Manufacturer description

The GDSTIME Dual 40mm USB Fan set gives you two compact 40x40x10mm (4010) brushless cooling fans for small spaces where heat builds up: Raspberry Pi cases, routers, Roku boxes, small projectors, VR gear, aquariums, terrariums, and cosplay helmets.

GDSTIME's single board computers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Will these GDSTIME fans work with a Raspberry Pi?

Yes, the listing names Raspberry Pi as a use case. The fans plug into a 5V USB port instead of the GPIO header. Each 40x40x10mm fan has mounting holes 1.26 in. (32mm) apart, so check that your case accepts a 40mm fan.

Can I power these fans from a power bank?

Yes. They run on 5V USB power and work with laptops, power banks and standard USB outlets. Each fan draws 0.14A (0.7W), which is a light load for most power banks.

How loud are these 40mm USB fans?

The rated noise level is 25.8 dBA at the listed 5500 RPM. The 3-speed control lets you lower the speed if you need quieter operation.

How much airflow do they produce?

Each fan is rated for 6.12 CFM at 5500 RPM. That's enough for small enclosures like routers, streaming boxes, SBC cases and terrariums, but not for high-heat PC components.

Does it come with mounting hardware and how long is the cable?

Yes, mounting screws are included and each fan has a metal grill. The USB power cord is 35cm (1.15 ft) long. Check the product listing for current warranty terms.
