x 40mm x 10mm in size. This compact design makes them suitable for small spaces such as 3D printers or other devices with limited room.

Question 2

Are these fans compatible with my computer's USB ports?

Accepted Answer

Yes, these fans use a standard USB connector and are powered via a USB port on your device. However, check the voltage requirement of your system to ensure it matches the 5V DC provided by this fan.

Question 3

How much airflow do these fans provide?

Accepted Answer

These fans offer an airflow of 12.4 CFM (cubic feet per minute), which is sufficient for cooling small devices like DVRs, NAS drives, and routers but may not be as powerful as larger fans for more demanding applications.

Question 4

Can I use these fans with a Raspberry Pi?

Accepted Answer

These mini fans should work well with a Raspberry Pi if you need additional cooling. The 5V DC power requirement is compatible with the Raspberry Pi's USB ports, and they are small enough to fit in tight spaces like inside a case.

Question 5

What type of bearing do these fans use?

Accepted Answer

These fans feature sleeve bearings, which provide reliable running but may not be as durable or long-lasting as ball bearings. They offer low-noise operation and low vibration during operation.

Question 6

How many fans are included in the package?

Accepted Answer

The package includes 2 pcs of 40mm mini cooling fans with USB cables. This allows you to install one fan per device if needed, or use them for multiple smaller devices.

Question 7

What is the wire length on these fans?

Accepted Answer

Each fan comes with a cable that is 500mm in length. This should be sufficient for most applications but may need an extension cord if your device requires a longer connection to the power source.

Question 8

Are these cooling fans suitable for noisy devices?

Accepted Answer

Yes, these fans are designed to be quiet and low-vibration. With a noise level of 16.63 dB-A, they should help reduce unwanted noise in your setup without compromising on airflow.

Question 9

Can I use these fans with my router or switch?

Accepted Answer

These mini cooling fans can be used to improve the cooling performance of routers or switches that may overheat due to high temperatures. They are ideal for replacing noisy or broken 5V 40mm fans in such devices.

Question 10

How do I install these fans into a device?

Accepted Answer

Installation is straightforward; simply plug the USB cable into an available USB port on your device, and connect it directly to a power source. Ensure that the fan fits securely within the designated space and does not interfere with other components.
